The US customs agency is building a tariff refund system under judicial oversight after the Supreme Court struck down IEEPA tariff authority. Components range from 45 to 80 percent complete; trade specialists warn of a filing rush once the platform goes live.
Hundreds of thousands of US companies that paid duties under emergency trade authority are awaiting refunds, while the government agency responsible for processing them builds the required system under court supervision and time pressure.
U.S. Customs and Border Protection (CBP) is building a four-part processing system called the Consolidated Administration and Processing of Entries (CAPE) within its existing trade data platform. The agency’s progress was detailed in a declaration filed on March 19 with the US Court of International Trade in Atmus Filtration, Inc. v. United States (downloadable at the bottom of this page).
What is the current status of the refund system?
As of March 19, the four CAPE components were at different stages of development. The Review and Liquidation/Reliquidation component was the most advanced, at 80 percent complete. The Claim Portal stood at 73 percent, the Refund component at 63 percent, and Mass Processing – which handles bulk automated updates to entry summaries – at 45 percent complete.
However, all four components must pass multiple rounds of testing before deployment to the live ACE environment. Completion of certain components also depends on progress in others. April 20 is a development target rather than a hard statutory deadline.
A filing rush is coming: what can companies expect?
The scale of the task is substantial. Approximately 330,000 importers are affected, with over 53 million entries and an estimated $166 billion in potential refunds at stake, according to data cited in the proceedings. Some analysts compare this programme to COVID-era government relief, when a simultaneous surge of claims slowed processing and delayed funds even when systems worked as designed.
Uncertainties on all sides
The refund build is not the only operational strain on U.S. Customs and Border Protection. The same teams overseeing CAPE are also preparing for a complex trade environment following the invalidation of IEEPA duties and the administration’s subsequent shift to other tariff authorities. In short, they are racing to prepare a system that may change again, could be invalidated again, and will need updates as soon as it launches.
