This case requires us to consider what constitutes a “mixture or substance containing a detectable amount” of a controlled substance for purposes of sentencing. Pursuant to a plea agreement, defendant Juan Berroa-Medrano (“Ber-roa”) pled guilty to a single count of conspiracy to distribute heroin, but reserved the right to challenge at sentencing the weight of the heroin in question. At sentencing, although one of the two packages Berroa admitted to distributing contained mostly drug cutting agents and only trace amounts of heroin, the court used the total weight of the two packages as the basis to sentence Berroa to a 100-month prison term. On appeal, Berroa challenges the sentence on the grounds that the court improperly considered the gross weight of the two packages, about 1 kilogram, rather than the net weight of the heroin itself. Because we conclude that the District Court was entitled to consider the entire weight of any mixture or substance that contained a trace amount of heroin, we affirm.
*279 I.
A.
The facts of this case are fairly straightforward. Berroa entered into an agreement with his co-defendant Mustafa Al-abed to sell an undetermined amount of heroin to an individual who was actually a confidential informant. On October 28, 1997, the informant, equipped with a wireless transmitter, met with Alabed to arrange for the purchase of one kilogram of heroin.
The Informant and Alabed met inside Alabed’s carpet store in Philadelphia, and then, to complete the transaction, walked across the street to a building that Al-abed was renovating. Inside the building, the two men met Berroa, who was holding a cereal box. Berroa handed the box to the informant, who opened it and found that it contained two separately wrapped packages, one large and one small, each containing an off-white substance that appeared to be heroin. The informant inspected the packages without removing the contents, and returned the box to Berroa, asking the defendants whether the heroin was from the same batch as a sample that had been given to him earlier in the day by Alabed.. Alabed assured him that it was. The informant left the building, ostensibly to retrieve the payment for the heroin, but instead informed the drug enforcement agents of what had transpired. When he informed them that he believed Berroa was carrying a gun, the agents decided to wait for backup. Before backup arrived, however, Berroa fled the scene.
Once the backup officers arrived, Alabed was arrested and the cereal box containing the two packages of off-white powder was seized. The larger of the packages, which was approximately the size and shape of a kilo of heroin, was field-tested by the agents with negative results for the presence of heroin. However, the smaller package, which was on top of the larger one inside the cereal box, field-tested positive for heroin. The smaller package contained slightly more than one ounce of off-white powder. Subsequent laboratory analysis disclosed that the larger package weighed slightly less than one kilogram (983.9 grams) and was comprised almost exclusively of procaine and lidocaine, common heroin cutting agents. The lab also determined that the larger package contained traces of heroin, but the purity of the drug could not be determined due to its small quantity. The smaller package, weighing 32 grams, contained a similar mix of cutting agents, but with heroin detected at a purity of 3%.
B.
On December 3, 1997, a federal grand jury indicted Berroa, in absentia, along with Alabed, and charged him with conspiracy to distribute heroin in violation of 21 U.S.C. § 846; distribution of heroin in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2; and distribution of heroin near a school in violation of 21 U.S.C. §§ 860(a) and 841(a)(1). 1 Berroa was further charged with using and carrying a firearm in connection with a drug trafficking offense in violation of 18 U.S.C. § 924(c). Berroa was arrested approximately one year later in December 1998, in Camden, New Jersey, on state criminal charges unrelated to the instant case. Thereafter, he was removed to the Eastern District of *280 Pennsylvania to face the federal indictment.
On February 22, 1999, Berroa pled guilty, pursuant to a written plea agreement, to a single count of a superseding information charging distribution of heroin in violation of 21 U.S.C. § 841(a)(1). 2 The plea agreement provided for dismissal of the remaining charges. Additionally, Ber-roa’s plea agreement contained a provision stating that the parties “have not agreed on the quantity of drugs on which the defendant’s sentence should be calculated under[the relevant sentencing guidelines], and reserve their right to present their respective positions to the Court and Probation Department.” App. Br. at 4.
On May 2, 2001, the District Court sentenced Berroa. The District Court concluded that under the United States Sentencing Guidelines, the entire contents of each package must be included in calculating Berroa’s sentence. The court therefore determined that Berroa’s offense conduct involved more than one kilogram of heroin, and that, accordingly, Berroa’s sentencing guideline range was ' 168-210 months. However, because of the unusually low purity of the drug, the court granted Berroa a downward departure under U.S.S.G. § 2D1.1(b)(6), and sentenced him to 100 months imprisonment, 5 years supervised release, and a fine of $2,500. 3 Berroa timely appealed.
II.
We have jurisdiction to review Berroa’s sentence pursuant to 28 U.S.C. § 129Í. We review de novo a district court’s application of the Sentencing Guidelines.
United States v. Henry,
III.
A.
The District Court calculated Berroa’s sentence using the Drug Quantity Table, subsection (c) of U.S.S.G. § 2D1.1. 4 Application Note (A) of the “Notes to Drug Quantity Table” provides that, “[u]nless otherwise specified, the weight of a controlled substance set forth in the table refers to the entire weight of any mixture *281 or substance containing a detectable amount of the controlled substance” U.S. Sentencing Guidelines Manual § 2Dl.l(c), cmt. n.A. (emphasis added). The language is derived from the mandatory minimum sentence provision of the statute under which Berroa was convicted. Section 841(b) provides minimum penalties for anyone violating § 841(a), including “100 grams or more of a mixture or substance containing a detectable amount of heroin” 21 U.S.C. § 841(b)(1)(B)® (emphasis added). The District Court examined this language and determined that, under the circumstances of Berroa’s case, it was required to include the combined weight of both packages in calculating Berroa’s sentence. The judge commented that, although it was “unusual” in his experience that a lab was “unable to determine the purity of [the drug in question,]” he could not “ignore [that] ... [t]here was a detectable amount of a [controlled] substance” in the larger package. App. at A46. Therefore, the court determined that Berroa’s base offense level, including a 2-step increase for obstruction of justice based on a false identity charge, was 34, resulting in a guideline range of 168-210 months imprisonment. 5
The District Court was not without precedent in deciding to include the entire contents of the larger, highly adulterated package in sentencing Berroa. For example, this Court recently determined that, even when a drug contains a very slight amount of a controlled substance, the entire package must count toward a defendant’s sentence.
See United States v. Butch,
The Supreme Court has observed that since the terms “mixture” and “substance” have “not been defined in the statute or the Sentencing Guidelines and [have] no distinctive common-law meaning,” they should be “construed ... to have their ordinary meaning.”
Neal v. United States,
Like the LSD and blotter paper in Chapman, the traces of heroin in the package used to sentence Berroa were diffused within the procaine and lidocaine, and the heroin could neither be distinguished nor easily separated from the contents of the package. Thus, the entire contents of the larger of the two packages used to sentence Berroa appears to satisfy the criteria identified by the Chapman court for identifying a “mixture” or a “substance.”
Nevertheless, Berroa attempts to distinguish his case from
Chapman
by relying on this court’s decision in
United States v. Rodriguez,
Berroa argues that, like the defendants in Rodriguez, he did not actually intend to sell a kilo of heroin to the informant, but rather meant to “rip him off’ by selling him a highly diluted “gag bag.” He claims that the immeasurably small amount of heroin in the larger package proves this intent. Therefore, he concludes that as in Rodriguez, the sentencing court should not consider the weight of the non-controlled substances in calculating his sentence.
However, Berroa’s reading of this Court’s holding in Rodriguez is too narrow. In Rodriguez, this Court placed as much emphasis on the plain meaning of the term “mixture,” in the context of that case, as it did on the intent of the seller. The Rodriguez court observed that, unlike the circumstances in Chapman, in their case: 1) the boric acid and the cocaine remained distinct although in close proximity; 2) the boric acid was not being used as a cutting agent; 3) the boric acid, being highly toxic, was not intended to be consumed; and, 4) the boric acid did not facilitate the distribution of cocaine. Id. at 1004-05. Relying on these characteristics, we concluded that the combination of cocaine and boric acid did not constitute a “mixture or substance” as contemplated by the Sentencing Commission in promulgating § 2D1.1, and that the clear intent of the seller was to use the cocaine “only to effectuate the scam by masking the identity of the boric acid blocks.” Id. at 1006.
Berroa’s case is clearly distinguishable. First, the trace of heroin in the larger package was not “distinct although in close
*283
proximity,” but instead was inextricably combined with the procaine and lidocaine. Second, while Berroa may argue that the procaine and the lidocaine in the larger package were not truly used as cutting agents but simply used to trick the buyer into buying a “gag bag,” procaine and lido-caine are among the most common cutting agents for street heroin.
See Hurtado v. United States,
Alternatively, Berroa argues that, even if the larger package constituted a “mixture or substance,” it was not a “consumable,” “marketable,” or “ingestible” mixture of the type that numerous courts have determined that Congress and the Guidelines intended to punish.
See Rodriguez,
We disagree. In analyzing the cases upon which he relies, Berroa ignores the single, factor that was common to the determination of each: that in order for the substance in question to be marketable, ingestible, and/or consumable, either the distributor or the dealer first had to separate the controlled substance from the additional material.
See Rodriguez,
Conversely, common cutting agents such as procaine and lidoeaine are added to heroin specifically to facilitate its use by addicts — thereby improving its ingestibility — and to increase its profitability for dealers and distributors — thereby enhancing its marketability. Because it was aware of this, Congress “clearly intended [that a] dilutant, cutting agent, or carrier medium be included in the weight of [drugs like heroin and cocaine] for sentencing purposes” even though “[i]n some cases, the concentration of the drug is very low.”
Chapman,
Berroa makes a related argument that a ‘trace’ of heroin is not a ‘detectable amount’ under the Guideline. Only one Circuit appears to have held that an infinitesimally small portion of controlled substance combined in a mixture with common cutting agents should not be considered under the Sentencing Guidelines.
See United States v. Jackson,
Finally, we note Berroa’s argument that a downward departure is warranted because the unusually low purity of the heroin involved here places the case outside the heartland of cases covered under the guidelines. However, the District Court in fact granted Berroa a significant departure, finding that to do otherwise would “shock the conscience.” App. at A 46. As we previously mentioned, in sentencing Berroa, the court first arrived at a Guideline sentencing range of 168-210 months, but then granted Berroa a substantial departure for “low drug purity” under U.S.S.G. § 2Dl.l(b)(6). This departure resulted in a sentencing reduction of over 5 years. Berroa’s 100-month sentence, based on a mixture containing a very low amount of controlled substance, might appear inequitable. Yet the Court accounted for this concern. The Court’s sizeable downward departure for low drug purity mitigates any perceived unfairness here. 7
Accordingly, we hold that the traces of heroin disclosed during lab testing in this case, although in amounts too small to determine its purity within a mixture, constitute a detectable amount, and that the District Court did not err when it included the entire weight of the larger package in calculating Berroa’s sentence under U.S.S.G. § 2D1.1.
IV.
For the foregoing reasons, the judgment of the District Court is affirmed.
Notes
. Alabed later pled guilty to a single count of distribution of heroin, in violation of 21 U.S.C. § 841(a)(1), and was sentenced to 60 months imprisonment followed by a five-year term of supervised release.
. 21 U.S.C. § 841(a)(1) states, in relevant part, that “it shall be unlawful for any person knowingly or intentionally ... to manufacture, distribute, or dispense, or [to] possess with intent to manufacture, distribute, or dispense, a controlled substance."
. Application Note 9 to U.S.S.G. § 2D1.1 specifically indicates that an upward departure may be appropriate where the controlled substance is of an unusually high purity. The comment further explains that the purity of a controlled substance, "particularly in the case of heroin, may be relevant in the sentencing process because it is probative of the defendant’s role or position in the chain of distribution." Given the Sentencing Commission's omission of any discussion of a
downward
departure for
low
drug purity, some courts have decided that a downward departure is permissible while others have disagreed.
Compare United States v. Mikaelian, 168
F.3d 380, 390 (9th Cir.1999) (stating that "the low purity of heroin involved in a crime cannot be categorically excluded as a basis for a downward departure”),
with United States v. Upthegrove,
In this case, the Government acknowledged the District Court's discretion to depart downward based on low purity and does not challenge the exercise of the Court's discretion in this regard on appeal. Gov't Br. at 28-29 & n.10. Accordingly, we need not reach this issue here.
.U.S.S.G. § 2D1.1 establishes the base offense level for offenses involving the "Unlawful Manufacturing, Importing, Exporting, or Trafficking” of controlled substances, and includes possession with the intent to commit these felonies.
. Conversely, if the court had decided to include only the contents of the smaller package, or even the contents of the smaller package along with the net weight of the heroin in the larger package, Berroa’s base offense level, considering his criminal history category of II, would have been 18. Even with a 2-step increase for obstruction of justice, Ber-roa’s sentence would have been significantly reduced to 30-37 months.
. "Gag bag” is street parlance for a highly diluted or completely fake container of drugs. Gov’t Br. at 14-15.
. As we previously noted, supra at n. 3, the Government acknowledged the District Court’s discretion to depart downward based on low drug purity and does not challenge the court's discretionary authority in this regard . on appeal.
