On October 17, local time, U.S. President Trump signed an executive order imposing a new 25 percent tariff on imported medium and heavy-duty trucks and parts. The measure is set to take effect starting November 1.

The order targets trucks and related components entering the United States, adding a clear cost layer for importers in that segment. The November start date gives the trade measure a fixed timeline rather than an open-ended warning.

Trump also said a 10 percent tariff would be imposed on imported passenger cars. Together, the truck and passenger-car measures point to a broader tightening of U.S. import tariffs on vehicles and parts under the new executive action.
