Total Effective Rate

Importers sourcing pharmaceutical products from Japan face specific tariff considerations, with approximately $218B in total bilateral trade.

The current tariff framework for pharmaceutical products 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.

Pharmaceutical Products (HTS Chapter 30) generally enter duty-free at the MFN level, with the Section 122 tariff as the primary duty. No additional Section 232 or Section 301 surcharges apply to most products in this category from Japan.
