Mar 27, 2026 - President Donald Trump announced the imposition of a 25 percent tariff on imported automobiles and certain automobile parts, citing national security concerns under Section 232 of the Trade Expansion Act of 1962.
The White House issued a proclamation on Wednesday that applies the tariff to passenger vehicles, including sedans, SUVs, crossovers, minivans, cargo vans and light trucks, as well as key components such as engines, transmissions, powertrain parts and electrical systems. The measure takes effect for vehicles on April 3 and for parts no later than May 3.
The administration stated that the tariffs aim to address threats to domestic automobile production and reduce reliance on foreign imports and parts. Importers of vehicles under the United States-Mexico-Canada Agreement will have the opportunity to certify U.S. content, with the tariff applying only to the value of non-U.S. content. USMCA-compliant automobile parts are expected to remain tariff-free pending establishment of a process to apply duties to non-U.S. content.
The announcement follows earlier tariff actions on steel, aluminum and other sectors. Modified rates have been negotiated with some trading partners, resulting in lower duties of 15 percent on vehicles from the European Union, Japan and South Korea under separate agreements. Most vehicles and parts from Canada and Mexico that comply with USMCA rules have faced adjustments based on non-U.S. content rather than full application of the 25 percent rate.
The U.S. imported millions of passenger vehicles and billions of dollars worth of auto parts annually in recent years. Major sources have included Mexico, Canada, Japan, South Korea, Germany and other European countries. The new tariffs add to existing duties, including the longstanding 2.5 percent tariff on passenger vehicles and 25 percent on light trucks.
Industry groups have reported that previous tariff measures on autos and parts implemented in 2025 increased costs for manufacturers. Some automakers have absorbed portions of the duties or adjusted supply chains, while others have passed costs to consumers through higher vehicle prices. Repair and maintenance expenses have also risen due to elevated parts costs.
The move coincides with broader trade policy actions by the Trump administration, including reciprocal tariffs on various imports. It occurs as the United States maintains military deployments in the Middle East amid tensions with Iran, though officials have not linked the auto tariffs directly to those events.
As of Thursday, the Commerce Department and U.S. Customs and Border Protection were finalizing implementation details, including certification processes and potential offsets for U.S.-assembled vehicles that incorporate imported parts. No immediate changes to the tariff schedule were announced, and foreign governments had not yet issued formal responses to the latest announcement.
