The Proclamation further provides that foreign companies will qualify for a 10 percent duty rate if their capital equipment includes at least 85 percent US melted and poured or smelted and cast steel or aluminum by weight.

The changes set out in the Proclamation apply from June 8, 2026, until December 31, 2027.
