Importers Sue as $50 Billion in Tariff Refunds Stays Unpaid

Customs and Border Protection has accepted over $121 billion in IEEPA tariff refund claims but paid just $71 billion. The Supreme Court struck down the underlying tariff authority without creating an automatic refund process. Rivian sued the U.S. government on July 23, 2026, seeking repayment with interest — a route other importers may follow as the backlog grows.
