A federal refund system for businesses that paid contested import tariffs is set to go live Monday, marking the first operational step in unwinding a major legal setback for former U.S. President Donald Trump’s trade policy. The move follows a ruling by the U.S. Supreme Court, which determined that the tariffs had been imposed without proper constitutional authority.
Administered by U.S. Customs and Border Protection, the system will allow importers and their customs brokers to begin filing claims through an online portal starting at 8 a.m. The process is expected to be complex and phased, potentially extending beyond businesses to include consumers who indirectly bore the cost of the tariffs through higher prices.
To initiate claims, companies must submit detailed declarations identifying the goods on which they paid billions of dollars in import duties—taxes that were later invalidated by the courts. Once a claim is approved, CBP estimates that refunds will be issued within 60 to 90 days. However, the agency has indicated that reimbursements will be processed in stages, prioritizing more recent tariff payments. As a result, companies—and by extension, consumers—may experience delays due to technical and procedural hurdles.
The legal foundation for the refunds stems from a 6–3 Supreme Court decision issued on February 20, which concluded that Trump overstepped congressional authority by invoking emergency powers under a 1977 statute to justify sweeping tariff increases. While the high court did not directly address restitution, a subsequent ruling by the U.S. Court of International Trade affirmed that companies subjected to tariffs under the International Emergency Economic Powers Act are entitled to recover those funds.
According to court filings, more than 330,000 importers collectively paid approximately $166 billion in tariffs across 53 million shipments. The initial phase of the refund program will apply only to a subset of these transactions—specifically, those involving estimated duties that have not yet been finalized or that fall within 80 days of final accounting.
Participation in the refund system requires registration with CBP’s electronic payment platform. As of April 14, nearly 56,500 importers had completed registration, representing an estimated $127 billion in eligible refunds, including accrued interest.
Legal and financial experts are urging companies to proceed with caution. Meghann Supino, a partner at Ice Miller, emphasized the importance of precision in filing. Even minor discrepancies in documentation—such as incorrect form numbers or incomplete entries—could result in partial or full rejection of a claim. She also noted that the portal’s launch could encounter early technical disruptions, advising applicants to remain patient as the system stabilizes.
Nghi Huynh, partner-in-charge of transfer pricing at consulting firm Armanino, highlighted the operational challenges businesses may face. Many importers handle mixed shipments, meaning not all goods will qualify for immediate refunds. She stressed the need for rigorous tracking systems to ensure accuracy across potentially thousands of line items per submission.
For small businesses, the rollout represents a long-awaited opportunity to recover losses. Brad Jackson, co-founder of After Action Cigars in Minnesota, said his company paid approximately $34,000 in tariffs last year on imports from Nicaragua and the Dominican Republic—costs it largely absorbed rather than passing on to customers. While Jackson has prepared extensively for the application process, he expressed concern over the timeline.
“A refund process that takes several months doesn’t solve the immediate cash flow challenges it’s meant to address,” he said.
Although the refunds will be issued directly to businesses, there is no requirement for companies to pass the money back to consumers. Nonetheless, a wave of class-action lawsuits is already moving through the courts, targeting major retailers and manufacturers in an effort to compel reimbursement.
Consumers may have a clearer path to restitution in cases where tariffs were collected directly at the point of delivery. Companies such as FedEx and UPS have indicated they intend to return refunded duties to customers once they receive payments from CBP. FedEx confirmed it will begin filing claims as the system opens, reiterating its commitment to supporting customers through ongoing regulatory changes.
As the refund portal launches, businesses across sectors are preparing for a process that promises financial relief—but one that will require precision, patience, and time to fully unfold.
