The company plans to partner with EGA to build the first new American aluminum smelter in nearly 50 years at Inola, Oklahoma, a project designed to double domestic production and create over 1,000 permanent and 4,000 construction jobs. Following reinforcement of Section 232 measures, Century boosted primary aluminum output at its Mt. Holly, South Carolina smelter by nearly 10%, reflecting expanded capacity and stronger U.S.-based production. As the largest U.S. primary aluminum producer with roughly 60% domestic market share, Century intends to invest billions more in its Mt. Holly and Oklahoma projects to further reshoring efforts and support aerospace, automotive and defense industries. Century Aluminum stated that the U.S. Supreme Court upheld tariffs imposed under the International Emergency Economic Powers Act while leaving Section 232 steel and aluminum duties intact, preserving existing trade protections against foreign imports.
