Tariff Refund Act of 2026

S 3905, the Tariff Refund Act of 2026, requires U.S. Customs and Border Protection (CBP) to refund all duties unlawfully collected under the International Emergency Economic Powers Act (IEEPA) to importers within 180 days of the bill's enactment, including interest. It mandates CBP to reliquidate previously processed imports to calculate refunds and prioritizes small businesses for faster processing, with coordinated outreach to them via the Small Business Administration. The bill also requires CBP to submit regular reports to Congress detailing refund progress and timelines. This directly affects importers who paid IEEPA duties, with specific provisions to streamline refunds for small business importers.
