MEMORANDUM **

Abdul Razzaq M. Daas appeals his 63-month sentence, imposed following our remand in United States v. Daas, 198 F.3d 1167, 1180-81 (9th Cir. 1999). Daas was convicted of distributing ephedrine and pseudoephedrine with reasonable cause to believe they would be used to manufacture methamphetamine, in violation of 21 U.S.C. § 841(d)(2) (1998). We have jurisdiction under 28 U.S.C. § 1291 and 18 U.S.C. § 3742, and we affirm.

Daas first contends that the district court erred because, in departing downward based on a sentencing disparity between similarly situated co-defendants, it refused to consider a disparity created by his co-defendants’ U.S.S.G. § 5K1.1 departure for substantial assistance. This *529contention is unavailing, because we lack jurisdiction to review the extent of a downward departure. United States v. Riggins, 40 F.3d 1055, 1058 (9th Cir. 1994).

Daas next contends that the district court failed, on resentencing, to consider the factors set forth in 18 U.S.C. § 3553(a). We decline to address this contention, because the scope of our remand was limited to the sole issue of a downward departure based on sentencing disparity. See United States v. Pimentel, 34 F.3d 799, 800 (9th Cir. 1994) (per curiam) (concluding that, because scope of remand was limited to single sentencing issue raised in prior appeal, district court was without authority to reexamine any other sentencing issues on remand).

AFFIRMED.
