Nhan Kiem Tran (“Tran”), federal prisoner # 48684-079, appeals the district court’s denial of his 18 U.S.C. § 3582 motion to reduce his sentence based on amendment 640 to the sentencing guidelines.

Amendment 640 to U.S.S.G. § 2Dl.l(a)(3) is not listed in U.S.S.G. § lB1.10(c). Therefore, this amendment may not be applied retroactively to reduce Tran’s sentence. See United States v. Drath, 89 F.3d 216, 217-18 (5th Cir. 1996). Tran has not shown that the court abused its discretion in denying his motion for a modification of sentence. The judgment of the district court is AFFIRMED.
