A significant victory for American businesses arrived Wednesday as a federal judge ruled companies are legally entitled to refunds for tariffs previously struck down by the Supreme Court. Judge Richard Eaton of the U.S. Court of International Trade declared that all importers who paid these duties are now “entitled to the benefit” of the high court’s decision.
The ruling stemmed from a case brought by Atmus Filtration, a Tennessee-based company, but its implications are far-reaching. Judge Eaton has designated himself as the sole judge to oversee all cases concerning these tariff refunds, streamlining the process for potentially thousands of claimants.
Over 1,000 companies, including household names like Costco and FedEx, have already filed lawsuits seeking to recover the substantial costs imposed by the tariffs. This wave of litigation underscores the financial burden these duties placed on businesses across the nation.
The foundation for these potential refunds was laid last month when the Supreme Court, in a 6-3 decision, invalidated President Donald Trump’s broad tariffs on goods from nearly every country. The court found that Trump had exceeded his authority by utilizing the International Emergency Economic Powers Act (IEEPA) to impose these tariffs.
While the Supreme Court’s initial ruling didn’t directly address the issue of refunds, the financial implications are enormous. Estimates from the Penn Wharton Budget Model suggest the total value of potential refunds could reach a staggering $175 billion.
Data from U.S. Customs and Border Protection reveals the federal government collected $134 billion in duties under IEEPA up until the end of 2025. This substantial sum now hangs in the balance, awaiting the outcome of the refund claims.
A coalition of small businesses, “We Pay the Tariffs,” hailed the judge’s decision as a crucial win. Their executive director, Dan Anthony, stated the ruling confirms the right of businesses to reclaim “billions in unlawful tariffs,” expressing concern that the government might delay the refund process.
Adding to the potential relief for businesses, a court filing from the previous administration indicated that any validated refunds would include interest. This detail, revealed by a senior official in U.S. Customs and Border Protection, offers a further benefit to those seeking reimbursement.
However, the path to receiving these refunds may not be swift. The Customs and Border Protection office noted a “review period” will be necessary to ensure compliance with all customs laws and to verify no other outstanding duties or fees exist.
While many companies stand to benefit, Canadian firms were largely shielded from these IEEPA tariffs due to a specific exemption within the Canada-U.S.-Mexico Agreement on trade, limiting their potential claims.
