Amending Procedures for Submissions by Importers of Automobiles Qualifying for Preferential Tariff Treatment Under the USMCA To Determine U.S. Content

In Proclamation 10908 of March 26, 2025, "Adjusting Imports of Automobiles and Automobile Parts Into the United States," the President imposed additional tariffs on imports of specified automobiles and automobile parts to eliminate the threat to national security posed by such imports. That Proclamation also provided that for automobiles that qualify for preferential tariff treatment under the United States-Mexico-Canada Agreement (USMCA), importers of such automobiles may submit documentation to the Secretary of Commerce (Secretary) identifying the amount of U.S. content in each model imported into the United States. In a Federal Register Notice published on May 20, 2025, "Procedures for Submission by Importers of Automobiles Qualifying for Preferential Tariff Treatment Under the USMCA to Determine U.S. Content," the Department of Commerce (Department) established procedures for submission and review of such documentation. This Notice amends those procedures to conform those procedures with the submission timelines for medium- and heavy-duty vehicles, consistent with Proclamation 10984 of October 17, 2025, "Adjusting Imports of Medium- and Heavy-Duty Vehicles, Medium- and Heavy-Duty Vehicle Parts, and Buses Into the United States."
