Copper and nickel ores and concentrates have not historically been primary targets of US antidumping or countervailing duty orders, though downstream refined metals and products have faced various measures. However, trade professionals should monitor Section 232 national security reviews and any critical minerals executive actions, as the policy landscape for strategic metals is evolving rapidly.

US critical minerals policy — including provisions in the Inflation Reduction Act and Defense Production Act — creates incentives to source nickel and copper from free-trade-agreement partners or allied nations for certain downstream applications (notably EV battery supply chains). Importers and processors should assess whether their sourcing geography qualifies for any domestic content or sourcing incentives, and consult legal counsel on evolving eligibility rules.
