On May 26, 2017, the U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed a judgment from the U.S. Court of International Trade (CIT) which held that the government was entitled to interest on unpaid duties under 19 U.S.C. § 580 (statutory 6% against sureties) from the date of CBP’s first formal demand and §1505(d) (variable interest rate against importers and sureties) up to the amount of the bond. It also held that a surety company or importer wishing to challenge the interest must file a protest with U.S. Customs and Border Protection (CBP), just as in any decision for a charge or exaction by CBP. Additionally the CAFC upheld the CIT’s decision to not award equitable interest, as being at the court’s discretion. U.S. v. American Home Assurance Company (Slip Op. 2016-1088, 2016-1090 May 26, 2017).
