    UNITED STATES of America, Appellee, v. Gerson NUNGARAY-BELTRAN, also known as La Grande, Appellant.
    No. 02-1930.
    United States Court of Appeals, Eighth Circuit.
    Submitted Feb. 28, 2003.
    Decided March 11, 2003.
    Before BOWMAN, MURPHY, and RILEY, Circuit Judges.
   PER CURIAM.

After Gerson Nungaray-Beltran (Nungaray-Beltran) pled guilty to conspiring to distribute and possess with intent to distribute more than 500 grams of a substance containing methamphetamine, in violation of 21 U.S.C. §§ 841(a)(1), (b)(1), and 846, the district courtWest’s N.C.G.S.A. § l-l sentenced him to 145 months imprisonment and 5 years supervised release. On appeal, counsel moved to withdraw and filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). Nungaray-Beltran filed a pro se supplemental brief arguing the district court erred in applying a firearm enhancement and in denying him safety-valve relief. He also argues: (1) the government failed to prove whether the drugs underlying his offense were 1 or d-methamphetamine, or whether they were methamphetamine at all; (2) the Attorney General improperly reclassified methamphetamine in powder form from a Schedule III to a Schedule II controlled substance; and (3) counsel was ineffective at sentencing. After careful review of the record, we affirm.

We reject Nungaray-Beltran’s arguments for reversal. The firearm enhance-merit was proper, as firearms were found with drug-packaging materials both at Nungaray-Beltran’s residence and at his rental house. See U.S.S.G. § 2D1.1, cmt. n. 3; United States v. Cave, 293 F.3d 1077, 1079 (8th Cir.2002) (standard of review); United States v. Jones, 195 F.3d 379, 383-84 (8th Cir.1999). As a result, safety-valve relief was preempted. See U.S.S.G. § 501.2(a)(2).

Further, section 841(b) does not differentiate between 1 and d-methamphetamine, see United States v. Maza, 93 F.3d 1390, 1400 n. 4 (8th Cir.1996), cert. denied, 519 U.S. 1138, 117 S.Ct. 1008, 136 L.Ed.2d 886 (1997); Nungaray-Beltran acknowledged in his plea agreement he was pleading guilty to a charge involving 500 grams or more of “methamphetamine”; and laboratory reports introduced at sentencing reflected the substance in question was methamphetamine, see United States v. Hyatt, 207 F.3d 1036, 1037-38 (8th Cir. 2000). Finally, Congress has given the Attorney General authority to transfer drugs from one schedule to another regardless of the drug’s initial placement, see 21 U.S.C. §§ 811(a)(1) and 812(c), and the ineffective-assistance claim is not properly before us, see United States v. Martin, 59 F.3d 767, 771 (8th Cir.1995).

Accordingly, we grant counsel’s motion to withdraw, and we affirm. 
      
      . The Honorable Warren K. Urbom, United States District Judge for the District of Nebraska.
