BOUDIN, Circuit Judge, BOWNES, Senior Circuit Judge, and STAHL, Circuit Judge.
STAHL, Circuit Judge.
Pursuant to a plea agreement with the government, defendant-appellant Frank J. Lindia pleaded guilty to a one-count indictment charging that, from December 1994 to January 31, 1995, he and codefendants John C. Mosby and Augustine T. Aguirre conspired to possess with intent to distribute in excess of fifty kilograms of marijuana, in violation of 21 U.S.C. § 846, 841(a)(1) and (b)(1)(C). On appeal, Lindia claims that the district court erred by: including a negotiated but unconsummated sale of 150 pounds of marijuana in the sentence calculation; sentencing him as a career offender; and refusing to depart downward from the sentence on his claim that the career-offender criminal history category significantly overrepresented his past criminal conduct.
I.
Pertinent Background and Prior Proceedings
A Facts
We accept the facts as set forth in the uncontested portions of the Presentence In-vestígatíon Report (“PSR”) and the sentencing hearing transcript,
see United States v. Muniz,
49 F.3d 36, 37 (1st Cir.1995), reciting additional facts below as necessary.
In late 1994, federal and Maine law enforcement authorities, with the help of a cooperating individual (Cl), began investigating Lindia’s activities. Soon thereafter, the Cl (who had been the “buyer” in monitored marijuana transactions) introduced to Lindia an “associate,” undercover DEA Special Agent Mike Cunniff, who would handle further transactions. During the ensuing negotiations, Agent Cunniff was introduced to Lindia’s associates, Aguirre and Mosby.
On January 20, 1995, Agent Cunniff met Mosby at Mosby’s home in Jamestown, Rhode Island, where Mosby delivered to Cunniff forty-eight pounds of marijuana. On January 31, 1995, Lindia and Aguirre met Agent Cunniff in Portland, Maine, to receive payment for the marijuana. The meeting took place in a hotel room that government agents had previously set up with videotape equipment. During the meeting, Agent Cun-niff delivered $62,400 in cash and commented on the failure of Aguirre and Lindia to accept the payment earlier, as they had promised. Concerned about his customer’s unhappiness, Lindia apologized for the delay and indicated that more marijuana was available. The three men then planned for an additional thirty pounds of marijuana to be delivered the next day.
Also during the videotaped meeting, Lin-cha told Cunniff, “We have something else ... that we would like to send up to you.” Both Lindia and Aguirre then spoke of a subsequent shipment of marijuana and indicated that they could probably send Cunniff “about” 150 or 200 pounds, depending upon the capacity of the vehicle in which it would travel.
Lindia stated that the lot could be
delivered in a little over one week’s time. After counting out the cash payment for the forty-eight pound lot and discussing details of the next day’s thirty-pound delivery, Lin-cha and Aguirre left the hotel room and were promptly arrested. Lindia eventually pleaded guilty and cooperated with the authorities.
B. Sentencing
The district court sentenced Lindia as a career offender under 28 U.S.C. § 994(h), including as a predicate offense Lindia’s Rhode Island conviction on a
nolo contendere
plea for possession with intent to deliver marijuana. Under the Career Offender guideline, U.S.S.G. § 4B1.1, the court was required to determine the offense statutory maximum in order to ascertain the applicable offense level. Because the court included the negotiated 150-pound lot in the amount of drugs attributable to Lindia, it found the offense statutory maximum to be twenty years’ imprisonment under 21 U.S.C. § 841(b)(1)(C).
Pursuant to the Career Offender guideline, the statutory maximum of twenty years yielded an offense level of thirty-two with a criminal history category of VI. Lindia asked the court to depart downward on the basis that the criminal history category overrepresented his criminal history; but the court refused, specifically ruling that it did not have the authority to do so. The court did grant a three-level downward adjustment in the offense level for acceptance of responsibility, resulting in a total offense level of twenty-nine and a guideline imprisonment range of 151 to 188 months. On the government’s motion under U.S.S.G. § 5K1.1, the court departed downward from the guideline range for Lindia’s substantial assistance and imposed a sentence of 108 months’ incarceration.
II.
Discussion
We review the sentencing court’s findings of fact for “clear error” and generally defer to its credibility determinations.
United States v. Muniz,
49 F.3d 36, 41 (1st Cir.1995);
United States v. Whiting,
28 F.3d 1296, 1304 (1st Cir.),

de novo
the court’s interpretation of the guidelines and application of law.
Muniz,
49 F.3d at 41.
A
Drug Quantity Calculation
The extent of the penalty for a controlled-substance conviction is determined in large part by the amount of drugs properly attributable to the defendant.
United States v. Campbell,
61 F.3d 976, 982 (1st Cir.1995),
cert. denied,
— U.S. —, 116 S.Ct. 1556, 134 L.Ed.2d 657 (1996). On appeal, Lindia challenges the district court’s inclusion of the negotiated but unconsummated 150-pound lot in the calculation of his sentence. Without this quantity, he would have received the benefit of 21 U.S.C. § 841(b)(1)(D), which provides for a maximum imprisonment term of only five years “[i]n the case of less than 50 kilograms of marijuana.”
Use of this penalty provision would have yielded, under the Career Offender guideline, a pre-adjustment offense level of seventeen instead of thirty-two.
See
U.S.S.G. § 4B1.1.
The PSR stated that Lindia was responsible for 103.5 kilograms of marijuana, representing a combination of the forty-eight pound, thirty-pound, and 150-pound lots.
Lindia objected to this conclusion, asserting,
inter alia,
that the 150-pound lot “never existed” and was not the object of any conspiracy, and that his statements about it constituted mere “puffing” in an attempt to gain Agent Cunniffs business confidence. At the sentencing hearing, Lindia testified that the 150-pound lot had never been previously discussed or planned and that no steps had been taken to obtain it. Lindia repeated that the discussion was meant to impress Agent Cunniff, and testified that only after obtaining payment for the forty-eight and thirty-pound lots did he intend to actually seek the additional 150 pounds of marijuana.
The district court found, under a preponderance-of-the-evidence standard, that the proposed delivery of the 150 pound lot had not been discussed or planned before the videotaped meeting. The court also found, however, that based on Lindia’s and Aguirre’s statements, the 150 pounds of marijuana added to, and were part of, the charged conspiracy. The court found that Lindia and Aguirre intended to produce that marijuana and were reasonably capable of doing so and thus, the 150 pounds were includable in the offense conduct for the purposes of the statutory maximum and the Sentencing Guidelines.
Application note 12 of U.S.S.G. § 2D1.1 provides:
In an offense involving negotiation to traffic in a controlled substance, the weight under negotiation in an uncompleted distribution shall be used to calculate the applicable amount. However, where the court finds that the defendant did not intend to produce and was not reasonably capable of producing the negotiated amount, the court shall exclude from the guideline calculation the amount that it finds the defendant did not intend to produce and was not reasonably capable of producing.
We have interpreted this note as requiring the sentencing court to include the negotiated amount in the drug quantity calculation unless it finds both that the defendant did not have the intent to produce the amount, and that he lacked the capacity to deliver it.
United States v. Wihbey,
75 F.3d 761, 777 (1st Cir.1996);
Muniz,
49 F.3d at 39. Application note 12 applies for the purposes of both the Sentencing Guidelines and the statutory penalties under 21 U.S.C. § 841(b).
Muniz,
49 F.3d at 39-40 (indicating that five-year difference in statutory mandatory minimum was dependent upon drug quantity calculated under application note 12);
United States v. Pion, 25
F.3d 18, 25 n. 12 (1st Cir.) (noting that drug quantity finding under note 12 provides threshold calculus for mandatory mínimums),
cert. denied,
— U.S. —, 115 S.Ct. 326, 130 L.Ed.2d 286 (1994).
Lindia contends that due process requires the government to prove drug quantity beyond a reasonable doubt. Drug quantity, however, is not an element of the offense of conviction, 21 U.S.C. §§ 846 and 841(a)(1), but is typically relevant only for determining the penalty.
See
21 U.S.C. § 841(b);
United States v. Campbell,
61 F.3d 976, 979-80 (1st Cir.1995) (citing
United States v. Lam Kwong-Wah,
966 F.2d 682, 685 (D.C.Cir.),
cert. denied,
506 U.S. 901, 113 S.Ct. 287, 121
L.Ed.2d 213 (1992));
United States v. Patterson,
38 F.3d 139, 143-44 (4th Cir.1994),
cert. denied,
— U.S. —, 115 S.Ct. 1968, 131 L.Ed.2d 858 (1995). As such, drug quantity for purposes of § 841(b) is determined by the sentencing court under a preponderanee-of-the-evidence standard.
See United States v. Barnes,
890 F.2d 545, 551 n. 6 (1st Cir.1989) (noting that court, not jury, determines drug quantity under § 841(b)),
cert. denied,
494 U.S. 1019, 110 S.Ct. 1326, 108 L.Ed.2d 501 (1990);
United States v. Lombard,
72 F.3d 170, 175-76 (1st Cir.1995) (explaining that “once convicted, a defendant has no right under the Due Process Clause to have his sentencing determination be confined to facts proved beyond a reasonable doubt,” rather, applicable standard is preponderance of the evidence);
Whiting,
28 F.3d at 1304 and n. 5 (reaffirming preponderant evidence standard);
see also McMillan v. Pennsylvania,
477 U.S. 79, 91-93, 106 S.Ct. 2411, 2418-20, 91 L.Ed.2d 67 (1986).
Here, to assist in its determination of whether the conspiracy included the 150-pound lot, the district court had the benefit of the videotape of the hotel meeting and Lindia’s own testimony at the sentencing hearing. The transcript from the hotel meeting clearly reveals Lindia’s (and Aguirre’s) stated desire and agreement to provide Cunniff with 150 to 200 pounds of marijuana. The discussion included details such as the identification of the shipment’s source, the capacity of the vehicle to transport the marijuana, and the number of days for delivery. Thus, there was sufficient, reliable evidence from which the court could find, by a preponderance of the evidence, that the conspiracy included the 150-pound lot.
To invoke the exception of application note 12, the court needed to be persuaded that Lindia did not have the intent and ability to produce the 150-pound lot.
Wihbey,
75 F.3d at 777. The court was free to reject, as it did, Lindia’s claim that the discussion of the 150 pounds was mere “puffing” to impress the buyer into future negotiations.
See Whiting,
28 F.3d at 1305 (refusing to disturb sentencing court’s rejection of “puffing” claim);
see also United States v. DeMasi,
40 F.3d 1306, 1322 n. 18 (1st Cir.1994) (noting that sentencing court’s choice
between supportable plausible inferences cannot amount to clear error),
cert. denied,
— U.S. —, 115 S.Ct. 947, 130 L.Ed.2d 890 (1995). Lindia did not prove to the court that he lacked the intent and ability to produce the negotiated amount; rather, based on the evidence presented, the court affirmatively found that he had both. We discern no clear error in the court’s finding that the 150 pounds of marijuana were part of the conspiracy and, as such, were includa-ble under U.S.S.G. § 2D1.1 to determine the offense statutory maximum and Guideline sentencing range.
B. Career Offender Status
The district court sentenced Lindia as a career offender under 28 U.S.C. § 994(h) due to two previous drug distribution offenses and the instant offense.
See
U.S.S.G. § 4B1.1. Lindia challenges this aspect of his sentence, arguing first, that conspiracy to commit a controlled substance offense should not trigger career offender status, and second, that the court should not have counted as a predicate offense a Rhode Island charge to which Lindia pleaded
nob contendere.
1. Conspiracy
As
Predicate Offense
In 1994, this court joined a number of our sister circuits in holding that, in U.S.S.G. § 4B1.2, comment, (n. 1), the Commission properly designated
conspiracy
to commit a “crime of violence or a controlled substance offense” as a triggering or predicate offense for career offender purposes, even though conspiracy convictions are not listed in the body of the pertinent guidelines or in 28 U.S.C. § 994(h).
United States v. Piper,
35 F.3d 611, 618-619 (1st Cir.1994) (citing cases),
cert. denied,
— U.S. —, 115 S.Ct. 1118, 130 L.Ed.2d 1082 (1995). On appeal, Lindia invites us to reconsider
Piper
and join those circuits holding that conspiracies to commit the crimes defined in § 994(h) do not fall within its purview.
See e.g., United States v. Mendoza-Figueroa,
28 F.3d 766 (8th Cir.1994),
cert. denied,
— U.S. —, 116 S.Ct. 939, 133 L.Ed.2d 864 (1996). We decline the invitation and adhere to our controlling precedent, thus affirming the use of the instant conspiracy conviction to trigger the career offender provisions.
2. The Rhode Island Nob Contendere Plea
In 1986, Lindia pleaded
nob conten-dere
to a Rhode Island charge of possession with intent to deliver marijuana (“the 1986 charge”). On this plea, the state court adjudged Lindia “guilty as charged and convicted” and gave him a deferred sentence. Lin-cha argues that the 1986 charge is not a “conviction” under Rhode Island law and therefore cannot constitute a predicate offense for purposes of career offender status.
We have previously addressed the issue of whether or not a
nob contendere
plea and subsequent disposition in Rhode Island constitutes a “conviction” for federal sentencing purposes.
See United States v. Patrone,
948 F.2d 813, 816-17 (1st Cir.1991),
cert. denied,
504 U.S. 978, 112 S.Ct. 2953, 119 L.Ed.2d 575 (1992).
Patrone
involved sentencing under the armed-career-eritninal statute, 18 U.S.C. § 924(e), which specifically provides that
state
law determines whether or not a state disposition constitutes a “conviction.”
Id.
at 816;
see
18 U.S.C. § 921(a)(20). By contrast, for purposes of the career offender provisions, whether or not a state disposition constitutes a “conviction” is determined by reference to federal law and the Guidelines.
See United States v. Pierce,
60 F.3d 886, 892 (1st Cir.1995) (analyzing Guidelines provisions in concluding that state disposition on
nolo contendere
plea constituted “conviction”),
petition for cert. filed,
(Oct. 19, 1995) (No. 95-6474).
After carefully analyzing the Guideline language and commentary, we held in Pierce that the guilt-establishing event, such as a guilty plea, trial, or plea of nolo
contendere,
“determines whether and when there has been a countable ‘conviction’” for purposes of the Career Offender guideline. 60 F.3d at 892. We concluded that a Florida offense, to which the defendant pleaded
nolo contendere
and that resulted in a “withheld adjudication,” constituted a countable “conviction” under the Career Offender guideline.
Id
Similarly, Lindia’s
nolo contendere
plea, subsequent adjudication, and deferred sentence also constitute a “conviction” for career offender purposes.
See also United States v. Cuevas,
75 F.3d 778, 780-83 (1st Cir.1996) (holding, under federal standards, that Rhode Island disposition on
nolo contendere
plea is a “conviction” for immigration law purposes).
Moreover, there is little doubt that the 1986 charge would constitute a conviction under Rhode Island law. In
Patrone,
we explained that under R.I.Gen.Laws § 12-18-3(a), a
nolo contendere
plea will not constitute a “conviction for any purpose” if the court places the defendant on probation and the defendant completes probation without violating its terms. 948 F.2d at 816, n. 1. Section 12-18-3(b) further provides, however, that subdivision (a) “shall not apply to any person who is sentenced to serve a term in the adult correctional institution or who is given a suspended or deferred sentence in addition to probation.” As explained in
Pa-trane,
we interpret this provision to mean that a
nolo contendere
plea followed by a deferred sentence (or other sentence described in § 12 — 18—3(b)) constitutes a “conviction” under Rhode Island law.
See id.
Lindia contends that our analysis in
Patrone
is inapplicable, reading much into § 12-18-3(b)’s language: “or deferred sentence
in addition to probation.”
(emphasis added). Lindia claims that he was not placed on “probation” for the 1986 charge, rather, he “entered probationary status based solely on an agreement with the Rhode Island Attorney General.” The record before this court is less than clear on this issue. It is apparent, however, that although Rhode Island law provides for a special circumstance in which a
nolo contendere
plea and successful completion of probation will not constitute a conviction, that circumstance will not apply where the defendant is also given a sentence of imprisonment, or a suspended or deferred sentence.
See
R.I. Gen. Laws § 12-18-3. Thus, even assuming that Lindia was not placed on probation, the controlling fact is that he was given a deferred sentence, thus rendering the benefits of § 12-18-3(a) inapplicable. Lindia cites to no other applicable Rhode Island law in which a
nolo contendere
plea will not constitute a conviction.
Under both federal and state law standards, the district court properly counted Lindia’s 1986 charge as a conviction for purposes of the career offender adjudication.
C. Authority to Depart Doumward Based on Overrepresentation in Career-Offender Criminal History Category
Lindia contends that the criminal history category of VI, calculated pursuant to his career offender status, significantly overre-presents his criminal history. The district court ruled that nothing in the career-offender statute, 28 U.S.C. § 994(h), or in the Guidelines permitted a downward departure on this basis.
The First Circuit has not yet decided the permissibility of such a departure in a career offender case,
see United States v. Morrison,
46 F.3d 127, 129 (1st Cir.1995), although many of our sister circuits have answered this question in the affirmative,
see e.g., United States v. Spencer,
25 F.3d 1105 (D.C.Cir.1994);
United States v. Rogers,
972 F.2d 489 (2d Cir.1992);
United States v. Bowser,
941 F.2d 1019 (10th Cir.1991);
United States v. Lawrence,
916 F.2d 553, 554 (9th Cir.1990).
Pursuant to the Sentencing Reform Act of 1984, commencing at 18 U.S.C. § 3551, 28 U.S.C. §§ 991-998 (as amended), the United States Sentencing Commission promulgates Sentencing Guidelines that establish presumptive sentencing ranges for categories of defendants and offenses.
Williams v. United States,
503 U.S. 193, 195-96, 112 S.Ct. 1112, 1116-17, 117 L.Ed.2d 341 (1992). Under 28 U.S.C. § 994(h),
The Commission shall assure that the guidelines specify a sentence to a term of imprisonment at or near the maximum term authorized for categories of defendants in which the defendant is eighteen years old or older and [has been convicted of a violent crime or felony drug offense and has a least two such prior convictions].
This statute is meant to ensure that the Commission’s Guidelines provide that certain felony-recidivists receive maximum authorized sentences.
See United States v. LaBonte,
70 F.3d 1396, 1404 (1st Cir.1995). The Career Offender guideline, U.S.S.G. § 4B1.1, is the Commission’s implementation of § 994(h).
See
U.S.S.G. § 4B1.1, comment, (backg’d);
LaBonte,
70 F.3d at 1400-1401. The guideline establishes the career-offender presumptive sentencing range by setting forth enhanced total offense levels — by reference to offense statutory máximums
— and provides that “[a] career offender’s criminal history category in every case shall be Category VI,” the highest category level. U.S.S.G. § 4B1.1.
The Sentencing Reform Act permits a sentencing court to depart from a Guidelines’ presumptive sentencing range “only when it finds that ‘there exists an aggravating or mitigating circumstance of a kind, or to a degree, not adequately taken into consideration by the Sentencing Commission in formulating the guidelines.’ ”
Williams,
503 U.S. at 198, 112 S.Ct. at 1118 (quoting 18 U.S.C. § 3553(b));
see also
28 U.S.C. § 991(b)(1)(B) (providing that the Commission’s purposes include “maintaining sufficient flexibility to permit individualized sentences when warranted by mitigating or aggravating factors not taken into account in the establishment of general sentencing guidelines”). Accordingly, the Guidelines provide that “a case that falls outside the linguistically applicable guideline’s ‘heartland’ is a candidate for departure.”
United States v. Rivera,
994 F.2d 942, 947 (1st Cir.1993);
see
U.S.S.G. Ch. I, Pt.
A,
intro, comment. (4)(b). Such cases are deemed “unusual,” and, by definition, the Commission (with some exceptions) has not “adequately” considered them within the meaning' of § 3553(b).
Id.
As Justice (then Chief Judge) Breyer thoroughly explained in
Rivera,
the exceptions to this principle are those several factors the Commission has explicitly rejected as permissible grounds for departure.
Id.
at 948-949 (also explaining that encouraged departures are likely “reasonable” while discouraged departures require “unusual or special” circumstances);
see also Williams,
503 U.S. at 200, 112 S.Ct. at 1119 (concluding that departure based on expressly rejected factor constitutes incorrect application of Guidelines).
The Application Instructions for the Guidelines, set forth in U.S.S.G. § 1B1.1, explain that after a sentencing court determines the offense level, the defendant’s criminal history category, and the applicable guideline range, it then refers to certain provisions for “Specific Offender Characteristics and Departures” and “any other policy statement or commentary in the guidelines that might warrant consideration in imposing sentence.” A guidelines policy statement, U.S.S.G. § 4A1.3, specifically addresses the adequacy of a criminal-history category’s reflection of a defendant’s past criminal conduct.
See also,
U.S.S.G. Ch. 5, Pt. H, intro, comment, and § 5H1.8 (stating that criminal history is relevant in determining if sentence should be outside applicable guideline range). Section 4A1.3 explicitly recognizes that a defendant’s criminal history category may “significantly over-represent[ ] the seriousness of a defendant’s criminal history or the likelihood that the defendant will commit further crimes.” U.S.S.G. § 4A1.3, (policy statement). In such cases, the sentencing court may consider a downward departure.
Id.
We agree with our sister circuits (that have considered the issue) that a sentencing court may invoke § 4A1.3 to depart downward from the career-offender category if it concludes that the category inaccurately reflects the defendant’s actual criminal history, within the meaning of 18 U.S.C. § 3553(b).
See e.g., United States v. Spencer,
25 F.3d 1105, 1113 (D.C.Cir.1994);
United States v. Rogers,
972 F.2d 489, 494 (2d Cir.1992);
United States v. Bowser,
941 F.2d 1019, 1024 (10th Cir.1991);
United States v. Lawrence,
916 F.2d 553, 554-55 (9th Cir.1990).
The district court interpreted Congress’s mandate in § 994(h) and the Commission’s implementation, U.S.S.G. § 4B1.1, as precluding departure on the basis of overrepresentation in all eases in which the defendant is assigned a criminal history category of VI under the Career Offender guideline. Section 994(h), however, is directed to the Commission’s duty to formulate guidelines pertaining to categories of defendants, not to sentencing courts faced with individual defendants. As explained above, Congress and the Commission have rejected rigid sentencing schemes by empowering the sentencing court to consider factors that might comprise an “unusual” case. The Commission has not designated as a “forbidden departure” the overrepresentation of a criminal history category in career offender cases,
see Rivera, 994 F.2d
at 948-49, and “there is nothing unique to career offender status which would strip a sentencing court of its ‘sensible flexibility' in considering departures.”
Rogers,
972 F.2d at 493.
A district court that considers numerous Guidelines cases has a “special competence” to determine the “ordinariness” or “unusualness” of a particular case.
Rivera,
994 F.2d at 951. When faced with a departure motion in a career-offender case, as in other eases, the court’s experience and unique perspective will allow it to decide if the ease before it falls outside the guideline’s “heartland,” warranting departure.
See Rivera,
994 F.2d at 952 (holding that appellate court reviews “unusualness” determination with “respect” for sentencing court’s “superi- or ‘feel’ for the case” (citation omitted)). Because the district court in this case did not consider whether or not the career-offender criminal history category overrepresented Lindia’s circumstances, so as to make his case “unusual,” we remand for its determination of this issue.

For the foregoing reasons, we
