The purpose of this legislation, known as the Tariff Refund Act of 2026, is to ensure that individuals and businesses receive refunds for duties that were unlawfully imposed under the International Emergency Economic Powers Act. This follows a Supreme Court ruling that deemed these duties illegal. Key provisions of the Act include a requirement for the Commissioner of U.S. Customs and Border Protection to process refunds within 180 days of the law's enactment. This refund will include interest and applies to all importers of goods that were subject to these unlawful duties.
