The Trump Administration has taken significant actions to impose or substantially revise tariffs on key US trading partners. Negotiations with certain countries remain ongoing and tariffs are subject to change. Our Tariff Tracker monitors and summarizes these changes.

The US has primarily relied upon the International Emergency Economic Powers Act (IEEPA) as the statutory basis on which to ground the imposition of tariffs. President Trump is the first US president to do so and the IEEPA-based tariffs are currently subject to multiple court challenges. Although the levies have been found to be unlawful by two lower courts, those decisions are currently on appeal.

In addition to the IEEPA-based tariffs, the US has imposed tariffs pursuant to Section 232 of the of the Trade Expansion Act of 1962, which authorizes imposing tariffs on goods that impact US national security. Currently, Section 232 tariffs are in place for copper, steel, aluminum, and automobiles and automotive parts. There are also currently nine separate trade investigations into other products such as semiconductors, pharmaceuticals, critical minerals and derivative products, commercial aircraft and jet engines, polysilicon and its derivatives, and unmanned aircraft systems, among others. Each of these investigations could ultimately lead to further sectoral tariffs.

We have prepared the below tracker to provide a snapshot of these tariff measures.
