U.S. to stop collecting tariffs deemed illegal by Supreme Court on February 23

U.S. halts illegal tariff collections as Supreme Court ruling takes effect, impacting $175 billion in potential refunds.

The U.S. Customs and Border Protection (CBP) agency said it will halt collections of tariffs imposed under the International Emergency Economic Powers Act at 12:01 a.m. EST (0501 GMT) on Tuesday (February 24, 2026), more than three days after the U.S. Supreme Court declared the duties illegal.

The agency said in a message to shippers on ‌its Cargo Systems Messaging Service (CSMS) that it ‌will ⁠de-activate all tariff codes associated with President ⁠Donald Trump’s prior IEEPA-related orders as of Tuesday (February 24).

The IEEPA tariff collection halt coincides with Mr. Trump’s imposition of a new 15% global tariff under a different legal authority to replace the tariffs struck down by the Supreme Court on Friday (February 20).

CBP gave no reason why ‌it was continuing to collect the tariffs at ports of entry days after the Supreme Court’s ruling, and its ⁠message offered no information about possible refunds for importers.

The message noted that the collection halt ‌does not affect any other tariffs imposed by Mr. Trump, including those under the Section 232 national security statute and the Section 301 unfair trade practices statute.
