President Donald J. Trump Updates Tariffs on Steel, Aluminum, and Copper Imports – 2 June 2026
Summary:
The U.S. White House has officially announced updated Section 232 tariff frameworks to bolster domestic manufacturing and counter security risks. Notably, the proclamation introduces a mechanism allowing foreign companies to qualify for a lower 10% duty rate on their goods, provided their capital equipment contains at least 85% U.S. melted/poured or smelted/cast aluminium and steel by weight. This policy push, alongside the newly announced Century Aluminum and Emirates Global Aluminum joint venture smelter in Oklahoma, signals a tightening of domestic supply loops that will alter global extrusion and billet trade flows.
