Almost as soon as they were vacated by the Court of International Trade (“CIT”), President Trump's reciprocal tariffs and trafficking-related tariffs on China, Canada and Mexico, all of which were issued under the International Emergency Economic Powers Act (“IEEPA”), were reinstated, at least temporarily by the U.S. Court of Appeals for the Federal Circuit. On May 29, the U.S. Court of Appeals for the Federal Circuit issued an immediate administrative stay of the CIT’s order vacating the tariffs. Pending the resolution of the government’s appeal to the Federal Circuit, the reciprocal tariffs and trafficking-related tariffs will remain in effect and duties will be collected.
Adding to the tariffs that were already implemented, on June 3, President Trump issued a proclamation increasing the tariff rate for imports of steel articles and derivative steel articles, and aluminum articles and derivative aluminum articles, from 25 percent ad valorem to 50 percent ad valorem, effective as of June 4, 2025.
Keeping track of all of the tariffs that have been promulgated or proposed during the Trump Administration continues to be a head-spinning task. To help follow the proliferation of tariffs in the Trump Administration, I have put together the following list of each of the tariff measures that have been implemented, pending, or proposed since January 20, 2025.
Here is the developing landscape of U.S. tariffs as of June 4, 2025:
This list will be updated weekly as new tariffs are implemented and new targets for tariffs are identified by President Trump and the administration.
