The U.S. Customs and Border Protection (CBP) said it will stop collecting tariffs imposed under the International Emergency Economic Powers Act (IEEPA) beginning at 12:01 a.m. EST (0501 GMT) on Tuesday, more than three days after the U.S. Supreme Court ruled the duties unlawful.
In a notice to shippers issued through its Cargo Systems Messaging Service (CSMS), CBP said it would deactivate all tariff codes linked to prior IEEPA-related orders signed by Donald Trump.
The suspension follows Friday’s Supreme Court decision striking down the tariffs imposed under IEEPA authority. CBP did not explain why collections continued at ports of entry in the days after the ruling, nor did it provide details on whether importers would receive refunds for duties already paid.
The halt coincides with the introduction of a new 15% global tariff announced by Trump under a separate legal authority, replacing the measures invalidated by the court.
CBP clarified that the suspension applies only to tariffs enacted under IEEPA and does not affect other duties imposed during Trump’s presidency. These include tariffs levied under the Section 232 national security statute and Section 301 of the Trade Act, which addresses unfair trade practices.
“CBP will provide additional guidance to the trade community through CSMS messages as appropriate,” the agency said.
