New Tariffs on Japanese Automobiles and Auto Parts Take Effect Upon Federal Register Publication
Washington D.C. – New tariff rules governing imports from Japan, particularly impacting the automotive sector, will be implemented immediately upon publication of a notice in the Federal Register. The changes stem from a recent Executive Order enacting the United States-Japan Agreement, altering duties previously governed by Proclamation 10908 - the March 2025 Section 232 tariffs on automobiles and auto parts.
The agreement adjusts how tariffs are calculated for Japanese automobiles and auto parts. Previously subject to Section 232 tariffs,these goods will now follow a new structure: the duty rate will be determined by the product’s Column 1 Duty Rate in the Harmonized Tariff Schedule of the united States (HTSUS). If the Column 1 rate is less than 15%, a combined duty of that rate plus 15% will be applied. If the Column 1 rate is 15% or higher, no additional duty will be assessed. Unlike other provisions of the Executive Order, these changes are not retroactive.
For all other products from Japan entering or being withdrawn for consumption, the new tariff rules are effective as of today. Refunds for any overpayments made under the prior tariff structure will be processed through standard Customs and Border protection (CBP) procedures.
