President Trump has announced via Truth Social that a 25% tariff will now take effect November 1st rather than October 1st and will apply to both medium (10,001 to 26,000 lbs. gvw) and heavy-duty trucks (over 26,000 lbs. gvw) coming into the United States from other countries. It is not known yet if the tariff, like the one on automobiles, will also include truck parts, or if there will be any exemptions or exclusions. No official legal text has been released, so specifics are not available.

These tariffs are imposed under Section 232 of the Trade Expansion Act of 1962, the same legal authority used for the steel, aluminum, copper, and automobile and auto part tariffs. They are separate from the country-specific tariffs imposed under the President’s emergency powers that are currently being challenged in court.
