The U.S. Court of International Trade upheld President Trump's decision to end the de minimis exemption for imports worth $800 or less, ruling that the International Emergency Economic Powers Act lets the president revoke that customs privilege even though the same law could not support his sweeping "Liberation Day" tariffs. The three-judge panel said rescinding the exemption is legally distinct from imposing tariffs because it withdraws a privilege rather than creating an open-ended new duty power. Detroit Axle, a family-run auto-parts distributor, challenged the move after the Supreme Court's February ruling against Trump's broader tariff program. Trump called the decision a "BIG WIN." The practical effect may be limited because Republicans already codified the policy in the One Big Beautiful Bill Act, which will permanently end the exemption next July, while a separate case over 10% to 12.5% surcharges on goods from 60 trading partners is set for oral arguments on Sept. 30.
