We have passed the 100-day mark in the second Trump Administration and tariffs remain the talk of the town, with President Trump taking more trade-related actions in this time than any other president in modern history. As the Administration grapples with the domestic and international responses to the tariffs that have been implemented, it continues to undertake new measures directed at imports of targeted products.
On April 23, the Commerce Department announced that the Secretary of Commerce initiated two more Section 232 Investigations into the national security impact of imports – one on imports of processed critical minerals as well as their derivative products; and another on imports of medium-duty trucks, heavy-duty trucks, and medium- and heavy-duty truck parts. The Commerce Department is accepting comments on these investigations from interested parties until May 16, 2025.
With tariffs about to take effect on automotive parts at the end of this week, the Trump Administration has given some relief for U.S. automakers that assemble vehicles in the U.S. that include imported parts. In a proclamation made on April 29, President Trump announced an offset to a portion of the tariffs on imported automobile parts used by automakers in U.S.-assembled vehicles, which will be calculated based on automakers' U.S. sales and the vehicles' MSRP.
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 April 30, 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.
