New Section 232 Proclamations Impact Aluminum Derivative Products – 15 April 2026

Summary: Effective this week, new U.S. trade proclamations have adjusted tariff treatments for aluminum, steel, and copper. The Aluminum Extruders Council (AEC) has issued a member alert regarding these changes, which specifically target derivative articles. Manufacturers should review their import/export portfolios as the 50% ad valorem duty rate now applies to specific categories to protect domestic capacity.
