    Before: SRINIVASAN and MILLETT, Circuit Judges, and
    SENTELLE, Senior Circuit Judge.
    Opinion for the Court filed by Circuit Judge SRINIVASAN.
    SRINIVASAN, Circuit Judge: In June 2012, the United
    States Coast Guard intercepted a Colombian vessel called the
    Mistby, which was transporting cocaine and marijuana to
    Panama. The three defendants in these consolidated cases
    pleaded guilty to conspiring to distribute, and possess with
    intent to distribute, the drugs on board the Mistby, in violation
    of the Maritime Drug Law Enforcement Act (MDLEA), 
    46 U.S.C. § 70501
     et seq., and the Controlled Substances Import
    and Export Act, 
    21 U.S.C. § 951
     et seq. Each defendant was
    sentenced to 10 years of imprisonment.
    The defendants now appeal on two grounds. First, they
    argue that the district court lacked subject-matter jurisdiction
    over their prosecutions because they were not on board the
    Mistby when it was intercepted. In the defendants’ view,
    Colombia’s assent to U.S. jurisdiction over individuals
    associated with the Mistby was limited to persons found on
    board the vessel. Second, the defendants contend that their
    offense of conviction is covered by the so-called safety-valve
    provision, 
    18 U.S.C. § 3553
    (f). That provision, in certain
    circumstances,      exempts       covered    offenses      from
    mandatory-minimum sentences such as the 10-year sentences
    imposed against the defendants.
    3
    We conclude that the district court had subject-matter
    jurisdiction over the defendants’ prosecutions, but that the
    defendants’ offense is covered by the safety-valve provision.
    We therefore vacate the defendants’ sentences and remand for
    resentencing.
    I.
    The Coast Guard first spotted the Mistby on the high seas
    about 70 nautical miles off the coast of Panama. When the
    Coast Guard approached, the Mistby fled, and its crew began
    to dump cargo overboard. The cargo turned out to be 22 bales
    of drugs, containing more than 220 kilograms of cocaine and
    more than 120 kilograms of marijuana.
    The Coast Guard eventually overtook the Mistby and
    boarded it to determine its nationality, at which point the
    Mistby’s captain claimed the vessel was registered in
    Colombia. The United States and Colombia have agreed by
    treaty to “cooperate in combating illicit traffic by sea.”
    Agreement to Suppress Illicit Traffic by Sea, Colom.-U.S., art.
    2, Feb. 20, 1997, T.I.A.S. No. 12,835. Pursuant to that treaty,
    the Coast Guard asked the Colombian Navy (i) to verify that
    the Mistby was registered in Colombia, and (ii) to grant the
    Coast Guard permission to search the vessel. See 
    id.
     art. 7. The
    Colombian Navy granted both requests. The Coast Guard then
    searched the Mistby and arrested the people on board, but the
    defendants were not among them.
    The next day, the Coast Guard asked the Colombian Navy
    to confirm that, under Article 16 of the treaty, the United States
    had jurisdiction over the Mistby. The Colombian Navy did so
    on June 26, stating that, under the “agreement signed by the
    governments of the United States and Colombia, [the United
    States could] exercise their jurisdiction.” Ardila M. Hector,

    Interpretation of Article 16(1) of the Maritime Agreement Col.-
    U.S. (June 26, 2012) (formatting modified).
    The Coast Guard memorialized the Colombian Navy’s
    response in a certification, which reads, in relevant part:
    On June 26, 2012, Colombian authorities
    confirmed and concurred with the United
    States’ interpretation of Article 16 of the
    Agreement, thereby waiving objection to the
    enforcement of United States law by the United
    States over the go-fast vessel MISTBY, all
    associated contraband, and persons on board.
    Salvatore J. Fazio, U.S. Coast Guard, Certification for the
    Maritime Drug Law Enforcement Act Case Involving Go-Fast
    Vessel Mistby (Colombia) ¶ 4.e (Aug. 10, 2012) (hereinafter
    Coast Guard Certification). “Accordingly,” the certification
    concludes, “the Government of the United States determined
    the go-fast vessel MISTBY was subject to the jurisdiction of
    the United States pursuant to 
    46 U.S.C. § 70502
    (c)(1)(C).” 
    Id. ¶ 4
    .f.
    Months    later,    the     three     defendants—Alfredo
    Mosquera-Murillo, Antonio Moreno-Membache, and Joaquin
    Chang-Rendon—were charged with conspiring to distribute,
    and possess with intent to distribute, the drugs transported on
    board the Mistby, in violation of 
    46 U.S.C. §§ 70503
     and
    70506(b), and 
    21 U.S.C. § 960
    (b)(1)(B) and (b)(2)(G). The
    government’s theory as to each defendant’s involvement was
    as follows: that Chang-Rendon (a civilian employee of the
    Colombian Navy) knew the patrol routes of Colombian and
    American law-enforcement vessels and passed that
    information along to Mosquera-Murillo; that Mosquera-
    5
    Murillo in turn conveyed the information to the people
    transporting the drugs; and that Moreno-Membache helped
    move the drugs to the Colombian coast and then load them onto
    the Mistby. At the time the defendants were charged, all three
    of them were still in Colombia. The United States thus
    requested extradition, which Colombia granted.
    Chang-Rendon and Mosquera-Murillo moved to dismiss
    the indictment on the ground that the district court lacked
    subject-matter jurisdiction over their prosecutions. The
    government claimed that the district court had jurisdiction
    under 
    46 U.S.C. § 70502
    (c)(1)(C), which applies if the vessel
    on which an MDLEA offense was committed is “a vessel
    registered in a foreign nation [and] that nation has consented or
    waived objection to the enforcement of United States law by
    the United States.” The defendants responded that, as shown
    by the Coast Guard’s certification, Colombia waived objection
    to the United States exercising jurisdiction over the “MISTBY,
    all associated contraband, and persons on board”—but not
    persons like the defendants who never set foot on the vessel.
    Coast Guard Certification ¶ 4.e.
    The district court rejected that argument. The court held
    that “a foreign government’s waiver of jurisdiction over a
    particular vessel . . . establish[es a district] court’s
    subject-matter jurisdiction over a subsequent prosecution of
    any land-based co-conspirators.” United States v. Mosquera-
    Murillo, 
    153 F. Supp. 3d 130
    , 158 (D.D.C. 2015). And in any
    event, the court explained, the notion that Colombia had not
    consented to the defendants’ prosecutions was difficult to
    square “with the Colombian government’s subsequent
    extradition of the defendants to the United States.” 
    Id. at 159
    .
    The defendants then pleaded guilty. In their plea
    agreements, they acknowledged that, given the quantity of
    6
    cocaine involved, the district court ordinarily would be
    required to impose a mandatory-minimum sentence of 10 years
    of imprisonment. See 
    21 U.S.C. § 960
    (b)(1)(B). But the
    defendants reserved their rights (i) to argue they were eligible
    for relief from that mandatory-minimum sentence under the
    safety-valve provision, 
    18 U.S.C. § 3553
    (f), and (ii) to appeal
    any contrary determination by the district court.
    The safety-valve provision states that sentencing relief is
    available only “in the case of an offense under” 
    21 U.S.C. §§ 841
    , 844, 846, 960 or 963. 
    18 U.S.C. § 3553
    (f). The
    government argued that, because that list does not include any
    provision of the MDLEA, the defendants’ offense was not
    covered. The defendants responded that, because 
    21 U.S.C. § 960
    (b) supplied the penalties for their MDLEA violation, the
    violation qualified as “an offense under” § 960.
    The district court agreed with the government, holding that
    the defendants were ineligible for safety-valve relief. United
    States v. Mosquera-Murillo, 
    172 F. Supp. 3d 24
    , 38 (D.D.C.
    2016). The court thus sentenced each defendant to the
    mandatory-minimum sentence of 10 years. This appeal
    followed.
    II.
    In this appeal, the defendants renew two arguments they
    pressed unsuccessfully in the district court: that the district
    court lacked subject-matter jurisdiction over their prosecutions,
    and that they were eligible for safety-valve relief from the
    10-year mandatory-minimum.
    Despite the defendants’ guilty pleas, they have not waived
    or forfeited either argument. Challenges to a district court’s
    subject-matter jurisdiction can never be waived by plea.
    7
    United States v. Miranda, 
    780 F.3d 1185
    , 1188 (D.C. Cir.
    2015).       Nor can such challenges be forfeited, so
    Moreno-Membache’s failure to contest subject-matter
    jurisdiction in the district court does not preclude him from
    raising the challenge now. And although sentencing challenges
    can be waived, all three defendants entered conditional pleas
    reserving their right to appeal the district court’s determination
    that they were ineligible for safety-valve relief. See 
    id.
     (citing
    Fed. R. Crim. P. 11(a)(2)). We therefore consider both the
    district court’s subject-matter jurisdiction and the defendants’
    safety-valve eligibility.
    A.
    The defendants initially argue that the district court lacked
    subject-matter jurisdiction over their prosecutions. The
    MDLEA criminalizes certain drug-related acts committed “on
    board a covered vessel,” 
    46 U.S.C. § 70503
    (a), as well as
    conspiracies to commit those acts, 
    id.
     § 70506(b). We have
    held that a defendant can violate the Act’s conspiracy provision
    without personally setting foot “on board a covered vessel,” id.
    § 70503(a), so long as a co-conspirator commits a prohibited
    act while “on board a covered vessel” and that act is attributable
    to the defendant under ordinary principles of conspiracy law.
    United States v. Ballestas, 
    795 F.3d 138
    , 145-46 (D.C. Cir.
    2015); see Pinkerton v. United States, 
    328 U.S. 640
    , 647
    (1946).
    The MDLEA defines “covered vessel” to include a vessel
    “subject to the jurisdiction of the United States.” 
    46 U.S.C. § 70503
    (e)(1).       Relatedly, the MDLEA provides that
    “[j]urisdiction of the United States with respect to a vessel . . .
    is not an element of an offense” but is instead a “preliminary
    question[] of law to be determined solely by the trial judge.”
    
    Id.
     § 70504(a). Construing those provisions, we have held that,
    8
    “whether a vessel is ‘subject to the jurisdiction of the United
    States’ is a [question] of subject-matter jurisdiction.” Miranda,
    780 F.3d at 1192.
    In this case, the district court’s subject-matter jurisdiction
    turns on the applicability of 
    46 U.S.C. § 70502
    (c)(1)(C), which
    provides that a vessel is “subject to the jurisdiction of the
    United States”—and thus is a “covered vessel”—if it is
    “registered in a foreign nation [and] that nation has consented
    or waived objection to the enforcement of United States law by
    the United States.” Under the MDLEA, “[c]onsent or waiver
    of objection by a foreign nation to the enforcement of United
    States law by the United States . . . is proved conclusively by
    certification of the [U.S.] Secretary of State or the Secretary’s
    designee.” 
    Id.
     § 70502(c)(2)(B).
    Here, the Secretary’s designee—the Coast Guard’s
    Liaison Officer to the State Department’s Bureau of
    International Narcotics and Law Enforcement Affairs—
    certified that “Colombian authorities confirmed and concurred
    with the United States’ interpretation of Article 16” of the
    treaty between the two countries, “thereby waiving objection
    to the enforcement of United States law by the United States
    over the go-fast vessel MISTBY, all associated contraband, and
    persons on board.” Coast Guard Certification ¶ 4.e. The
    certification concludes that, “[a]ccordingly, the Government of
    the United States determined the go-fast vessel MISTBY was
    subject to the jurisdiction of the United States pursuant to 
    46 U.S.C. § 70502
    (c)(1)(C).” 
    Id. ¶ 4
    .f.
    If, as the certification’s conclusion seems to say, the
    Mistby is “subject to the jurisdiction of the United States
    pursuant to 
    46 U.S.C. § 70502
    (c)(1)(C)” for purposes of all
    MDLEA actions related to the vessel, 
    id.,
     then the district court
    had subject-matter jurisdiction over the defendants’
    9
    prosecutions: in that event, the defendants’ “charged conduct
    [would have] involved . . . one type of vessel ‘subject to the
    jurisdiction of the United States,’” thus giving rise to subject-
    matter jurisdiction, Miranda, 780 F.3d at 1197.
    The defendants argue, however, that the language of the
    certification’s conclusion sweeps more broadly than the scope
    of Colombia’s consent to U.S. jurisdiction. The defendants
    submit that, if a foreign nation “consent[s] or waive[s]
    objection to the enforcement of United States law” over a
    vessel for purposes of proceedings against a specific person or
    item of property, 
    46 U.S.C. § 70502
    (c)(1)(C), then the vessel
    is “subject to the jurisdiction of the United States” for
    proceedings against that person or property—but is not
    “subject to the jurisdiction of the United States” for purposes
    of other MDLEA proceedings. And that, the defendants say, is
    exactly what occurred here.
    The defendants emphasize that, according to the Coast
    Guard’s certification, Colombia “waiv[ed] objection to the
    enforcement of United States law by the United States over the
    go-fast vessel MISTBY, all associated contraband, and persons
    on board.” Coast Guard Certification ¶ 4.e (emphasis added).
    The reference to “persons on board,” the defendants assert,
    means that Colombia denied consent to U.S. jurisdiction over
    the Mistby for purposes of proceedings against persons (like
    the defendants) who were not on board.
    We think the defendants misunderstand the Coast Guard’s
    certification. Assuming the defendants are correct that a
    foreign nation can grant consent to U.S. jurisdiction over a
    vessel for some purposes but deny it for others, and assuming
    also that a district court’s subject-matter jurisdiction under the
    MDLEA would rise or fall correspondingly, we do not read the
    10
    Coast Guard’s certification to indicate that is what happened
    here.
    The certification’s use of the term “persons on board,” 
    id. ¶ 4
    .e, tracks the language of the statute, which discusses its
    “prohibitions” in terms of individuals “on board a covered
    vessel.” 
    46 U.S.C. § 70503
    (a). And the statute, as explained,
    nonetheless reaches land-based co-conspirators because,
    pursuant to “well-established principle[s] of conspiracy law,”
    the acts of a person who is on board the vessel can be attributed
    to a co-conspirator who remains on land. Ballestas, 795 F.3d
    at 145-46. By the same token, the certification’s reference to
    “persons on board” does not exclude persons who remain on
    land: the acts of persons on board the Mistby would be
    attributed to land-based co-conspirators like the defendants,
    such that they too would effectively be considered to have
    committed a prohibited act on board. The indictment
    correspondingly charges the defendants with “conspir[ing],
    and agree[ing] to . . . distribute, and possess with intent to
    distribute,” cocaine and marijuana “on board a vessel subject
    to the jurisdiction of the United States.” United States v.
    Mosquera-Murillo, No. 13-cr-00134-03, Indictment at 2
    (D.D.C. May 9, 2013), ECF No. 1 (emphasis added).
    That is not necessarily to say that a foreign nation is
    incapable of consenting to the enforcement of U.S. law against
    persons on board a vessel without also consenting to the
    enforcement of U.S. law against land-based co-conspirators. In
    theory, a foreign nation could say—and thus a certification
    from the Coast Guard could report—that the nation consented
    to U.S. jurisdiction over a vessel with respect to persons on
    board, but denied consent with respect to co-conspirators not
    on board.
    11
    Here, though, the certification concludes by reporting,
    without qualification, that “the Government of the United
    States determined the go-fast vessel MISTBY was subject to
    the jurisdiction of the United States pursuant to 
    46 U.S.C. § 70502
    (c)(1)(C).” Coast Guard Certification ¶ 4.f. And the
    certification does not indicate that Colombia denied consent
    with respect to any particular class of MDLEA proceedings—
    including proceedings against co-conspirators not on board the
    Mistby. Rather, the certification confirms that Colombia’s
    consent to U.S. jurisdiction encompasses persons on board the
    Mistby, whose conduct on board the vessel is attributable to co-
    conspirators like the defendants.
    As a fallback argument, the defendants suggest that we
    should look behind the Coast Guard’s certification and
    examine Colombian law for ourselves. If we do so, the
    defendants submit, we will find the following: (i) that the
    treaty contemplates the application of U.S. law only if
    Colombia’s domestic law allows for it, T.I.A.S. No. 12,835 art.
    16; and (ii) that Colombian law envisions the application of
    U.S. law only in the case of persons who are “on board” a
    Colombian vessel. Código Penal (Criminal Code) [C. Pen.] tit.
    II, § 217 (Colom.).
    Even assuming, arguendo, that we should scrutinize
    Colombia’s domestic law, we note that one provision of that
    law, introduced by the government in support of subject-matter
    jurisdiction, says that a “punishable act shall be deemed to have
    occurred” in “the place where the effect was produced or
    should have been produced.” Id. § 201. That language mirrors
    the conspiracy-law principle under which a land-based
    conspirator in an enterprise that engages in prohibited conduct
    on board a vessel will be treated as having himself participated
    in the acts on board the vessel.
    12
    Our understanding of the Coast Guard’s certification (and
    of Colombian law) is reinforced by Colombia’s decision to
    grant the United States’ extradition request concerning the
    defendants. If Colombia had in fact intended to deny consent
    to U.S. jurisdiction over the Mistby with respect to proceedings
    against persons who never came on board the vessel, Colombia
    could have given effect to that intention by declining to
    extradite the defendants. Colombia did not do so, however.
    That is not to say that the extradition itself gave rise to
    subject-matter jurisdiction. It is instead to say that the
    extradition fortifies our interpretation of the Coast Guard’s
    earlier certification; and that certification substantiates the
    district court’s subject-matter jurisdiction by demonstrating
    that the Mistby is a “vessel subject to the jurisdiction of the
    United States” for purposes of the defendants’ prosecutions. 
    46 U.S.C. § 70502
    (c)(1).
    In sum, we conclude that Colombia’s waiver of objection
    to U.S. jurisdiction over the Mistby covers the defendants’
    MDLEA prosecutions. The district court therefore had
    subject-matter jurisdiction.
    B.
    The defendants next argue that the district court erred by
    holding that they were ineligible for safety-valve relief from
    the 10-year mandatory-minimum term to which they were
    sentenced. The safety-valve provision is entitled “Limitation
    on applicability of statutory minimums in certain cases.” 
    18 U.S.C. § 3553
    (f). It provides that, “in the case of an offense
    under” one of five enumerated provisions—
    21 U.S.C. §§ 841
    ,
    844, 846, 960, or 963—“the court shall impose a sentence
    pursuant to [the sentencing] guidelines . . . without regard to
    any statutory minimum sentence, if the court finds at
    sentencing” that five specified requirements have been met.
    13
    In these cases, the district court did not reach whether
    those five requirements had been satisfied. Rather, the court
    deemed the defendants ineligible for safety-valve relief at the
    threshold, ruling that they had not been convicted of “an
    offense under” any of the five enumerated provisions. The
    court rejected the defendants’ argument that their cases
    involved “an offense under” one of those provisions, namely
    
    21 U.S.C. § 960
    .
    The sole question we face here is whether the defendants’
    crime is “an offense under” § 960 within the meaning of the
    safety-valve provision. 
    18 U.S.C. § 3553
    (f). Reviewing that
    question of statutory interpretation de novo, see United States
    v. Cordova, 
    806 F.3d 1085
    , 1098 (D.C. Cir. 2015) (per curiam),
    we agree with the defendants: they were convicted of “an
    offense under” § 960, and they therefore satisfy the threshold
    condition for safety-valve eligibility.
    To see why, it is necessary to examine the relationship
    between § 960 and the MDLEA provisions the defendants
    pleaded guilty to violating. The MDLEA prohibits, as relevant
    here, distributing, and possessing with intent to distribute,
    drugs on board a covered vessel. 
    46 U.S.C. § 70503
    (a)(1). A
    separate MDLEA provision prohibits “conspiring to violate
    section 70503,” and establishes that anyone who so conspires
    “is subject to the same penalties as provided for violating
    section 70503.” 
    Id.
     § 70506(b).
    What are those penalties? That is where 
    21 U.S.C. § 960
    comes into play. Under the MDLEA, the first time a person
    violates “paragraph (1) of section 70503(a),” she “shall be
    punished as provided in . . . 21 U.S.C. [section] 960.” 
    46 U.S.C. § 70506
    (a). So the first time a person conspires to
    violate § 70503(a)(1), she likewise “shall be punished as
    provided in . . . 21 U.S.C. [section] 960.” Id. § 70506(a)-(b).
    14
    Because this was the defendants’ first conviction for conspiring
    to violate § 70503(a)(1), § 960 supplied the penalties
    applicable to their crime.
    Does that mean that the defendants’ crime is “an offense
    under” § 960 for purposes of safety-valve eligibility? 
    18 U.S.C. § 3553
    (f). We conclude it does.
    As an initial matter, even if the precise meaning of the
    phrase, “an offense under provision X” could be subject to
    some debate at the margins, there is no doubt about the
    following: a defendant’s case involves “an offense under”
    provision X if the defendant has been convicted of violating
    provision X. So here, there is no dispute that the defendants’
    cases could be described as involving “an offense under” 
    46 U.S.C. §§ 70503
    (a)(1) and 70506(b). Indeed, the government,
    throughout its briefs, describes the defendants as having been
    “convicted of violating the MDLEA” or “violating a provision
    of the MDLEA,” or, equivalently, as having been “convicted
    under the MDLEA” or of “an offense under the MDLEA.”
    E.g., Appellee’s Br. 25, 27, 31-32, 34, 41, 43.
    The defendants’ crime of conviction, though, involved
    more than a violation of (or, equivalently, an offense under) the
    MDLEA. It also involved a violation of (or, equivalently, an
    offense under) 
    21 U.S.C. § 960
    . Offenses are defined by the
    provisions that supply their elements. See Patterson v. New
    York, 
    432 U.S. 197
    , 210 (1977). And here, the defendants’
    offense draws certain elements from the relevant MDLEA
    provisions, 
    46 U.S.C. §§ 70503
    (a)(1), 70506(b), and draws
    other elements from 
    21 U.S.C. § 960
    .
    In particular, the MDLEA supplies the elements that make
    the defendants’ conduct unlawful: (i) conspiring, (ii) to
    intentionally or knowingly, (iii) distribute or possess with
    15
    intent to distribute, (iv) a controlled substance, (v) while on
    board a vessel.        
    46 U.S.C. §§ 70503
    (a)(1), 70506(b).
    Meanwhile, § 960 supplies the offense elements of drug-type
    and drug-quantity—5 or more kilograms of cocaine, and 100
    or more kilograms of marijuana—which bear on the degree of
    culpability and determine the statutory sentencing range. 
    21 U.S.C. § 960
    (b)(1)(B), (b)(2)(G).           In that light, the
    defendants’ crime is “an offense under” both the MDLEA and
    § 960, drawing offense elements from each.
    The understanding that § 960 supplies offense elements
    coheres with the rule of Apprendi v. New Jersey, 
    530 U.S. 466
    (2000). Under Apprendi, “any fact that increases the
    prescribed statutory maximum” penalty to which a defendant
    is exposed amounts to an offense element that “must be
    submitted to a jury, and proved beyond a reasonable doubt.”
    
    Id. at 490
    ; see Alleyne v. United States, 
    133 S. Ct. 2151
    , 2157
    (2013) (plurality). The drug-type and drug-quantity elements
    set out in § 960(b) qualify as elements for purposes of Apprendi
    because they establish the maximum sentence. See 
    21 U.S.C. § 960
    (b)(1)(B)(ii) (“In the case of a violation . . . involving . . .
    5 kilograms or more of . . . cocaine . . . the [defendant] shall be
    sentenced to a term of imprisonment of . . . not more than
    life.”); see also United States v. Fields, 
    251 F.3d 1041
    , 1043
    (D.C. Cir. 2001). And because the drug-type and drug-quantity
    criteria in § 960 constitute some of the elements of the
    defendants’ offense (with the other elements supplied by the
    MDLEA), their cases involve “an offense under” § 960 for
    purposes of safety-valve eligibility. 
    18 U.S.C. § 3553
    (f).
    As further confirmation that § 960 supplies elements of the
    defendants’ offense, the government’s indictment charged the
    defendants with violating both the MDLEA and § 960, not just
    the former. Specifically, the indictment charged the defendants
    with one count of conspiring to distribute, and possess with
    16
    intent to distribute, 5 or more kilograms of cocaine and 100 or
    more kilograms of marijuana on board a covered vessel, “all in
    violation of Title 46, United States Code, Sections 70503 and
    70506(b)” and “Title 21, United States Code, Sections
    960(b)(1)(B) and (b)(2)(G).” United States v. Mosquera-
    Murillo, No. 13-cr-00134-03, Indictment at 2 (D.D.C. May 9,
    2013), ECF No. 1 (emphasis added).
    To the same effect, the government’s plea agreement with
    each of the defendants stated that the defendant “agrees to
    plead guilty” to the charged conduct just described, once again
    “in violation of Title 46, United States Code, Sections 70503
    and 70506(b)” and “Title 21, United States Code, Sections
    960(b)(1)(B) and (b)(2)(G).” E.g., United States v. Mosquera-
    Murrillo, No. 13-cr-00134-03, Plea Agreement at ¶ 1 (D.D.C.
    Jan. 20, 2016), ECF No. 185. The judgments against the
    defendants therefore pronounce that they were “adjudicated
    guilty” of the charged offense in violation of both the relevant
    MDLEA provisions and § 960(b). E.g., United States v.
    Mosquera-Murillo, No. 13-cr-00134-03, Judgment at 1
    (D.D.C. Aug. 1, 2016), ECF No. 250.
    Despite the government’s indictment and plea agreements
    describing the defendants as having violated § 960, the
    government now submits that the defendants were not
    convicted of “an offense under” § 960 for purposes of
    safety-valve eligibility. The government points out that § 960
    consists of two subsections. The first, subsection (a), lists
    certain “unlawful acts” by reference to drug offenses set out
    elsewhere in the code—e.g., “bring[ing] or possess[ing] on
    board a vessel, aircraft, or vehicle a controlled substance”
    “contrary to section 955.” 
    21 U.S.C. § 960
    (a)(2). The second
    subsection, subsection (b), sets out the penalties for the
    offenses listed in subsection (a) based on drug-type and
    drug-quantity—e.g., “[i]n the case of a violation of subsection
    17
    (a)” involving “1 kilogram or more of . . . heroin,” the “person
    committing such violation shall be sentenced to a term of
    imprisonment of not less than 10 years and not more than life.”
    
    21 U.S.C. § 960
    (b)(1)(A).
    According to the government, the safety-valve provision’s
    reference to “an offense under” § 960 means only those
    specific offenses listed in § 960(a)—not other offenses defined
    in part by the drug-type and drug-quantity elements set out in
    § 960(b). And because no MDLEA offense is listed in
    § 960(a), the government argues, the defendants’ cases do not
    involve “an offense under” § 960 within the meaning of the
    safety-valve provision.
    The government’s reading of the safety-valve provision is
    unpersuasive. The statute speaks in terms of an “offense
    under” § 960 without limitation—not an offense under only
    § 960(a). Plus, the structure of § 960 demonstrates that the
    defendants’ crime qualifies as “an offense under” § 960 no less
    than the crimes listed in § 960(a).
    Subsection (a) of § 960 does not lay out any element of—
    and thus does not define in whole or in part—any criminal
    offense. Instead, § 960(a) merely lists certain offenses
    established elsewhere in the code. It does so for one reason: to
    identify a set of offenses for which § 960(b) supplies the
    drug-type and drug-quantity elements, and, accordingly, the
    range of potential penalties.
    The MDLEA offense of which the defendants were
    convicted interacts with § 960(b) in exactly the same way as
    the offenses listed in § 960(a). Just as those offenses are
    established outside of § 960 and “shall be punished as provided
    in subsection (b)” of § 960, id. § 960(a), the MDLEA also
    establishes offenses outside of § 960, which likewise are
    18
    punished under the penalty scheme set out in § 960(b). Indeed,
    the MDLEA uses precisely the same wording in linking certain
    of its offenses to § 960(b) as § 960(a) does in linking its listed
    offenses to § 960(b): the MDLEA states that, for first-time
    offenders of 
    46 U.S.C. § 70503
    (a)(1), the defendant “shall be
    punished as provided in” § 960. 
    46 U.S.C. § 70506
    (a).
    Compare 
    id.,
     with 
    21 U.S.C. § 960
    (a).
    If both the offenses listed in § 960(a) and the relevant
    offenses under the MDLEA are (i) established outside of § 960,
    and (ii) make use of the drug-type and drug-quantity elements
    and associated penalties set forth in § 960(b), then there is no
    reason to conclude—as the government would—that the
    former qualify as “offenses under” § 960 for purpose of
    safety-valve eligibility whereas the latter do not. Nothing in
    the statutory text supports drawing such a distinction. Rather,
    just as a person who commits one of the offenses listed in
    § 960(a) violates both the provision establishing the offense
    (e.g., 
    21 U.S.C. § 955
    ) and § 960(b), the defendants in these
    cases violated both the MDLEA and § 960(b).                 The
    government was right to describe the defendants’ offenses in
    that manner in the indictment and plea agreements.
    In addition, treating the defendants as having violated
    § 960, and thus as eligible for safety-valve relief, would align
    with Congress’s nearly unbroken pattern of setting identical
    penalties for drug crimes committed in domestic waters and
    drug crimes committed on the high seas. When Congress
    criminalized opium possession on the high seas in 1914, it set
    the maximum penalty at two years, which at the time was the
    maximum penalty for importing opium into the United States.
    Act of Jan. 17, 1914, Pub. L. No. 63-46, §§ 2, 4, 
    38 Stat. 275
    ,
    276. In 1922, Congress simultaneously raised the maximum
    penalties for both offenses from two to ten years. Narcotic
    Drugs Import and Export Act, Pub. L. No. 67-227, § 2(c), 42
    
    19 Stat. 596
    , 596 (1922). Then, in 1951, Congress simultaneously
    decreased the maximum penalties for both offenses from ten to
    five years. Boggs Act, Pub. L. No. 82-255, § 2(c), 
    65 Stat. 767
    ,
    767 (1951).
    In 1970, Congress overhauled the drug code, repealing the
    statutes that define the offenses discussed above, and
    establishing a new prohibition—codified at 
    21 U.S.C. § 955
    —
    against importing drugs via the customs waters of the United
    States. Comprehensive Drug Abuse Prevention and Control
    Act of 1970, Pub. L. No. 91-513, § 1007, 
    84 Stat. 1236
    , 1288.
    Congress provided that the penalties applicable to that offense
    were those set forth in 
    21 U.S.C. § 960
    . 
    Id.
     § 1010, 84 Stat. at
    1290. Shortly thereafter, Congress enacted what is now known
    as the MDLEA, including its prohibition against possession
    with intent to distribute on the high seas. Pub. L. No. 96-350,
    § 1, 
    94 Stat. 1159
    , 1159 (1980). And Congress provided that
    § 960 also supplied the penalties for that offense. Id. § 1(g)(1),
    94 Stat. at 1159.
    In light of the century-long pattern of identical penalties
    for drug offenses committed in domestic waters and on the high
    seas, it is notable that, as both parties agree, offenders who
    violate § 955 are eligible for safety-valve relief. 
    21 U.S.C. § 960
    (a) (listing violations of § 955 as offenses punishable
    under § 960(b)). So if offenders who violate the MDLEA were
    ineligible for safety-valve relief, then, by enacting the
    safety-valve provision, Congress would have broken its
    100-year pattern of penalty parity. We do not understand
    Congress to have done so.
    Two other circuits have considered whether MDLEA
    offenses penalized under § 960(b) qualify as “offenses under”
    § 960 for purposes of the safety-valve provision. Both courts
    have concluded that such offenses do not qualify. See United
    20
    States v. Pertuz-Pertuz, 
    679 F.3d 1327
    , 1329 (11th Cir. 2012)
    (per curiam); United States v. Gamboa-Cardenas, 
    508 F.3d 491
    , 496 (9th Cir. 2007). We respectfully reach the opposite
    conclusion. Neither of those decisions expressly assesses
    whether the drug-type and drug-quantity facts supplied by
    § 960(b) constitute offense elements, such that an MDLEA
    offender penalized under § 960(b) should be considered
    someone who has violated both the MDLEA and § 960. That
    consideration, as we have explained, is pivotal to our
    conclusion.
    Our decision today, we note finally, does not necessarily
    resolve whether the safety valve covers a different provision to
    which both parties have directed our attention: 
    21 U.S.C. § 860
    .      In defining the offense of “[d]istribution or
    manufacturing in or near schools and colleges,” § 860
    incorporates both the unlawful-act elements of 
    21 U.S.C. § 841
    (a) and the drug-type and drug-quantity elements of
    § 841(b). So one could argue that a violation of § 860 is an
    “offense under” § 841, in which case offenders who violate
    § 860 would be eligible for safety-valve relief, given that the
    safety valve lists § 841 as a covered provision. That said, § 860
    restates in full the unlawful-act elements of § 841(a), and then
    modifies the penalties prescribed by § 841(b) by doubling or
    tripling them. That might mean that all the elements of an
    § 860 violation are supplied by § 860 itself, rather than by a
    combination of § 860 and § 841. If that is the case, then
    offenders who violate § 860 would be ineligible for safety-
    valve relief, given that the safety valve does not list § 860 as a
    covered provision. We need not decide the issue now; we
    simply note that today’s decision does not necessarily answer
    the § 860 question either way.
    21
    *    *   *    *   *
    For the foregoing reasons, we vacate the defendants’
    sentences and remand for resentencing, at which the district
    court should consider whether the defendants meet the five
    remaining safety-valve requirements.
    So ordered.
