The fallout from U.S. tariffs struck down by the Supreme Court in February 2025 is widening on two fronts: the government is appealing a Court of International Trade order that would extend refunds beyond the companies that sued, while shippers including FedEx, UPS and DHL have started passing reimbursements to customers who directly paid import charges and consumers are suing retailers and Japanese companies over whether broader tariff-related costs should also be returned. The tariffs, imposed by President Donald Trump in 2025 under the International Emergency Economic Powers Act, have already led U.S. Customs and Border Protection to process and certify about $100 billion in refunds, with roughly $166 billion in broader reimbursements under way. FedEx said it has begun returning $800 million, UPS said it paid $5 billion in tariffs on behalf of clients and sought $500 million in an initial phase, and DHL said it has filed claims for almost all eligible shipments where it was importer of record. At the same time, class-action and consumer suits against companies including Toyota Motor, Fast Retailing, Nintendo, Sony Group, Costco, Nike, Amazon and Walmart are testing whether companies that passed tariffs into prices can keep any refunds. Defendants argue consumers will struggle to prove how much of a price reflected tariffs or tie any later refund to a specific purchase.
