U.S. tariff refund discussions intensify

The Supreme Court’s February 20 decision striking down tariffs imposed under the International Emergency Economic Powers Act has moved the tariff-refund debate from legal theory into administrative process. U.S. Customs and Border Protection has since published a dedicated IEEPA duty-refunds page, a fact sheet and filing guidance for a new ACE-based tool called CAPE. Congress’s research arm had already outlined the core question in January: how importers could recover duty deposits if the Court held the tariffs unlawful. ### What did the Supreme Court actually decide? The Supreme Court said on February 20 that IEEPA “does not give the President authority to impose tariffs,” according to a Congressional Research Service summary of the ruling and the Court’s opinion in *Learning Resources v. Trump*. The decision affirmed lower-court rulings against two groups of tariffs: duties tied to declared emergencies involving illicit drugs and broader “reciprocal” tariffs tied to the U.S. trade deficit. (supremecourt.gov) Chief Justice John Roberts wrote the opinion, and the case covered tariffs President Donald Trump had imposed in 2025 on imports from Canada, Mexico, China and many other trading partners, the opinion shows. CRS said the Court’s ruling did not itself spell out a refund mechanism for duties already collected. ### How much money is potentially at stake? Congressional Research Service said in a January 13 report that importers had paid about $129 billion in estimated duty deposits on entries covered by most IEEPA tariffs as of December 10, 2025. (supremecourt.gov) The same report said about 19.2 million of roughly 34 million affected entries remained unliquidated at that point. CRS said that matters because customs duties are first paid as estimated deposits and later finalized through “liquidation.” For unliquidated entries, the government may have to issue refunds at liquidation if the tariffs are unlawful; for entries already liquidated, the path can be narrower and more procedural. (supremecourt.gov) ### Where does the refund process stand now? CBP says it is developing and deploying a refund process through the Automated Commercial Environment under a tool called Consolidated Administration and Processing of Entries, or CAPE. (congress.gov) The agency says CAPE is designed to consolidate IEEPA duty refunds, including interest, rather than process refunds one entry at a time. CBP launched Phase 1 of CAPE on April 20, 2026, according to the agency’s IEEPA refunds page, fact sheet and trade notice. (congress.gov) Phase 1 is limited to certain unliquidated entries and certain entries within 80 days of liquidation, and filings must be submitted through the ACE Secure Data Portal by the importer of record or an authorized customs broker. CBP also says refunds are issued “pursuant to court order and in accordance with appropriate statutory authority,” language that underscores the agency is processing claims within legal limits rather than announcing a blanket Treasury reimbursement program. (cbp.gov) The agency has published technical guidance, declaration templates and error definitions for CAPE filers. ### What if an entry has already liquidated? (cbp.gov) CBP says that once liquidation has occurred, “the only option available for relief is to file a Protest.” The agency says importers, brokers or attorneys can contest CBP decisions within 180 days of liquidation under 19 U.S.C. 1514, including through the ACE protest module or paper filing at the port of entry. CRS said court-ordered reliquidation could also require refunds in some circumstances. (cbp.gov) That means the practical route may depend on the status of each entry, the timing of liquidation and whether an importer preserved its rights through protest or litigation. That is an inference from CBP’s protest rules and CRS’s refund analysis, not a new government announcement. ### Is there a formal Treasury-wide reimbursement plan? (cbp.gov) CBP’s public materials describe an operational refund channel through CBP and ACE, not a separate Treasury-wide cash reimbursement plan. Treasury was named as a party in the Supreme Court litigation, but the public guidance now posted for importers points to CBP’s IEEPA refund page, CAPE declarations, ACH enrollment and protest procedures. (congress.gov) CBP’s next public milestones are on its own website: updated IEEPA refund guidance, CAPE technical documents and Cargo Systems Messaging Service notices for trade users. As of May 17, 2026, those materials remain the clearest official source for who can file, which entries qualify in Phase 1 and how refund requests move through ACE. (cbp.gov) (supremecourt.gov)
