The U.S. Customs and Border Protection (CBP) agency announced it will cease the collection of tariffs imposed under the International Emergency Economic Powers Act (IEEPA) starting at 12:01 a.m. EST on February 24, 2026. This decision follows the U.S. Supreme Court’s ruling stating that these tariffs are illegal. The CBP communicated this development to shippers via its Cargo Systems Messaging Service (CSMS), indicating that all tariff codes related to former President Donald Trump’s IEEPA orders would be deactivated on the specified date.
This suspension of IEEPA tariff collections aligns with Trump’s introduction of a new 15% global tariff under a different legal framework, designed to replace the tariffs that were invalidated by the Supreme Court on February 20. Notably, the CBP did not provide reasons for the continued collection of tariffs prior to the Supreme Court’s decision, nor did it mention any potential refunds for importers who were subject to these tariffs.
The Supreme Court ruling has significant implications, potentially impacting over $175 billion in U.S. Treasury revenue generated from the IEEPA tariffs, which, according to estimates from the Penn-Wharton Budget Model, were yielding more than $500 million in gross revenue daily. Additionally, CBP clarified that the halt on IEEPA tariff collections does not affect other tariffs imposed under different statutes, including those related to national security and unfair trade practices. The agency committed to providing further guidance to the trade community through subsequent CSMS messages.
