Derwayne Williams pleaded guilty to conspiring to distribute crack cocaine. The district court 1 relied upon a prior Missouri felony drug conviction to find *257 that Williams was subject to the twenty-year mandatory-minimum-sentence provision of 21 U.S.C. § 841(b)(1)(A). The court then imposed the statutory minimum sentence. Williams appeals arguing his pri- or state conviction cannot be used for enhancement purposes because the Missouri courts suspended imposition of his sentence, and under Missouri law, the suspended sentence is not a final judgment. He also argues he received ineffective assistance of counsel.

Federal law, and not state law, governs for the purpose of determining whether a prior conviction is final and triggers application of the statutory minimum contained in § 841(b)(1)(A). United States v. Craddock, 593 F.3d 699, 701 (8th Cir. 2010). We recently applied this rule to affirm the identical enhancement based on a Missouri conviction involving the suspended imposition of a sentence. Id (finding pursuant to federal law that a Missouri felony drug conviction qualifies as a “prior conviction” for purposes of § 841(b)(1)(A) even though the Missouri courts had suspended imposition of the sentence). Accordingly, the district court properly found that Williams’s state-law conviction triggered the enhancements of § 841(b)(1)(A). 2

We affirm the judgment of the district court.
