Japan Secures Aerospace Tariff Exemptions as US Refunds 166 Billion in Unconstitutional Trump Era Duties

Welcome to Japan Tariff News and Tracker, where we break down the latest U.S. trade moves impacting Japan. Today, as the U.S. Customs and Border Protection portal launches at 8 p.m. ET, American importers can finally claim refunds on $166 billion in Trump-era tariffs ruled unconstitutional by the Supreme Court two months ago, according to CNN and Fox Business reports. Over 330,000 businesses paid duties on 53 million shipments under the invalid International Emergency Economic Powers Act, with refunds plus interest flowing through the new Consolidated Administration and Processing of Entries system. While refunds unwind old policies, Trump 2.0 tariffs press forward, and Japan scores key exemptions. The Trade Compliance Resource Hub's tracker highlights a Japan aerospace exemption effective September 16, 2025, shielding critical components from Section 232 duties on aluminum and derivatives. Under updated rules from April 6, 2026, per the Trade Expansion Act proclamation, Japan-origin aluminum products with at least 95% content smelted or cast in compliant nations face tiered rates: 25% for most Annex I-A articles, dropping to 10% for U.S.-sourced derivatives, as detailed in HTSUS Chapter 99 notes. No broad Japan-specific hikes appear in current trackers—unlike threatened 500% duties on Russia-linked imports or 50% on Iran suppliers—but Section 301 investments and Section 122's 10% baseline (implemented February 24, 2026) apply globally unless exempted. Trade Compliance Resource Hub notes Trump's fondness for tariffs as "the most beautiful word," with ongoing aluminum tweaks emphasizing origin and security. For Japanese exporters in autos, aerospace, and metals, these carve-outs offer breathing room amid North American shifts hitting USMCA goods, as analyzed by The People's Economist. Yet, volatility persists: Yale's Budget Lab links past tariffs to 2% consumer price hikes through early 2026, with full passthrough on durables. Stay ahead—Japanese firms should verify ACE portal eligibility and monitor Commerce Department updates for stacking rules on reciprocal tariffs.
