President Trump’s overhaul of Section 232 tariffs on steel, aluminum, and copper takes effect today, April 6, 2026. The policy change follows an initial announcement made on April 2.
New rules shift duty calculations from metal-content value to the full customs value of imported goods. This shift increases costs for metal-intensive sectors including aerospace and defense.
Derivative products substantially made of targeted metals now face a 25% tariff on their total value. Goods made almost entirely of steel, aluminum, or copper are subject to a 50% tariff.
The policy aims to prevent foreign producers from circumventing existing duties. Higher import prices for critical components will affect the entire supply chain for manufacturers tracked by XAR.
