15% Tariff Floor for Korean Cars
If you import passenger vehicles or light trucks that are products of South Korea, the rule makes the total U.S. duty equal to 15% when the applicable Column 1 duty rate is less than 15%.

Civil Aircraft and Parts Exempted From Added Tariffs
Civil aircraft (all aircraft other than military and unmanned), their engines, parts, components, subassemblies, and ground flight simulators that are products of South Korea are not subject to the additional duties imposed under Executive Order 14257 and the listed proclamations. That exclusion is reflected in new heading 9903.02.81 and applies to goods entered for consumption on or after 12:01 a.m. eastern time on November 14, 2025.
No Extra Duty When Duty ≥ 15%
If you import passenger vehicles, light trucks, or parts of South Korea that already have a Column 1 duty rate of at least 15%, the additional ad valorem duty described in the U.S.-ROK Deal will be zero. This treatment for automobiles and automobile parts is effective for goods entered for consumption on or after 12:01 a.m. eastern time on November 1, 2025.
Auto Entries Exempt From Other Added Duties
Entries of the passenger vehicles, light trucks, and automotive parts described in the notice will not be subject to certain additional duties on copper, aluminum, iron or steel, derivative metal products, and several wood-product additional-duty headings.

15% Duty for Korean Timber and Wood Products
For timber, lumber, and derivative wood products that are products of South Korea, the sum of the Column 1 duty rate and any additional ad valorem duty under Proclamation 10976 will be 15% when the Column 1 rate is less than 15%; if the Column 1 rate is at least 15% no additional duty applies.
