Total Effective Rate

Among US trading partners for arms and ammunition, Japan plays a notable role, with approximately $218B in total bilateral trade.

The current tariff framework for arms and ammunition from Japan reflects the post-SCOTUS landscape: a 10% Section 122 tariff replaced the previously higher IEEPA rates after the Court's February 2026 ruling.

The Section 122 tariff is subject to a 150-day statutory time limit and is set to expire approximately July 24, 2026, unless Congress acts to extend or replace it. Importers should monitor legislative developments closely as this deadline approaches.

Arms and Ammunition (HTS Chapter 93) carry an average MFN duty rate of 3% in addition to the Section 122 tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from Japan.

Key products in HTS Chapter 93 imported from Japan include Rifles, Shotguns, Pistols, Ammunition, Military weapons, and Hunting firearms.
