Despite Friday’s Supreme Court decision that ruled President Donald Trump’s “reciprocal” tariffs are illegal, U.S. importers are still paying duties on goods entering the country.

U.S. Customs and Border Protection (CBP) has yet to update its Cargo System Management Service to remove the duties imposed by Trump under the International Emergency Economic Powers Act (IEEPA). Under U.S. trade policy, Customs must post updates on tariff changes and other trade-related information on its Cargo Systems Messaging Service.

On Friday, Customs posted a bulletin on the decision saying, ”[T]he CBP is working with other government agencies to fully examine the implications of the SCOTUS decision. CBP will provide additional information and technical guidance for Automated Commercial Environment (ACE) filers as soon as it becomes available.”

CNBC was told by Customs that this is the latest update for importers for now.

The paperless Automated Commercial Environment is the Customs system used for processing imports and exports. An executive order signed by Trump in March charged the CBP with modernizing its manual payment system.
