19 CFR § 182.50 - Liquidation and payment of drawback claims.
(a) General. When the drawback claim has been fully completed by the filing of all required documents, and exportation of the articles has been established and the amount of duties paid to Canada or Mexico has been established, the entry will be liquidated to determine the proper amount of drawback due either in accordance with the limitation on drawback set forth in § 182.44 of this subpart or in accordance with the regular drawback calculation. The liquidation procedures of subpart H of part 190 of this chapter, as appropriate, will control for purposes of this subpart.
(c) Accelerated payment. Accelerated drawback payment procedures will apply as set forth in § 190.92 of this chapter, as appropriate. However, a person who receives drawback of duties under this procedure must repay the duties paid if a USMCA drawback claim is adversely affected thereafter by administrative or court action.
