    OPINION AND ORDER
    STANCEU, Judge:
    Plaintiff USR Optonix, Inc. (“Optonix”) challenges the determinations of tariff
    classification that the United States Customs Service (“Customs”) applied to two products
    imported during a period beginning in November 1994 and concluding in May 1997.1 Optonix
    moves for summary judgment with respect to the classification of both products; defendant
    1
    The U.S. Customs Service now is renamed as the Bureau of Customs and Border
    Protection. See Homeland Security Act of 2002, Pub. L. 107-296, § 1502, 
    116 Stat. 2135
     (2002);
    Reorg. Plan for the Dep’t of Homeland Security, H.R. Doc. No. 108-32 (2003).
    Court No. 98-08-02723                                                                Page 2
    United States cross-moves for summary judgment in its favor, also with respect to both products.
    The court exercises jurisdiction pursuant to 
    28 U.S.C. § 1581
    (a) (2000).
    The first product at issue, designated as “P22-RE1,” is a white powder consisting by
    weight of at least 99 percent yttrium oxide (Y2O3). The remaining 1 percent or less of the
    product consists of europium oxide. The product is represented by the formula “Y2O3:Eu” and
    also is identified as “Yttrium Oxide: Europium Doped.” The second product, “P22-HCR2,” is a
    red powder comprised by weight of at least 90 percent yttrium oxygen sulfide (Y2O2S),
    10 percent or less europium oxygen sulfide (Eu2O2S), and 1 percent or less ferrous oxide (Fe2O3).
    Each product is used as a material in the production of phosphorescent coatings that are applied
    in the manufacturing of cathode ray tubes.
    The court awards summary judgment to defendant on the issue of the tariff classification
    of P22-RE1. The court concludes that there are no genuine issues of fact material to that tariff
    classification and that the tariff classification determined by Customs was correct, entitling
    defendant to judgment as a matter of law. The motions of both parties for summary judgment on
    the tariff classification of P22-HCR2 are denied because of the existence of one or more genuine
    issues of material fact.
    I. BACKGROUND
    Upon liquidation, Customs classified the entries of P22-RE1 that were made prior to
    1995 in subheading 2846.90.50, Harmonized Tariff Schedule of the United States (“HTSUS”),
    subject to duty at 3.7 percent ad valorem. The version of the provision that was in effect at the
    time of the pre-1995 entries of P22-RE1 read as follows:
    Court No. 98-08-02723                                                                                   Page 3
    2846   Compounds, inorganic or organic, of rare-earth metals, of yttrium or of
    scandium, or of mixtures of these metals:
    *          *          *
    2846.90        Other:
    *          *          *
    2846.90.50              Other. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.7%.
    Customs classified entries of P22-RE1 made in 1995 and thereafter in subheading
    2846.90.80, HTSUS, the provision that superceded the former subheading 2846.90.50, HTSUS.
    The article description for heading 2846 and the duty applicable to the subheading at issue,
    3.7 percent ad valorem, remained unchanged.
    Upon liquidation, Customs classified entries of P22-HCR2 in subheading 3206.50.00,
    HTSUS. At the time the entries were made, this tariff provision read, in relevant part, as
    follows:
    3206    . . . inorganic products of a kind used as luminophores, whether or not
    chemically defined:
    *         *          *
    3206.50.00     Inorganic products of a kind used as luminophores. . . . . . . .10.0%
    HTSUS, 1994.2
    Plaintiff protested the classification determinations that Customs made upon liquidation.
    Following denial of the protests, plaintiff commenced this action.
    2
    During the time plaintiff imported the subject entries, the duty rate was reduced in
    stages, as follows: 1995, 9.3%; 1996, 8.6%; 1997, 7.9%.
    Court No. 98-08-02723                                                                Page 4
    A. Contentions of the Parties on the Classification of P22-RE1
    Defendant maintains that Customs was correct in determining upon liquidation to classify
    P22-RE1 in subheading 2846.90.50, HTSUS, and subsequently in subheading 2846.90.80,
    HTSUS. In challenging that determination, plaintiff’s principal argument is that P22-RE1 is
    excluded from the scope of heading 2846 because it is a mixture of two compounds (i.e., yttrium
    oxide and europium oxide) and therefore is not itself a “compound” within the meaning of the
    article description for the heading (“Compounds, inorganic or organic, of rare-earth metals, of
    yttrium or of scandium, or of mixtures of these metals”). On the basis of this assertion, plaintiff
    advocates classification in subheading 3824.90.39, HTSUS, free of duty. That provision pertains
    to “mixtures of two or more inorganic compounds”; the superior heading (heading 3824,
    HTSUS) is a “basket” heading that includes, inter alia, “chemical products and preparations of
    the chemical or allied industries . . . not elsewhere specified or included.”
    Plaintiff claims an alternative classification in subheading 2846.90.20, HTSUS, the
    article description for which is “[m]ixtures of rare-earth oxides or of rare-earth chlorides.”
    Plaintiff argues that, should the court determine that P22-RE1 falls within the scope of heading
    2846, the court should rule that P22-RE1 is classified in subheading 2846.90.20 based on its
    assertion that both yttrium oxide and europium oxide are rare-earth oxides.
    Defendant argues that P22-RE1 is correctly classified in subheading 2846.90.80, HTSUS,
    (and in the predecessor subheading 2846.90.50, HTSUS, prior to 1995) because heading 2846, in
    defendant’s view, includes mixtures of oxides of yttrium and europium. As confirmation that the
    scope of the heading includes mixtures as well as compounds, defendant points to the article
    description for another eight-digit subheading within the heading, subheading 2846.90.20,
    Court No. 98-08-02723                                                                 Page 5
    HTSUS, which, as noted above, reads “[m]ixtures of rare-earth oxides or of rare-earth
    chlorides.” Defendant also directs the court’s attention to Explanatory Note 32.06, which
    contains a reference identifying headings 2843 to 2846 as appropriate for the classification of a
    mixture of yttrium oxide and europium oxide. Further, defendant points to the first paragraph of
    Explanatory Note 28.46 in support of its contention that heading 2846 includes mixtures of
    oxides of the metals mentioned in the article description for the heading; plaintiff relies on this
    same paragraph to support its argument that mixtures such as P22-RE1 are excluded from
    heading 2846 because they are not “compounds of mixtures” but instead are mixtures of
    compounds made intentionally for special purposes.
    Concerning plaintiff’s alternative classification of subheading 2846.90.20, HTSUS,
    which pertains to “mixtures of rare-earth oxides,” defendant contends that yttrium is not a rare-
    earth metal for tariff classification purposes and, consequently, that yttrium oxide is not a rare-
    earth oxide within the meaning of subheading 2846.90.20, HTSUS.
    B. Contentions of the Parties on the Classification of P22-HCR2
    Plaintiff argues that P22-HCR2 is not classifiable in subheading 3206.50.00, HTSUS,
    (“Inorganic products of a kind used as luminophores”) because it is not a finished product
    capable of use as a luminophore in the condition in which it is imported. Plaintiff asserts that the
    product requires further processing consisting of reduction of particle size and blending with
    other products to obtain the characteristics desired by the manufacturer of the cathode ray tube.
    Plaintiff submits that the correct classification is subheading 3824.90.39, HTSUS, which is free
    of duty. As noted previously, that subheading pertains to “mixtures of two or more inorganic
    compounds,” with the superior heading pertaining to “chemical products and preparations of the
    Court No. 98-08-02723                                                                  Page 6
    chemical or allied industries . . . not elsewhere specified or included.” At an early point in this
    litigation, plaintiff argued in the alternative that P22-HCR2 should be classified in subheading
    2846.90.20, HTSUS (“mixtures of rare-earth oxides. . .”).
    Defendant responds that P22-HCR2 falls within the definition of “inorganic products of a
    kind used as luminophores” despite the further processing alleged by plaintiff to be required. In
    rebuttal of plaintiff’s argument for alternative classification in subheading 2846.90.20, HTSUS
    (“mixtures of rare-earth oxides”), defendant maintains that the product is excluded from that
    provision because it is not comprised of a mixture of oxides of rare-earth metals.
    II. APPLICABLE LEGAL STANDARDS
    A. Standard of Review
    The court proceeds de novo in actions brought to contest the denial of a protest under
    section 515 of the Tariff Act of 1930. See 
    28 U.S.C. § 2640
    (a)(1). In a classification action,
    plaintiff has the burden of establishing that the government’s classification of the product was
    incorrect but does not bear a burden of establishing the correct tariff classification; instead, the
    correct tariff classification is to be determined by the court. See Jarvis Clark Co. v. United
    States, 
    733 F.2d 873
    , 878, reh’g denied, 
    739 F.2d 628
     (Fed. Cir. 1984).
    Customs classification decisions are entitled to a presumption of correctness by 
    28 U.S.C. § 2639
    (a)(1), but the presumption does not apply if the court is presented with a question
    of law by a proper motion for summary judgment. See Universal Elecs., Inc. v. United States,
    
    112 F.3d 488
    , 492 (Fed. Cir. 1997). The court affords deference to a classification decision by
    Customs to the extent that the decision has the power to persuade. See United States v. Mead
    Corp., 
    533 U.S. 218
    , 235 (2001); Skidmore v. Swift & Co., 
    323 U.S. 134
    , 140 (1944).
    Court No. 98-08-02723                                                                Page 7
    B. The General Rules of Interpretation and the Explanatory Notes
    The General Rules of Interpretation, HTSUS, govern the determination of tariff
    classification. See N. Am. Processing Co. v. United States, 
    236 F.3d 695
    , 698 (Fed. Cir. 2001).
    General Rule of Interpretation (“GRI”) 1, HTSUS, requires that tariff classification, in the first
    instance, “be determined according to the terms of the headings and any relative section or
    chapter notes.” GRI 1, HTSUS. GRIs 2 through 5 apply “provided such headings or notes do
    not otherwise require.” 
    Id.
    For guidance as to the scope and meaning of tariff terms, the court may resort to the
    Explanatory Notes, which, although not part of U.S. law, are “indicative of [the] proper
    interpretation” of the tariff schedule. Lynteq, Inc. v. United States, 
    976 F.2d 693
    , 699 (Fed. Cir.
    1992), quoting H.R. Conf. Rep. No. 100-576, 100th Cong., 2d Sess. 549 (1988), reprinted in
    1988 U.S.C.C.A.N. 1547, 1582.
    III. DISCUSSION
    A. Absence of a Genuine Issue of Material Fact Concerning the Tariff Classification
    of P22-RE1
    Under USCIT Rule 56, summary judgment is appropriate when the parties’ submissions
    “show that there is no genuine issue as to any material fact and that the moving party is entitled
    to a judgment as a matter of law.” USCIT Rule 56(c). The parties agree that P22-RE1 consists
    by weight of at least 99 percent yttrium oxide (Y2O3), a fact corroborated by the Material Safety
    Data Sheet (“MSDS”) prepared by the manufacturer, Kasei Optonix, Ltd. of Tokyo, Japan. As
    specified by the MSDS and as stated in an affidavit by plaintiff’s Technical Director, Mr.
    Susumu Omatoi, P22-RE1 is represented by the formula “Y2O3:Eu.” According to that affidavit,
    P22-RE1 is identified by the name “Yttrium Oxide: Europium Doped.”
    Court No. 98-08-02723                                                                 Page 8
    In its Rule 56 Statement of Material Facts Not in Dispute, plaintiff asserted that P22-RE1
    is a mixture of yttrium oxide and europium oxide, manufactured by separately producing the
    yttrium oxide and europium oxide components, intentionally blending them in specific
    quantities, and mixing them by heating in a kiln at high temperatures. See Pl.’s Statement of
    Material Facts Not in Dispute ¶ 8. In the pleadings, defendant denied this assertion but did not
    allege facts to the contrary. In its Statement in Response to Plaintiff’s Statement of Material
    Facts, defendant admitted “that P22-RE1 consists of a mixture of yttrium oxide with smaller
    amounts of europium oxide.” Def.’s Resp. to Pl.’s Statement of Material Facts ¶ 7. In the
    Statement of Material Facts Not in Dispute that it filed in support of its cross-motion for
    summary judgment, defendant stated that “P22-RE1 consists, by weight, of 99 percent or more
    yttrium oxide, and 1 percent or less europium oxide.” Def.’s Statement of Material Facts Not in
    Dispute ¶ 1.
    Although defendant initially agreed with plaintiff that P22-RE1 is a “mixture of
    compounds” and not a “compound of mixtures,” defendant in its post-argument brief advanced
    an alternative argument in favor of its classification position; in this alternative argument
    defendant departed in two respects from its earlier admissions concerning the composition of
    P22-RE1. In presenting this alternative argument, defendant regarded P22-RE1 as a
    “compound” instead of a “mixture.” Further, defendant asserted that the product consists of
    yttrium oxide and europium, rather than consisting of yttrium oxide and europium oxide.
    Despite defendant’s conflicting viewpoints, and the apparent disagreement with plaintiff,
    on the composition of P22-RE1, the court finds that there is no genuine issue of fact material to
    the tariff classification of P22-RE1, for two reasons. First, much of the apparent factual
    Court No. 98-08-02723                                                                 Page 9
    disagreement, to the extent it is relevant to the classification issue presented, is resolved by
    assigning the proper meaning to the term “compounds” as used in the article description for
    heading 2846. That meaning is a question of law, not of fact. See David W. Shenk & Co. v.
    United States, 
    21 CIT 284
    , 286, 
    960 F. Supp. 363
    , 365 (1997). As discussed in the next section,
    the court concludes that in using the term “compounds” in the heading, Congress did not intend
    this term and the term “mixtures,” which is used in a subheading of the heading, to be read as
    mutually exclusive. Instead, the term “compounds,” as used in the heading, is properly
    understood to be broader than such terms as “chemical compounds” or “separate chemically
    defined compounds” and to include some products that also are described by the term
    “mixtures.” 3 Second, the parties agree that P22-RE1 consists by weight of at least 99 percent
    yttrium oxide. The remainder, which is one percent or less by weight, either consists of
    europium oxide, as plaintiff contends and as defendant initially admitted, or, as defendant
    subsequently asserted based on its interpretation of the MSDS for P22-REI, consists of
    europium. This factual distinction is not material to the issue of classification of P22-RE1,
    because, in either case, the correct classification for P22-RE1 is subheading 2846.90.80, HTSUS
    (or, for entries prior to 1995, subheading 2846.90.50, HTSUS), for the reasons discussed later in
    this opinion.
    The court notes, in passing, that defendant has not asserted new facts to establish either
    that P22-RE1 is a “compound,” however defined, or that the product contains europium rather
    than europium oxide. Instead, these two contentions by defendant appear to be based on
    3
    The term “chemical compound” usually refers to “a substance composed chemically of
    two or more elements in definite proportions (as opposed to a mixture).” Oxford English
    Dictionary, 629, vol. III (2d ed. 1989).
    Court No. 98-08-02723                                                                Page 10
    inferences it draws from information already on the record, specifically, information presented in
    the MSDS for P22-RE1. Defendant draws these inferences from its submissions of affidavits by
    Mr. Larry D. Fluty, a Senior Science Officer in the Office of Laboratory and Scientific Services,
    Bureau of Customs and Border Protection, particularly a statement by Mr. Fluty that products
    similar to P22-RE1 (but not necessarily P22-RE1 itself) consist of “compounds” in which
    europium atoms are bound to oxygen atoms, replacing yttrium atoms in a yttrium oxide crystal
    lattice.
    Defendant presented two affidavits of Mr. Fluty that address P22-RE1. In the first
    affidavit, Mr. Fluty had stated that “[t]his combination of yttrium oxide and europium oxide is a
    mixture described by the Explanatory Notes to Heading 2846.” First Fluty Decl. ¶ 9 (Sep. 11,
    2002). In that same affidavit, Mr. Fluty, in referring to the term “compounds . . . of mixtures of
    these metals” as used in heading 2846, stated that “it is possible to have mixtures of compounds
    but not compounds of mixtures.” Id. ¶ 6. Citing to that statement by Mr. Fluty, defendant in its
    brief supporting its cross-motion for summary judgment argued that “[t]he language of heading
    2846, ‘compounds . . . of mixtures,’ moreover, is meaningless from a technical point of view. . . .
    To make sense out of the language, it must be understood, insofar as relevant here, as providing
    for mixtures that have as ingredients the compounds named in the heading, i.e., compounds of
    rare earth metals and compounds of yttrium.” Def.’s Br. in Opp’n to Pl.’s Mot. for Summ. J., &
    Cross-Mot. for Summ. J. at 7 n.2. In short, defendant argued at that time that “compounds of
    mixtures” is the equivalent, in the context of the heading, of “mixtures of compounds.”
    In his second affidavit on P22-RE1, Mr. Fluty described products similar to P22-RE1 as
    products in which a europium atom replaces a yttrium atom in a crystal lattice consisting of the
    Court No. 98-08-02723                                                                Page 11
    yttrium oxide. Mr. Fluty pointed out that the MSDS for P22-RE1 states as follows:
    “Classification if single or mixed: Single Product.” He further stated in his affidavit his opinion
    that the chemical formula stated in the MSDS, Y2O3:Eu, “means yttrium oxide containing an
    indeterminate amount of europium” and that this formula “indicates that the product should be
    considered a single chemical compound.” Second Fluty Decl. ¶ 13 (Mar. 17, 2004). In its post-
    argument brief, defendant maintained its position that heading 2846 encompasses mixtures
    within its scope but, on the basis of the second affidavit of Mr. Fluty, contended in the
    alternative “that if the Court determines that Heading 2846 covers only compounds, and not
    mixtures of compounds, then P22-RE1 was correctly classified there because it is a single
    compound consisting of yttrium oxide and europium.” Def.’s Br. in Reply to Pl.’s Post-
    Argument. Br. at 6.
    In stating that the remainder is “europium,” defendant has not disputed that the remaining
    europium may exist in the product in the form of europium oxide and has not offered to prove
    any facts relevant to this question. Defendant has not attempted to show how europium, which is
    regarded as having an extremely high affinity for oxygen, could exist in its metallic form, i.e., as
    a separate element, within a powdered mixture rather than being present in the mixture in the
    form of europium oxide. Rather, defendant’s reference to the remainder being “europium”
    appears to be related to its argument that “if the Court determines that Heading 2846 covers only
    compounds, and not mixtures of compounds, then P22-RE1 was correctly classified there
    because it is a single compound consisting of yttrium oxide and europium.” Defendant’s
    contention apparently refers in part to the aforementioned statement, set forth in paragraph 14 of
    Mr. Fluty’s second affidavit on P22-RE1, to the effect that products such as P22-RE1 typically
    Court No. 98-08-02723                                                                  Page 12
    have a “single phase” chemical structure consisting of yttrium oxide and europium bound
    together in a crystal lattice, in which europium atoms replace yttrium atoms in the crystal lattice.
    Mr. Fluty’s statement, however, appears to avoid making any direct statement that P22-RE1
    actually consists of such a crystal lattice.
    As discussed infra, the uncontested facts are sufficient to establish that P22-RE1 does not
    conform with established definitions of the terms “chemical compound” or “separate chemically
    defined compound” but also are sufficient to establish that P22-RE1 is a “compound” within the
    scope of the term “compounds” as used in heading 2846. It is immaterial to this conclusion
    whether the portion of the product not consisting of yttrium oxide consists of europium or
    europium oxide. Nor does the classification within heading 2846 depend on whether europium
    atoms are bound to oxygen atoms, replacing an indefinite number of yttrium atoms within a
    yttrium oxide crystal lattice. Because there is no genuine issue of fact that is material to the
    classification of P22-RE1, the court concludes that summary judgment is the appropriate
    disposition of the classification issue plaintiff has raised with respect to this product.
    B. P22-RE1 Is Classified under Heading 2846, HTSUS
    In the various pleadings, the parties have identified two headings as relevant to the
    classification issue presented by P22-RE1. They are heading 2846, HTSUS, (“Compounds,
    inorganic or organic, of rare-earth metals, of yttrium or of scandium, or of mixtures of these
    metals”) and heading 3824, HTSUS (“chemical products and preparations of the chemical and
    allied industries . . . not elsewhere specified or included”). The court has considered both of
    these headings and heading 3206, HTSUS, to which the parties also have referred in this case.
    The latter heading includes within its scope “inorganic products of a kind used as luminophores,
    Court No. 98-08-02723                                                              Page 13
    whether or not chemically defined.” Neither the court nor the parties have identified any other
    heading of the HTSUS that merits consideration.
    The court concludes that, by application of GRI 1, P22-RE1 is correctly classified under
    heading 2846, HTSUS. The court reaches this conclusion for the following reasons: (1)
    Heading 3824 is excluded from consideration if P22-RE1 is elsewhere specified or included or if
    it answers to descriptions in heading 2843 or 2846; (2) Heading 3206 is excluded from
    consideration by the terms of that heading, as construed according to guidance in the relevant
    Explanatory Note; and (3) P22-RE1 answers to a description in, and is included in, heading
    2846, because it is described by a term of that heading, “compounds . . . of mixtures of these
    metals,” with “these metals” referring to rare-earth metals, yttrium, and scandium. In the
    discussion below, the court discusses in further detail the reasoning underlying its conclusions
    concerning the tariff classification of P22-RE1.
    1. Heading 3824 Applies Only if P22-RE1 Is Not Elsewhere Specified or Included
    Because heading 3824, HTSUS, contains the qualifying term “not elsewhere specified or
    included,” GRI 1 precludes classification of P22-RE1 under heading 3824 if P22-RE1 is
    described by heading 2846 or heading 3206. The same conclusion emerges from the application
    of Note 1(b) to Section VI, HTSUS, which provides in relevant part that “goods answering to a
    description in heading 2843 or 2846 are to be classified in those headings and in no other
    heading of this section.” Headings 3824 and 3206, like heading 2846, are in Section VI of the
    HTSUS. Accordingly, the issue presented is whether P22-RE1 falls within the scope of either
    heading 2846 or heading 3206, HTSUS.
    Court No. 98-08-02723                                                                Page 14
    2. Heading 3206 Does Not Include Mixtures of Yttrium Oxide and Europium Oxide
    The court concludes that P22-RE1 is not properly classified under heading 3206. The
    Explanatory Notes offer relevant guidance on the intended scope of heading 3206 and its
    relationship to the intended scope of heading 2846. Explanatory Note 32.06 states that “[t]he
    heading [i.e., 3206] does not cover products answering to descriptions in headings 28.43 to
    28.46 (e.g., a mixture of yttrium oxide and europium oxide), however put up and whatever their
    intended use.” EN 32.06 (emphasis in original). The parenthetical example used to identify the
    group of products excluded from heading 3206 and falling within headings 2843 to 2846
    describes by composition a product identical or highly similar to P22-RE1. Thus, Explanatory
    Note 32.06 clarifies that a class of products to which P22-RE1 appears to belong, i.e., those
    products consisting of a mixture of yttrium oxide and europium oxide, should not be classified
    under heading 3206, regardless whether they are of a kind used as luminophores.
    3. P22-RE1 Answers to a Description in Heading 2846 and Is Included Therein
    Explanatory Note 32.06 also provides guidance on whether P22-RE1 may be classified
    under heading 2846. The “mixture of yttrium oxide and europium oxide” chosen as an example
    by Explanatory Note 32.06 is intended not only to direct the reader away from heading 3206, but
    also to refer the reader to classification under heading 2846. Implicit in the Note is that a
    mixture of yttrium oxide and europium oxide answers to a description in the group of headings
    consisting of headings 2843, 2844, 2845, and 2846. However, headings 2843 through 2845 refer
    to classes of goods that differ considerably from mixtures of yttrium oxide and europium oxide.
    Heading 2843 pertains generally to precious metals, heading 2844 addresses radioactive
    elements and compounds, and heading 2845 is confined to isotopes and compounds thereof.
    Court No. 98-08-02723                                                                  Page 15
    Explanatory Note 32.06, therefore, lends strong support to defendant’s position that P22-RE1 is
    properly classified under heading 2846. However, the terms of that heading, as interpreted
    according to their plain meaning and according to guidance contained elsewhere in the
    Explanatory Notes and specifically in Explanatory Note 28.46, raise an additional issue requiring
    the court to consider the matter further. That issue is whether, as plaintiff contends, P22-RE1 is
    excluded from heading 2846 because the heading contains terms that, in pertinent part, confine
    the scope to “[c]ompounds . . . of rare-earth metals, of yttrium . . . , or of mixtures of these
    metals.” Plaintiff argues, inter alia, that P22-RE1 is not a compound within the meaning of the
    heading.
    The threshold issue presented is the meaning of the term “compounds” as used in heading
    2846. The term “separate chemically defined compounds” is used elsewhere in the HTSUS,
    which in note 1(a) to chapter 28 expresses the general rule that chapter 28 is confined to
    “separate chemical elements” and “separate chemically defined compounds.” 4 Under note 1(a)
    to chapter 28, HTSUS, this general rule applies “[e]xcept where the context otherwise requires.”
    The General Explanatory Note to Chapter 28 defines the term “separate chemically defined
    compound” as follows: “A separate chemically defined compound is a substance which consists
    of one molecular species (e.g., covalent or ionic) whose composition is defined by a constant
    ratio of elements and can be represented by a definitive structural diagram. In a crystal lattice,
    the molecular species corresponds to the repeating unit cell.” The Note further explains that
    “[t]he elements of a separate chemically defined compound combine in a specific characteristic
    4
    Note 1(a) to ch. 28, HTSUS (“Except where the context otherwise requires, the
    headings of this chapter apply only to: . . . separate chemical elements and separate chemically
    defined compounds, whether or not containing impurities.”).
    Court No. 98-08-02723                                                                Page 16
    proportion determined by the valency and the bonding requirements of the individual atoms.
    The proportion of each element is constant and specific to each compound and it is therefore said
    to be stoichiometric.”
    P22-RE1 does not conform to the Explanatory Note definition of a “separate chemically
    defined compound.” As defendant acknowledges in citing Mr. Fluty’s second affidavit, the
    chemical formula for P22-RE1, Y2O3:Eu, “means yttrium oxide containing an indeterminate
    amount of europium.” As demonstrated by the chemical formula, the europium or europium
    oxide is not present within P22-RE1 in a specific or characteristic proportion that is determined
    by the valency and bonding requirements of the individual atoms of yttrium and oxygen that
    comprise the portion of the product that consists of yttrium oxide, which itself is a separate
    chemically defined compound. P22-RE1, therefore, is not stoichiometric. The proportion of
    europium or europium oxide is not chemically defined by molecular structure and instead is
    described as being present in the overall product only according to a range, i.e., at a level of one
    percent or less by weight. Even if, as defendant suggests, P22-RE1 is a single-phase product
    consisting of a yttrium oxide crystal lattice, with an indeterminate but small number of europium
    atoms replacing yttrium atoms within that lattice, the product still would fall outside the
    Explanatory Note definition of the term “separate chemically defined compound.” In the latter,
    “the molecular species corresponds to the repeating unit cell.” General Explanatory Note to
    Chapter 28. The HTSUS also uses the term “compounds, whether or not chemically defined.” 5
    Heading 2846 refers to “compounds” without specifying whether the term is intended to refer to
    5
    E.g., Note 6(c) to chapter 28, HTSUS, uses the term “compounds . . . whether or not
    chemically defined” (“Heading 2844 applies only to: . . . Compounds, inorganic or organic, of
    these elements or isotopes, whether or not chemically defined.”).
    Court No. 98-08-02723                                                              Page 17
    “separate chemically defined compounds” or, alternatively, to “compounds, whether or not
    chemically defined.”
    The court concludes that the term “compounds” as used in heading 2846 is intended to
    have a broader meaning than the more specific term “separate chemically defined compounds”
    and is intended to include certain products that also could be described as “mixtures,” which
    term commonly would include within its scope products consisting of two or more separate
    chemically defined compounds.6 One indication of this intent is the General Explanatory Note to
    Chapter 28, which instructs that heading 2846 is one of the specified exceptions to the general
    rule that Chapter 28 is confined to chemical elements and separate chemically defined
    compounds.7 Another indication of this intent is the inclusion within the heading of subheading
    2846.90.20, HTSUS, the article description for which is “[m]ixtures of rare-earth oxides or of
    rare-earth chlorides.” A third indication is the first paragraph of Explanatory Note 28.46, which
    indicates that the heading includes at least some products that can be described as “mixtures of
    oxides or hydroxides of these elements,” with “these elements” referring to yttrium, scandium,
    and the rare-earth metals. Therefore, the term “compounds” as used in heading 2846 cannot
    6
    The term “mixture” is defined as “[a]n aggregate composed of two or more distinct
    chemical components which retain their identities regardless of the degree to which they have
    become mingled.” McGraw-Hill Encyclopedia of Chemistry, 607 (5th ed. 1983).
    7
    The General Explanatory Note states that “[t]here are certain exceptions to the rule that
    this Chapter is limited to separate chemical elements and separate chemically defined
    compounds.” The Note then lists specific products falling within the exception, including:
    “Heading 28.46 - Compounds, inorganic or organic, of rare-earth metals, of yttrium or of
    scandium or of mixtures of these metals.”
    Court No. 98-08-02723                                                                Page 18
    properly be interpreted to mean “separate chemically defined compounds,” and it must be read to
    encompass some products that also may be described as “mixtures.” 8
    Plaintiff has pointed to this same provision of the Explanatory Notes, i.e., the first
    paragraph of Explanatory Note 28.46, in contending that the scope of heading 2846 is too narrow
    to encompass P22-RE1. Optonix relies on this paragraph and on the term “compounds” in the
    heading for its argument that “mixtures consisting of two or more compounds, made
    intentionally for special purposes, are expressly excluded from Heading 2846,” and that P22-
    RE1 is such a mixture. Pl.’s Post-Argument Br. at 3. The paragraph at issue reads as follows:
    This heading [i.e., heading 28.46] covers the inorganic or organic
    compounds of yttrium, of scandium or of the rare-earth metals of heading
    28.05 (lanthanum, cerium, praseodymium, neodymium, samarium,
    europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium,
    ytterbium, lutetium). The heading also covers compounds derived directly
    by chemical treatment from mixtures of the elements. This means that the
    heading will include mixtures of oxides or hydroxides of these elements or
    mixtures of salts having the same anion (e.g., rare-earth metal chlorides),
    but not mixtures of salts having different anions, whether or not the cation
    is the same. The heading will not therefore, for example, cover a mixture
    of europium and samarium nitrates with the oxalates nor a mixture of
    cerium chloride and cerium sulphate since these examples are not
    compounds derived directly from mixtures of elements, but are mixtures
    of compounds which could be conceived as having been made
    intentionally for special purposes and which, accordingly, fall in heading
    38.24.
    8
    A broader definition of the word “compounds” is consistent with a common meaning of
    the term found among dictionary definitions. The Merriam-Webster Collegiate Dictionary, 236
    (10th ed. 2002), defines “compound” as “something formed by a union of elements or parts.”
    The Oxford English Dictionary, 629, vol. III (2d ed. 1989), in the relevant part, defines
    “compound” as “[a] union, combination, or mixture of elements.” In turn, the Oxford English
    Dictionary includes a definition of “element” as “[a] component part of a complex whole,” a
    definition broader in scope than the chemical definition of the term “element.” Id. at 130, vol. V.
    Court No. 98-08-02723                                                                 Page 19
    EN 28.46 (emphasis in original). Under the interpretation of the paragraph advanced by
    plaintiff, the clause “the heading will include mixtures of oxides . . . of these elements” is
    qualified by the preceding sentence such that the only mixtures of yttrium oxide and europium
    oxide that fall within the scope of heading 2846 are those that are “derived directly by chemical
    treatment from mixtures of these elements.” Plaintiff construes the latter phrase, when read
    together with the later reference in the paragraph to “mixtures of compounds which could be
    conceived as having been made intentionally for special purposes,” to mean that a product
    obtained by intentionally mixing yttrium oxide and europium oxide for a special purpose is
    excluded from the scope of the heading and is not described by the term in the heading,
    “compounds . . . of mixtures of these metals.” Plaintiff’s interpretation of Explanatory
    Note 28.46 is that P22-RE1 is described by the term “mixtures of compounds” as used in the last
    sentence of the above-quoted paragraph from Explanatory Note 28.46 and thus is to be
    distinguished from what plaintiff views as the relevant term in heading 2846, which is
    “compounds . . . of mixtures of these metals.”
    The court does not agree with the meaning plaintiff ascribes to the first paragraph of
    Explanatory Note 28.46. Under plaintiff’s construction of the paragraph, mixtures of oxides of
    the metals of heading 2805 (which metals include yttrium and the rare-earth metals) would be
    excluded from heading 2846 if two such oxides were produced separately and blended
    intentionally for a special purpose. The reference in the second sentence, “compounds derived
    directly by chemical treatment from mixtures of these elements,” may be susceptible to more
    than one meaning when viewed standing alone, but its meaning, to the extent it is relevant to the
    issue presented by P22-RE1, is clarified by the following sentence. That third sentence, which is
    Court No. 98-08-02723                                                                Page 20
    introduced with the words “[t]his means that,” directly states that mixtures of oxides of the
    metals in question fall within heading 2846. Plaintiff’s interpretation would require the court to
    interpret the third sentence to mean that some, but not all, mixtures of oxides of the subject
    metals are within the heading, an interpretation that appears to be at odds with the plain meaning
    of that sentence. Moreover, it would be incongruous to ascribe to the word “compounds,” as
    used in the second sentence of the paragraph, a narrow meaning such as “separate chemically
    defined compounds” and at the same time ascribe to the term “compounds” as used in the
    heading the broader meaning that is required by the context and is clarified by other provisions
    of the Explanatory Notes.
    Plaintiff’s interpretation of the first paragraph of Explanatory Note 28.46 would seek to
    introduce ambiguity into the third sentence of the paragraph by resort to the last sentence in the
    paragraph, which contains a reference to “mixtures of compounds which could be conceived as
    having been made intentionally for special purposes.” The context of the last sentence, however,
    is the issue of which mixtures of salts fall within the heading and which do not; the last sentence,
    therefore, addresses an issue not relevant to the classification of P22-RE1, which is a mixture of
    oxides, not a mixture of salts. Even if considered relevant to the issue of classification of
    P22-RE1, the last sentence would present a problem when viewed against plaintiff’s premise that
    any mixture of compounds made intentionally for a special purpose is excluded from the
    heading. That problem is the contradiction that would arise in the instance of a mixture of salts,
    made intentionally for a special purpose, in which each salt has the same anion but a different
    cation. The contradiction does not arise when the paragraph is construed to establish a clear
    dividing line that would place such a mixture within the heading and exclude another mixture of
    Court No. 98-08-02723                                                                  Page 21
    salts, each of which had different anions, whether or not made intentionally for a special
    purpose.
    For these several reasons, plaintiff’s interpretation of the first paragraph of Explanatory
    Note 28.46 creates difficulties and internal conflicts that it is unable to resolve. Plaintiff’s
    interpretation of that paragraph also would appear to create a conflict with the express language
    of Explanatory Note 32.06, which directs the reader to heading 2846 to ascertain the
    classification of “a mixture of yttrium oxide and europium oxide” and does so without making an
    exception for the case of a mixture of yttrium oxide and europium oxide that is made by
    combining the two oxides intentionally for a special purpose.
    Plaintiff’s Technical Director, in his affidavit, described P22-RE1 as “Yttrium Oxide:
    Europium Doped.” 9 That the parties have not established whether the europium is bound in the
    structure of the crystal lattice of the yttrium oxide or is in the form of europium oxide mixed
    together with yttrium oxide is not a material fact because P22-RE1 would be classified under
    heading 2846 in either case. As discussed previously, the term “compounds” as used in heading
    9
    The use of the term “Yttrium Oxide: Europium Doped” in the affidavit of plaintiff’s
    Technical Director, Mr. Omatoi, to describe P22-RE1 suggests that the product could be shown
    to be identified in commerce as a “compound” (broadly defined) of yttrium (in this case, yttrium
    oxide), such that it would fall squarely within the terms of heading 2846. Under such an
    argument, regardless of whether the europium is present in the P22-RE1 as europium oxide that
    is mixed with yttrium oxide, or is present as europium atoms bound to oxygen atoms within the
    structure of a crystal lattice, that presence in a small quantity by weight would not prevent the
    product from conforming to a commercial definition of the term “yttrium oxide.” See Rohm &
    Haas Co. v. United States, 
    5 CIT 218
    , 225, 
    568 F. Supp. 751
    , 756 (1983) (“Congress is
    presumed to know the language of commerce, and to have framed tariff acts so as to classify
    commodities according to the general usage and denomination of the trade.”). Defendant did not
    develop this argument or support it with additional evidence of such a commercial designation;
    therefore, the court does not have before it evidence sufficient to establish that the product is
    considered to be a form of yttrium oxide for commercial purposes.
    Court No. 98-08-02723                                                                   Page 22
    2846 is not limited to “chemical compounds,” “stoichiometric compounds,” or “separate
    chemically defined compounds.” Various provisions of the Explanatory Notes, as well as the
    article description for subheading 2846.90.20 (“Mixtures of rare-earth oxides or of rare-earth
    chlorides”) clarify that the term “compounds” as used in heading 2846 includes some products
    that also fall within definitions of the term “mixtures.” If the europium is bound in the crystal
    lattice of the yttrium oxide compound, albeit in a non-stoichiometric proportion, P22-RE1 would
    be considered a “compound” of yttrium under some definitions of “non-stoichiometric
    compounds.” 10
    If P22-RE1 is actually a mixture of two separate chemically-defined compounds, yttrium
    oxide and europium oxide (as the parties initially appeared to agree), it nevertheless would fall
    within the scope of heading 2846, because the proper interpretation of the term “compounds” as
    used in the heading is sufficiently broad to include this product. Explanatory Note 28.46 states
    that P22-RE1 is covered by heading 2846 because this “heading also covers compounds derived
    directly by chemical treatment from mixtures of these elements. This means that the heading
    will include mixtures of oxides or hydroxides of these elements . . . .” Yttrium oxide and
    europium oxide in mixture form plainly would be described as “mixtures of oxides . . . of these
    10
    P22-RE1, if consisting of a single “crystal lattice” structure as described by defendant,
    possibly could conform to definitions of “non-stoichiometric compounds” as found in scientific
    references. For example, McGraw-Hill Encyclopedia of Chemistry defines “nonstoichiometric
    compounds” as “[c]hemical compounds in which the relative number of atoms is not expressible
    as the ratio of small whole numbers . . . . Nonstoichiometry is a property of the solid state and
    arises because a fraction of the atoms of a given kind may be (1) missing from the regular
    structure . . . (2) present in excess over the requirements of the structure . . . or (3) substituted by
    atoms of another kind . . . .” McGraw-Hill Encyclopedia of Chemistry at 665. The McGraw-Hill
    Encyclopedia of Chemistry further states that nonstoichiometry “is also well represented in the
    so-called insertion or intercalation compounds, in which a metallic element or neutral molecule
    has been inserted in a stoichiometric host.”
    Court No. 98-08-02723                                                                  Page 23
    elements.” As noted above, Explanatory Note 32.06 also indicates that a mixture of yttrium
    oxide and europium oxide should be classified under heading 2846.
    For these reasons, the court concludes that the terms of heading 2846, considered in the
    proper context of related provisions of the HTSUS and as informed by the guidance in the
    Explanatory Notes, encompass P22-RE1. Those terms describe P22-RE1 whether europium
    exists in the product as atoms of europium metal bound into a crystal lattice formed by yttrium
    oxide or whether the product contains, within a mixture, the separate chemically defined
    compound europium oxide.
    C. P22-RE1 Is Classified in Subheading 2846.90.80, HTSUS
    The court concludes that Customs was correct in classifying P22-RE1 in subheading
    2846.90.80, HTSUS (and, prior to 1995, in the predecessor provision, subheading 2846.90.50,
    HTSUS). Plaintiff’s alternative classification of subheading 2846.90.20, HTSUS, which pertains
    to “mixtures of rare earth oxides . . . ,” is incorrect because yttrium oxide is not a “rare-earth
    oxide” within the meaning of that term as used in subheading 2846.90.20, HTSUS.
    As plaintiff has pointed out, some technical references list yttrium among the rare-earth
    elements or otherwise indicate that yttrium oxide is a rare-earth oxide. Plaintiff has identified
    two such authorities, the CRC Handbook of Chemistry and Physics and The Phosphor
    Handbook.11 However, the court disagrees with plaintiff’s contention that the term “rare-earth
    oxides” as used in subheading 2846.90.20, HTSUS, includes yttrium oxide.
    11
    CRC Handbook of Chemistry and Physics, §§ 4-114, 4-115 (77th ed. 1996-97); The
    Phosphor Handbook at 178, 179 (Shingeo Shinionoya & William M. Yen eds., 1999).
    Court No. 98-08-02723                                                               Page 24
    Various dictionaries and technical references are in general agreement that the oxides of
    the elements with the atomic numbers 58 (cerium) through 71 (lutetium) comprise the “rare
    earths” and that the elements themselves are known as the “rare-earth elements” or “rare-earth
    metals.” Many, but not all, of the dictionaries and technical references consulted by the court
    consider atomic number 57 (lanthanum) to be a rare-earth element. The court has found that
    there is no general agreement as to whether atomic number 39 (yttrium) and atomic number 21
    (scandium) are rare-earth metals. Accordingly, there is no general agreement on whether the
    oxide of yttrium is one of the so-called “rare earths” or “rare-earth oxides.”
    For these reasons, each of the terms “rare-earth metals,” “rare earths,” and “rare-earth
    oxides,” when considered outside of any context, are ambiguous. The salient point, however, is
    that the article description for heading 2846, HTSUS, refers to yttrium and scandium in a context
    indicating that, for purposes of the heading, these two metals are not considered to be among the
    rare-earth elements. The heading identifies “[c]ompounds, inorganic and organic, of rare-earth
    metals, of yttrium or of scandium, or of mixtures of these metals.” The plain meaning of the
    words indicates an intent to regard yttrium and scandium as separate from the rare-earth metals.
    The same intent is apparent from the wording of the article description for the heading in which
    the rare-earth metals are classified. Heading 2805 provides for “[a]lkali or alkaline-earth metals;
    rare-earth metals, scandium and yttrium, whether or not intermixed or interalloyed; mercury.”
    Here also, the language indicates an intent to treat yttrium and scandium as separate from the
    rare-earth metals.
    Plaintiff states in its memorandum in support of its summary judgment motion that “[t]he
    Explanatory Notes to the HTSUS indicate that the definition of ‘rare earth’ metals includes not
    Court No. 98-08-02723                                                                 Page 25
    only those falling within the ‘Lanthanide Series’ of the periodic table of the elements (atomic
    numbers 58 through 71) but also the rare earth elements Lanthanum (atomic number 57),
    Yttrium (atomic number 39) and Scandium (atomic number 21).” Mem. of P. & A. in Supp. of
    Pl.’s R. 56 Mot. for Summ. J. at 21. Plaintiff has misinterpreted the Explanatory Notes. The
    Explanatory Notes, consistent with the terms of headings 2805 and 2846, instruct that scandium
    and yttrium are not to be considered rare-earth metals for purposes of the Harmonized System
    nomenclature. “Rare-earth metals (the term ‘rare-earth’ applies to their oxides) or lanthanons
    comprise the elements with atomic numbers from 57 to 71 in the periodic system . . . .” EN
    28.05(C). “This heading [i.e., heading 28.05] also covers scandium and yttrium which
    resemble the rare-earth metals quite closely . . . .” Id. (emphasis in original).
    Because yttrium oxide is not a rare-earth oxide for purposes of heading 2846, P22-RE1 is
    not described by the term “mixtures of rare-earth oxides” as used in the article description for
    subheading 2846.90.20, HTSUS. The high (99 percent or higher) yttrium oxide content excludes
    P22-RE1 from subheading 2846.90.40, HTSUS (“Other: Yttrium bearing materials and
    compounds containing by weight more than 19 percent but less than 85 percent yttrium oxide
    equivalent”), which was in effect beginning in 1995. Therefore, the correct classification for
    P22-RE1 is subheading 2846.90.80, HTSUS (prior to 1995, subheading 2846.90.50, HTSUS),
    subject to duty at 3.7 percent ad valorem. Because this is the classification determined by
    Customs upon liquidation, plaintiff’s classification claim, and its alternate classification claim,
    for P22-RE1 must be dismissed. Plaintiff has not met its burden of establishing that the
    government’s classification of this product is incorrect, and defendant is entitled to summary
    judgment on the issue of the tariff classification of P22-RE1.
    Court No. 98-08-02723                                                                  Page 26
    D. Issues of Fact Material to the Tariff Classification of P22-HCR2
    The parties agree that P22-HCR2 consists by weight of approximately 90 percent Y2O2S,
    which is known as yttrium oxygen sulfide or “yttrium oxysulfide,” approximately 10 percent
    Eu2O2S, which is europium oxygen sulfide or “europium oxysulfide,” and less than 1 percent
    Fe2O3, iron (“ferrous”) oxide. Also, it is undisputed that P22-HCR2 is used as a material in the
    production of phosphorescent coatings that are applied in the manufacturing of cathode ray
    tubes. The court concludes from the submissions of the parties, however, that at least one issue
    of fact material to the classification of this product otherwise exists that requires the court to
    deny the motions of both parties for summary judgment.
    In seeking summary judgment, plaintiff’s principal claim for classification of P22-HCR2
    is subheading 3824.90.39, HTSUS, which pertains to “mixtures of two or more inorganic
    compounds.” Plaintiff presented an alternative claim for classification of P22-HCR2 in
    subheading 2846.90.20, HTSUS, which provides for “[m]ixtures of rare-earth oxides or of rare-
    earth chlorides.” This alternative claim was not included in the complaint, nor has plaintiff
    sought to amend its complaint to include this claim.12 In its brief in support of summary
    judgment, plaintiff also asserted that “P22-HCR2 is also susceptible to classification under
    HTSUS subheading 2846.90.40, HTSUS.” That subheading applies to “[y]ttrium-bearing
    materials and compounds containing by weight more than 19 percent but less than 85 percent of
    yttrium-oxide equivalent.” Here also, plaintiff did not seek to amend its complaint to include
    12
    Were plaintiff to do so, the court would find this alternative claim to be meritless.
    P22-HCR2 differs from the goods of subheading 2846.90.20, HTSUS, in several respects. It
    contains a compound, yttrium oxysulfide, that is not a rare-earth oxide for tariff classification
    purposes. It also contains a small amount of iron oxide, which is not a rare-earth oxide.
    Court No. 98-08-02723                                                                 Page 27
    this claim.13 In its post-argument brief, plaintiff addressed only its principal claim for
    classification of P22-HCR2 in subheading 3824.90.39, HTSUS.
    With respect to plaintiff’s principal classification claim, subheading 3824.90.39, HTSUS,
    (“Mixtures of two or more inorganic compounds: Other”) describes P22-HCR2 by composition;
    however, the pertinent term of the superior heading is “chemical products and preparations of the
    chemical or allied industries (including those consisting of mixtures of natural products) not
    elsewhere specified or included.” Heading 3824, HTSUS (emphasis added). By application of
    GRI 1, heading 3824 is excluded from consideration if P22-HCR2 is specified or included by the
    terms of another heading.
    In its cross-motion for summary judgment, defendant claims that Customs was correct in
    classifying P22-HCR2 in subheading 3206.50.00, HTSUS, the article description for which is
    “[i]norganic products of a kind used as luminophores.” The pertinent language of the article
    description for the superior heading, heading 3206, HTSUS, is also “[i]norganic products of a
    kind used as luminophores.”
    The phrase “of a kind used as luminophores,” as used in heading 3206 and subheading
    3206.50, HTSUS, identifies a tariff provision controlled by principal use. See Primal Lite, Inc.
    v. United States, 
    182 F.3d 1362
    , 1363-64 (Fed. Cir. 1999) (holding that a heading with the
    phrase “of a kind used” is a principal use provision). “The purpose of ‘principal use’ provisions
    in the HTSUS is to classify particular merchandise according to the ordinary use of such
    13
    Plaintiff has not developed its argument for this second alternative claim. The court
    notes, however, that the presence of iron oxide, which is not a compound of yttrium, scandium or
    the rare-earth metals, would appear to exclude the product from heading 2846, even if plaintiff
    could show that the article description for subheading 2846.90.40, HTSUS, describes
    P22-HCR2.
    Court No. 98-08-02723                                                                   Page 28

    Schedules of the United States Annotated Into the Nomenclature Structure of the Harmonized
    System: Submitting Report at 34-35 (USITC Pub. No. 1400) (June 1983)).
    Additional U.S. Rules of Interpretation 1(a), HTSUS, provides that “[i]n the absence of
    special language or context which otherwise requires–a tariff classification controlled by use
    (other than actual use)14 is to be determined in accordance with the use in the United States at, or
    immediately prior to, the date of importation, of goods of that class or kind to which the
    imported goods belong, and the controlling use is the principal use.”
    The Court of Appeals for the Federal Circuit has held that delimiting the class or kind of
    goods to which the imported goods belong “[c]all[s] for a determination as to the group of goods
    that are commercially fungible with the imported goods.” Primal Lite, 
    182 F.3d at 1365

    particular species of which the [subject] merchandise is a member.” 
    Id. at 1364
    . The court may
    examine factors such as: (1) the general physical characteristics of the merchandise; (2) the

    The court concludes that heading 3206 and specifically, subheading 3206.50, HTSUS,
    do not establish an “actual use” provision so as to invoke the operation of Additional U.S. Rule
    of Interpretation 1(b). The language of the provision does not require establishing “the actual
    use made of the imports in the United States” as would a provision controlled by actual use. See
    Clarendon Mktg., 
    144 F.3d at 1468

    practicality of using the import in that manner; and (7) the recognition in the trade of this use.

    , 196 (1996). “Susceptibility,
    capability, adequacy, or adaptability of the import to the common use of the class is not
    controlling.” Carborundum, 63 C.C.P.A. at 102, 536 F.2d at 377 (citations omitted).
    In moving for summary judgment on the classification of P22-HCR2, Optonix challenges
    the Customs classification of P22-HCR2 under heading 3206 as a “product of a kind used as a
    luminophore,” contending that “[p]roducts that are commercially fungible with P22-HCR2 are
    not used as luminophores because of the need to further process these items in order to make
    them commercially usable.” Pl.’s Reply in Opp’n to Def.’s Cross-Mot. for Summ. J. at 15. In an
    affidavit by Mr. Richard Castello, a sales engineer for Optonix, plaintiff identified additional
    processing that P22-HCR2 is said to undergo before it is supplied to Optonix’s customer for use
    in manufacturing television picture tubes.
    To support its cross-motion for summary judgment, defendant relies, in part, on
    plaintiff’s statement in the protest that P22-HCR2 is used in the manufacture of phosphors for
    television screens. Defendant also relies on the second affidavit of Mr. Fluty on P22-RE1, which
    states that “‘P22’ is the name from the Electronics Industries Association (EIA) for a family of
    phosphors used in color cathode ray tubes and elsewhere.” Second Fluty Decl. ¶ 14. Some
    Court No. 98-08-02723                                                                  Page 30
    dictionary definitions identify “phosphors” as a subset, along with “fluorophores,” of
    “luminophores.” See Oxford English Dictionary, 1105, vol. V (2d ed. 1989) (“Other terms
    sometimes used synonymously with phosphor are luminophor . . . or fluorophor.”).15 Also
    relevant to the “principal use” issues are statements in another affidavit of Mr. Fluty, submitted
    by defendant, that identify the chemical mixture comprising P22-HCR2 as a “red luminescent
    phosphor” and a “pigment coated phosphor.” These statements were supported by reference to a
    process patent for producing pigment-coated phosphors, the documentation for which, attached
    to the affidavit, lists as an assignee Kasai Optonix, Ltd., the manufacturer of P22-HCR2.
    The court’s examination of the pleadings, admissions, and affidavits reveals at least one
    issue of fact material to the tariff classification of P22-HCR2. The principal issue of fact to be
    resolved is whether the class or kind of goods to which P22-HCR2 belongs were, at or
    immediately prior to the time of importation, principally used in the United States as
    “luminophores.” The relevant Explanatory Note contains the following definition: “Inorganic
    products of a kind used as luminophores are products which, under the action of visible or
    invisible radiations (solar rays, ultra-violet rays, cathode rays, X-rays, etc.), produce a
    luminescent effect (flourescent or phosphorescent).” EN 32.06(B). Based on this guidance, on
    Additional U.S. Rule of Interpretation 1(a), and on dictionary definitions of “luminophore” and
    “phosphor,” the court concludes that determination of the correct classification of P22-HCR2
    requires a factual determination whether the class or kind of goods to which P22-HCR2 belongs
    15
    A luminophor is defined therein as “[a] luminescent substance. . . . The generic term
    luminophor is subclassified into fluorophors . . . and phosphors. . . .” Id. at 99, vol. IX. A
    phosphor is “[a]nything that phosphoresces, or emits light without sensible heat” or in modern
    use “any substance exhibiting phosphorescence or fluorescence, esp. one that is an artificially
    prepared solid.” Id. at 708, vol. XI.
    Court No. 98-08-02723                                                                Page 31
    were, at or immediately preceding importation, principally used in the United States for their
    luminescent property. The court’s consideration of this issue is confined to the pleadings,
    admissions and supporting affidavits of the parties, which are not sufficient to resolve the issue.
    In summary, plaintiff alleges the existence of a class or kind of products not used as
    luminophores because of the need to further process these items in order to make them
    commercially usable. Defendant does not directly address the issues raised by the application of
    Additional U.S. Rule of Interpretation 1(a), HTSUS, but contends that “[t]he fact that the
    P22-HCR2 undergoes further processing after importation in the form of blending to meet a
    customer’s specification does not prevent it from being a kind of product (i.e., a phosphor) used
    as a luminophore, as the plaintiff argues.” Def.’s Br. in Reply to Pl.’s Post-Argument Br. at 9-10.
    In addition, the parties appear to be in disagreement on a physical characteristic of
    P22-HCR2. Defendant’s argument is premised in part on its contention that the product, as
    imported, is of a kind used as a luminophore, based on its characteristics and its use in the
    manufacturing of color cathode ray tubes. Plaintiff indicated that P22-HCR2, in the condition in
    which it is imported, i.e., before the processing plaintiff identifies as necessary to commercial
    use, does not luminesce or does so only crudely.
    Because the court has identified facts that are material to the proper application of
    Additional U.S. Rule of Interpretation 1(a), HTSUS, to the determination of the tariff
    classification of P22-HCR2, and because these facts remain in controversy, the motion and
    cross-motion for summary judgment of plaintiff and defendant, respectively, must be denied with
    respect to the classification of P22-HCR2.
    Court No. 98-08-02723                                                                  Page 32
    IV. CONCLUSION
    The court awards to defendant partial summary judgment based on its determination that
    there is no genuine issue of fact material to the classification of P22-RE1 and its conclusion that
    Customs was correct in classifying in subheading 2846.90.50, HTSUS, the entries of P22-RE1
    made prior to 1995 and in classifying in subheading 2846.90.80, HTSUS, the entries of P22-RE1
    made in 1995 and thereafter. The court concludes that summary judgment is not appropriate to
    resolve the dispute between the parties concerning the classification of P22-HCR2 because of the
    existence of at least one issue of fact material to the classification of this product. That issue, as
    discussed above, is whether the class or kind of goods to which P22-HCR2 belongs were, at or
    immediately preceding the time of importation, principally used in the United States for their
    luminescent property.
