Trump's Section 232 Tariffs Hit Japan April 6: Steel and Aluminum Duties Surge to 50 Percent

Welcome to Japan Tariff News and Tracker, your essential update on how U.S. trade policies are impacting Japan. Today, we're diving into the latest Trump administration moves under Section 232 of the Trade Expansion Act, effective April 6, 2026, with key implications for Japanese exporters. On April 2, President Trump issued a proclamation revamping tariffs on steel, aluminum, copper, and their derivatives, shifting from content-based duties to full customs value assessments. Annex I-A products like core steel and aluminum articles now face a base 50% tariff on their entire value, while Annex I-B derivatives drop to 25%, according to the Brownstein Client Alert from Brownstein Hyatt Farber Schreck. This replaces the prior 50% on metal content only, aiming to bolster U.S. industries, as stated in the White House fact sheet cited by multiple outlets including JD Supra's trade alert. Japan, a major supplier of these metals and auto parts, benefits from targeted exemptions. Products with 15% or less steel, aluminum, or copper by weight escape Section 232 duties entirely, per Annex IV details in the proclamation reported by Thompson Hine. Drawback claims for manufacturing are available for Japanese goods containing U.S.-sourced metals smelted in Japan, a trade agreement partner, as outlined in the Torres Trade Law analysis. Lower 10% rates apply to U.S.-origin metal derivatives, potentially incentivizing Japan-U.S. supply chain shifts. No Japan-specific rate hikes appear in this round, unlike threats against Iran at 50% per Politico, but Japanese firms must now provide detailed origin tracing for smelt/cast/melt/pour certifications to claim relief, warns Ropes & Gray. Amid broader actions like 100% tariffs on patented pharmaceuticals starting July 31 for select firms, per the proclamation, Japan's precision manufacturers watch closely for expansions. These changes signal Trump's ongoing push to reshape global trade, pressuring Japan to deepen onshoring deals. Stay tuned as negotiations evolve.
