SUMMARY ORDER

Defendant-Appellant Ronald Tuttle appeals from the judgment of the United States District Court for the Western District of New York (Geraci, convicting and sentencing him to four concurrent terms of 97 months’ imprisonment and three years of supervised release for conspiracy to possess with intent to distribute a substance containing 3, 4-methylenedio-xypyrovalerone (“MDPV”), a Schedule I controlled substance (Count I), see 21 U.S.C. § 846, conspiracy to import into the United States MDPV (Count II), see 21 U.S.C. § 963, importing into the United States a substance containing MDPV (Count III), see 21 U.S.C. §§ 952(a), 960(a), and 960(b)(3), and attempting to possess with intent to distribute a substance containing MDPV (Count IV), see 21 U.S.C. § 846.

Tuttle challenges (1) the district court’s jury instructions as to Counts I and II in light of the Supreme Court’s decision in McFadden v. United States, — U.S.-, 135 S.Ct. 2298, 192 L.Ed.2d 260 (2015), which held that to convict a defendant of distributing an analogue drug, the Government must prove the defendant’s knowledge that the drug was covered under the Controlled Substance Analogue Enforcement Act of 1986 (“Analogue Act”), 21 U.S.C. §§ 802, 813, (2) the district court’s jury instructions as to Counts III and IV, given that MDPWs status as a controlled substance was ‘in flux’ during the time period covered by the evidence, and (3) the sufficiency of the evidence supporting his conviction on Counts III and IV. In rejecting each of these challenges, we assume the parties’ familiarity with the underlying facts, the procedural history of the case, and the issues on appeal.

1. Counts I and II of the Jury Charge

Tuttle argues the district court erred when it failed to charge the jury on the criminal intent required for the underlying offenses. This Court reviews an unobjected to jury charge for plain error. United States v. George, 779 F.3d 113, 117 (2d Cir. 2015). 1 Plain error exists where (1) there is an error (2) that is clear or obvious, rather than subject to reasonable dis *122 pute, and the error (3) affects the appellant’s substantial rights and (4) seriously affects the fairness, integrity, or public reputation of judicial proceedings. United States v. Sanchez, 773 F.3d 389, 391 (2d Cir. 2014). A challenged instruction is not viewed in isolation but in context “to determine whether considered as a whole, the instructions adequately communicated the essential ideas to the jury.” United States v. Sabhnani 599 F.3d 215, 237 (2d Cir. 2010) (internal quotation omitted).

Tuttle contends that the district court’s jury instructions did not comply with the Supreme Court’s ruling in McFadden v. United States, — U.S.-, 135 S.Ct. 2298, 192 L.Ed.2d 260 (2015), which held that in prosecutions under the Analogue Act the Government must prove a defendant knew he was dealing with a substance regulated under the Analogue Act. However, Tuttle’s conviction was not under the Analogue Act. Tuttle was charged with conspiracy and substantive offenses related to MDPV, a Schedule I controlled substance as of October 21, 2011. See Schedules of Controlled Substances: Temporary Placement of Three Synthetic Cathinones Into Schedule I, 76 Fed.Reg. 65371, 65371 (Oct. 21, 2011) (to be codified at 21 C.F.R. pt. 1308). All of the charged conspiracy and other unlawful conduct concerned periods after that date. McFadden is therefore inapposite.

As McFadden is inapposite, Tuttle has failed to demonstrate any error, much less plain error, with respect to Counts I and II.

2. Counts III and TV of the Jury Charge

As with Counts I and II, Tuttle made no objections to Counts III and IV at trial and so we review them for plain error. George, 779 F.3d at 117. With respect to Counts III and IV, the substantive counts, Tuttle contends that the jury instructions were erroneous because they failed to instruct in accordance with McFadden when the evidence covered a period before MDPV was listed on Schedule I. He argues, “[t]he court should have required the jury to make a finding that Mr. Tuttle knew the specific drug analogue that he was dealing with.” Appellant Br. 36. This argument has no merit. As we noted above, MDPV was listed on .Schedule I during the period covered by Tuttle’s indictment. The Analogue Act was therefore irrelevant to the jury’s deliberations. Tuttle has failed to demonstrate any error in the jury instructions for Counts III and IV, much less plain error.

3. Sufficiency of the Evidence

Tuttle contends that the evidence produced at trial was insufficient to prove beyond a reasonable doubt that he knowingly imported MDPV from China and knowingly attempted to possess with intent to distribute MDPV. This Court reviews de novo challenges to sufficiency of the evidence. United States v. Rangolan, 464 F.3d 321, 324 (2d Cir. 2006). The evidence is viewed in the light most favorable to the government and will be affirmed if “any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.” United States v. Aguilar, 585 F.3d 652, 656 (2d Cir. 2009) (internal quotation marks omitted). “Assessments of witness credibility and choices between competing inferences lie solely within the province of the jury.” United States v. Payne, 591 F.3d 46, 60 (2d Cir. 2010). Where conflicts in the testimony exist, we must defer to the jury’s resolution as to the weight of evidence and credibility of the witnesses. Id.

*123 There was more than sufficient evidence for any rational juror to find that Tuttle knowingly imported MDPV from China and attempted to possess with intent to distribute MDPV. The evidence adduced at trial included (1) testimony from a special agent with Homeland Security Investigations (“HSI”) that Tuttle accepted a package for delivery in 2013 that had contained MDPV, (2) testimony of Michael Garinger, an inmate at a state correctional facility, that he had purchased MDPV from Tuttle for almost two years prior to February 2013, (3) Tuttle’s own statement made to an HSI agent that he was ordering MDPV from China, (4) emails from Tuttle’s account to various suppliers in China explicitly referencing orders of and prices for MDPV, and (5) handwritten notes with price quotes for various amounts of MDPV found in Tuttle’s home. While Tuttle argues his own testimony at trial contradicted this evidence, it was within the province of the jury to disbelieve his testimony and credit competing inferences. Payne, 591 F.3d at 60. We will not disturb the jury’s reasonable credibility determinations on appeal.

We have considered Tuttle’s remaining arguments and find them to be without merit. Accordingly, we AFFIRM the judgment of the district court.
