Timeline: Effective for goods entered on or after 12:01 a.m. Eastern Time on August 19, 2026

Summary: This proclamation imposes a 50% additional ad valorem duty on certain Canadian motor vehicle products to offset Canada’s discriminatory tariffs favoring vehicles from other countries. The tariffs aim to address a 22% decline in U.S. vehicle exports to Canada and are authorized under Section 338 of the Tariff Act of 1930. U.S. Customs and Border Protection, with consultation from Treasury, Commerce, and USTR, will enforce these duties. The measure is expected to impact international trade relations, automotive research, and economic conditions affecting institutions like Vanderbilt University.

Key Actions: Evaluate trade and research implications for automotive partnerships; analyze economic impacts on manufacturing and trade policies; explore opportunities in green transportation technologies; monitor U.S.-Canada trade relations; and engage policymakers to support U.S. automotive producers.
