U.S. Reduces Korean Auto Tariff to 15% Retroactive Nov. 1, Extends Cuts to Aircraft and Lumber
Updated (2 articles)
Tariff reduction applied to autos, parts, aircraft and lumber The United States lowered the duty on Korean automobiles and auto parts from 25 % to 15 %, making the change retroactive to Nov. 1, 2025. Tariffs on Korean aircraft components and on timber, lumber and derivatives were also reduced to 15 % starting 12:01 a.m. on Nov. 14, 2025. Both changes were announced in a Federal Register notice on Dec. 3, 2025 [1][2].
South Korean investment pledge tied to tariff cuts Seoul committed to invest US$350 billion in the United States as part of the Korea‑U.S. Strategic Trade and Investment Deal, a promise formalized in a memorandum of understanding signed on Oct. 30, 2025. The investment commitment was a condition for the reciprocal tariff reductions and is expected to span multiple sectors, including manufacturing and technology. This pledge was highlighted by Industry Minister Kim Jung‑kwan during the announcement [1][2].
Reciprocal tariff rate set at 15 % with specific exemptions The United States instituted a uniform 15 % reciprocal tariff on Korean goods, replacing the previous 25 % rate across the board. Korean civil aircraft are exempt from additional sector‑specific tariffs on steel, aluminum and copper, while unmanned aircraft remain excluded from the tariff reduction. These provisions align with WTO agreements on civil aircraft trade [1][2].
Deal finalized at October summit; implementation timeline clarified The trade and investment agreement was concluded during an October summit between President Lee Jae‑Myung and President Donald Trump in South Korea. The Federal Register notice posted on Dec. 3 precedes the official publication scheduled for Dec. 4, giving U.S. importers time to adjust to the new rates. The announcement emphasized the durability of the U.S.–Korea alliance [1][2].
