U.S. Cuts Tariff on Japanese Auto Imports to 15% as Deal Takes Effect

The move implements a U.S.-Japan agreement via a Sept. 4 presidential order.

Overview

  • The new 15% rate took effect at 12:01 a.m. Eastern on Sept. 16, down from the 27.5% level in place since April.
  • The cut reflects reducing the 25% additional levy to 12.5%, combined with the long-standing 2.5% base duty.
  • The Commerce Department published the order on Sept. 15, detailing timing and related measures in the Federal Register.
  • A related reciprocal-tariff adjustment sets sub-15% lines to 15% and adds no further increases to items already at or above 15%, with refunds retroactive to Aug. 7.
  • Civil aircraft parts are excluded from the reciprocal-tariff scheme, and the administration frames the change as easing strain on Japan’s auto industry.
