Defendant Mansour Saikaly appeals the 240-month sentence of incarceration imposed for his conviction on one count of conspiracy to traffic in cocaine, arguing that the sentence violates the rule announced in Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). Because we find Saikaly’s sentence comports with the rule of Apprendi as explained in Harris v. United States, 536 U.S. 545, 122 S.Ct. 2406, 153 L.Ed.2d 524 (2002), we will affirm the sentence.
BACKGROUND
This is the third incarnation of Mr. Saikaly’s appeal to this court. Our opinion today includes only the procedural and factual background material to this appeal; the entire procedural and factual history underlying this action is reported at United States v. Saikaly, 207 F.3d 363 (6th Cir.2000). In April of 1993, Saikaly was convicted by a jury on one count of conspiracy to distribute and possess with the intent to distribute cocaine, in violation of 21 U.S.C. § 846, as well as two counts of unlawful possession of a weapon in violation of 18 U.S.C. § 922(g) and on one count of using and carrying firearms during and in relation to the drug conspiracy offense in violation of 18 U.S.C. § 924(c). Finding that Saikaly was responsible for more than five but less than fifteen kilograms of cocaine, that he was an armed career criminal, pursuant to USSG § 4B1.4, and that his criminal history category was V, the district court sentenced him to a total of 360 months in prison. On appeal, this court affirmed Saikaly’s conviction and sentence. See United States v. Ross, Nos. 93-3772, 93-3880, 93-3901, 93-3915, 93-3916, 93-4040, 93-4198, 1995 WL 253183, 1995 U.S.App. LEXIS 9955 (6th Cir. April 27,1995).
Saikaly then filed a motion to vacate, set aside or correct his sentence pursuant to 28 U.S.C. § 2255, arguing, among other things, that his conviction under 18 U.S.C. § 924(c) for the possession or use of a firearm in the furtherance of a drug crime was invalid under Bailey v. United States, 516 U.S. 137, 116 S.Ct. 501, 133 L.Ed.2d 472 (1995), and that his counsel, both at trial and on appeal, were ineffective because they failed to object to his classification as an armed career criminal. The district court granted Saikaly’s Section 2255 motion on those two grounds and ordered a new sentencing hearing. The new presentence report prepared by the probation department found, among other things, that the amount of cocaine the government attributed to Saikaly was more than five but less than fifteen kilograms, resulting in a base offense level of thirty-two under the Sentencing Guidelines; however, the report noted that Saikaly attributed to himself only 2.5567 kilograms (the total amount listed in the overt acts set out in the indictment), which would result in a base offense level of twenty-eight. Saikaly objected to the new presentence report, specifically challenging-for the first time-the amount of cocaine attributed to him. The district court declined to recalculate or change the drug quantity, inasmuch as that issue had not been raised on prior appeal or in the Section 2255 motion, and sentenced Saikaly to a term of 240 months’ imprisonment.1
*389On appeal, a split panel of this court held that the district court had erred in refusing to consider Saikaly’s objections to the drug quantity contained in the presentence report. See Saikaly, 207 F.3d at 370. We remanded the case for further consideration of Saikaly’s sentence. While Saikaly’s case was before the district court on remand, the Supreme Court issued its opinion in Apprendi.
On remand, the case was assigned to District Court Judge Polster, following the retirement of District Court Judge Bell, who had presided over all prior proceedings. Before Judge Polster, Saikaly filed a motion based solely on Apprendi, objecting to his sentence on the grounds that the drug quantity had not been determined by the jury, and demanding that the conviction on the drug conspiracy charge be vacated, or that he be released from custody on the basis of the time he had already served, or that he be granted a new trial. Judge Polster, while considering Saikaly’s objections to the amount of cocaine attributed to him, struggled to apply two decisions from this court: United States v. Ramirez, 242 F.3d 348 (6th Cir.2001) (applying Apprendi and holding that a defendant convicted under 21 U.S.C. § 841(a)(1) for an unspecified quantity of drugs must be sentenced under 21 U.S.C. § 841(b)(1)(C), which has no mandatory minimum sentence), and In re Michael A. Clemmons, 259 F.3d 489 (6th Cir.2001) (holding that Apprendi does not apply retroactively to cases on collateral review). The district court concluded that although the matter was before it on collateral review-and hence Apprendi did not apply-nonetheless, because after Apprendi, drug quantity is a factual issue that must be proven beyond a reasonable doubt, “it would be impermissible under Apprendi for the court to make a factual assessment of the quantity of drugs attributable to Saikaly.” Accordingly, the district court held, “the only appropriate course of action is to let Judge Bell’s initial decision on drug quantity stand. There is, therefore, a mandatory minimum sentence that must be imposed, so the sentence of 240 months remains in place.” Saikaly filed a timely notice of appeal and the district court granted a certificate of appealability.
ANALYSIS
We first note that this case comes before us as a direct appeal and not on collateral review,2 and consideration of the Apprendi issue is therefore appropriate. Saikaly complains on appeal that the district court failed to comply with our instructions on remand to consider Saikaly’s objections to the drug quantities attributed to him by the presentence report, and, instead, simply adopted Judge Bell’s original determination of drug quantity and reimposed the resulting minimum sentence under 21 U.S.C. § 841(b)(1)(A). Saikaly argues that the district court should have sentenced *390him under 21 U.S.C. § 841(b)(1)(C), the “default” provision for the lowest detectable drug quantity, which carries no mandatory minimum sentence, and by failing to do so, the district court violated the rule in Apprendi. We review de novo a defendant’s claim that his sentence violates his constitutional rights under Apprendi. United States v. Lloyd, 10 F.3d 1197, 1220 (6th Cir.1993).
Saikaly relies upon our opinion in United States v. Ramirez, 242 F.3d 348 (6th Cir.2001). which held that any aggravating factors, such as drug quantity, “that increase the penalty from a nonmandatory minimum sentence to a mandatory minimum sentence, or from a lesser to a greater minimum sentence, are now elements of the crime to be charged and proved.” Id. at 351-52. Under this rule, the district court would have erred by sentencing Saikaly-with an aggravating sentencing factor of five kilograms of eocaine-to the statutory minimum of twenty years under 21 U.S.C. § 841(b)(1)(A). However, the Supreme Court, in Harris v. United States, 536 U.S. 545, 122 S.Ct. 2406, 153 L.Ed.2d 524 (2002), effectively overruled Ramirez as it applied to mandatory minimum sentences. See United States v. Leachman, 309 F.3d 377, 383 (6th Cir.2002). This court’s recent opinion in United States v. Copeland, 304 F.3d 533 (6th Cir.2002), amended by 321 F.3d 582 (6th Cir.2003), directly addresses the question presented in the case at bar. In Copeland, we held that:
while Harris does not alter this court’s well-established principle that, where drug quantity is not proved beyond a reasonable doubt, a defendant’s sentence cannot exceed the statutory range set forth in § 841(b)(1)(C), Harris does modify our prior holdings such that a defendant cannot demonstrate an Apprendi violation where he has been sentenced to a term of years encompassed by § 841(b)(1)(C). Thus, where a defendant is made subject to a higher range of punishment under §§ 841(b)(1)(A) and (B) but is nonetheless sentenced within the confines of § 841(b)(1)(C), his rights under Apprendi are not violated.
Copeland, 321 F.3d at 603 (italics in original).
Even if the district court erred in failing to follow our instruction that it consider Saikaly’s objections to the presentence report’s finding of drug quantity, that error is patently harmless. Judge Polster addressed Saikaly’s objections — which, as we have pointed out, were based solely on Apprendi — as we instructed the court to do on remand. In any event, however, there is no Apprendi error in the present case. Saikaly argues only Apprendi: “BY VIRTUE OF APPRENDI. A STATUTORY MANDATORY MINIMUM SENTENCE SPECIFIED IN EITHER § 841(B)(1)(A) OR § 841(B)(1)(B) CANNOT MANDATE A PRISON SENTENCE THAT EXCEEDS THE HIGHEST SENTENCE TO WHICH THE DEFENDANT WOULD OTHER WISE HAVE BEEN EXPOSED....” Appellant’s Reply Brief at ii, 1. Saikaly does not contest the fact that when he committed the instant offense, he already had a final prior conviction for a felony drug offense. 21 U.S.C. § 841(b)(1)(C) therefore requires that he be sentenced to a term not to exceed thirty years’ (360 months’) imprisonment. The district court sentenced him to 240 months’ imprisonment, a term manifestly within the confines of § 841(b)(1)(C). Saikaly’s sentence does not violate the rule in Apprendi, which is the only issue raised on appeal.
CONCLUSION
For the foregoing reasons, we AFFIRM the sentence imposed by the district court.
. A person convicted of violating 21 U.S.C. § 846 (conspiracy) is “subject to the same penalties as those prescribed for the offense, the commission of which was the object of the attempt or conspiracy.” Accordingly, Saikaly was sentenced under the general scheme of 21 U.S.C. § 841. Under 21 U.S.C. § 841(b)(1)(A), a person committing a drug offense involving five kilograms or more of cocaine faces a mandatory minimum sentence of twenty years if such person commits the violation after a prior conviction for a felony *389drug offense becomes final. Because Saikaly had already been convicted of a felony drug offense, and the court had attributed five kilograms of cocaine to Saikaly, his mandatory minimum sentence was 240 months.
. The district court’s attempt to apply In re Clemmons, its holding that Apprendi does not apply retroactively to cases on collateral review, and its issuance of a certificate of appealability are inapposite here. The matter was before Judge Polster on remand after Judge Bell had granted Saikaly’s Section 2255 motion, vacated his initial sentence and imposed a new sentence, which Saikaly appealed. Saikaly’s appeal of that sentence was a direct appeal, and this court’s remand for consideration of Saikaly’s objections to the new presentence report was outside the context of his Section 2255 petition. Accordingly, there was no need for a Certificate of Appealability in this case because Saikaly’s Section 2255 petition had previously been granted. See 28 U.S.C. § 2253(c); Fed. R.App. P. 22(b).
