 What Happened

On March 6, 2026, the U.S. Court of International Trade (CIT) issued an order in Atmus Filtration, Inc. v. United States that temporarily pauses U.S. Customs and Border Protection (CBP) from taking immediate action to remove or refund tariffs imposed under the International Emergency Economic Powers Act (IEEPA).

On February 20, the U.S. Supreme Court issued a ruling invalidating the International Emergency Economic Powers Act (IEEPA) as a mechanism to levy tariffs. While the tariffs are invalidated and stopped being collected on February 24^th at 12:01 AM, the ruling did not provide operational clarity for importers seeking refunds of IEEPA duties already paid.

U.S. Customs and Border Protection (CBP) has issued CSMS #67844987, providing operational guidance implementing the Administration’s temporary global tariff action under Section 122 of the Trade Act of 1974, following the President’s February 20, 2026 Proclamation.

Today, the U.S. Supreme Court ruled that the government cannot use the International Emergency Economic Powers Act (IEEPA) to impose tariffs. This is a significant legal change, but there is no immediate operational impact for importers. Duties under IEEPA must still be paid, and refund questions remain unresolved. IEEPA tariffs will be replaced with a 10% global tariff under Section 122 of the Tariff Act of 1974.

U.S. Customs and Border Protection (CBP) has issued new guidance (CSMS #66319804) that significantly impacts how importers and brokers must report replacement duties under Chapter 99 of the Harmonized Tariff Schedule of the United States (HTSUS). This update specifically affects certain imports from the European Union, Japan, and the United Kingdom—and has direct implications for drawback filers seeking to preserve eligibility.
