Tariff Updates Under U.S.–Korea Agreement

The Office of the U.S. Trade Representative (USTR) announced today, December 3, 2025, that tariff modifications under the recent U.S.–South Korea agreement and outlined in a Nov. 13 fact sheet apply retroactively:

• Automobiles & Auto Parts: Effective for entries on or after Nov. 1, 2025
• Other Products (timber, lumber, aircraft parts, etc.): Effective for entries on or after Nov. 14, 2025

These changes are detailed in the Federal Register notice and modify the HTSUS as outlined in the agreement’s annex.
