The World Trade Organization frictions have flared after the U.S. reworked Section 232 metal tariffs on April 2, 2026, prompting fresh international scrutiny. (whitehouse.gov. (whitehouse.gov)) The April 2 proclamation shifts Section 232 duties to the full customs value of covered steel, aluminum and copper articles and their derivatives and took effect for goods entered on or after April 6, 2026. (perkinscoie.com. (perkinscoie.com)) The new framework creates multiple rate tiers and redefines which derivative products are covered, changes that trade lawyers say widen the scope of duties beyond prior metal-content calculations. (whitecase.com. (whitecase.com)) Canada formally requested World Trade Organization consultations after U.S. duties were reimposed, circulating its consultation request to WTO members on March 13, 2025. (thehindu.com. (thehindu.com)) A three-judge panel of the U.S. Court of International Trade heard over three hours of oral argument on April 10, 2026 in consolidated challenges including State of Oregon v. Trump and Burlap & Barrel, Inc. v. Trump. (politico.com. (politico.com)) Under WTO procedure, complainants who cannot resolve issues in consultations may request a panel after the 60-day consultation period expires. (ustr.gov. (ustr.gov)) Trade firms and commentators including Sheppard Mullin and White & Case flagged specific legal questions about the full-value methodology, derivative coverage and how national-security justifications will be treated at the WTO. (sheppard.com. (sheppard.com)) The European Union has prepared countermeasures in past rounds and paused some retaliatory duties while negotiating; Geneva meetings have seen members raise “heightened trade turbulence” linked to U.S. tariff moves. (cnbc.com. (cnbc.com)) Section 232 duties trace back to the 2018 proclamations that set a 25% tariff on steel and a 10% tariff on aluminum, which were expanded and altered again in 2025 before the April 2026 overhaul. (congress.gov. (congress.gov)) If consultations do not resolve disputes, affected members can request a WTO panel after 60 days and the U.S. Court of International Trade — which heard oral argument on April 10, 2026 — will continue to consider domestic challenges to the administration’s tariff measures.
