Trump Sets 25% Tariff on Imported Medium- and Heavy-Duty Trucks for Nov. 1

The move stems from a Section 232 national-security probe following industry pushback that delayed the start by a month.

Overview

  • Commerce Department investigators focused on trucks over 10,000 pounds and parts, citing dominance by a small group of foreign suppliers and alleged predatory practices.
  • Detroit automakers and suppliers lobbied against the original Oct. 1 timeline, warning of higher costs and supply-chain disruptions.
  • Mexico is the largest source of these vehicles; government filings note Mexican exports average about 50% U.S. content, and USMCA rules allow tariff-free entry at 64% regional value.
  • Potentially affected brands include Daimler Truck’s Freightliner and Volvo’s Mack, while Paccar largely builds for the U.S. market domestically; StellantisMexico-produced Ram and commercial vans face exposure.
  • The measure is part of a wider tariff agenda now facing court challenges, with the Supreme Court set to hear arguments on Nov. 5 regarding the administration’s trade authority.
