Century Aluminum Doubles Down on U.S. Aluminum Expansion After Supreme Court IEEPA Ruling

Event summary

  • Century Aluminum increased U.S. primary aluminum production by 10% through Mt. Holly, S.C. smelter expansion.
  • Company plans to build first new U.S. aluminum smelter in nearly 50 years in Inola, Oklahoma, creating 1,000 permanent and 4,000 construction jobs.
  • Supreme Court ruling on IEEPA tariffs leaves Section 232 steel and aluminum tariffs intact.
  • Century Aluminum is the largest U.S. primary aluminum producer, smelting nearly 60% of the country's supply.

The big picture

Century Aluminum's expansion plans reflect a broader trend of reshoring critical mineral production to the U.S., driven by protective trade policies. The company's investments in new smelting capacity position it as a dominant player in the U.S. aluminum market, with potential implications for national defense and industrial supply chains. The Supreme Court's ruling on IEEPA tariffs reinforces the stability of Section 232 tariffs, which Century Aluminum has leveraged to justify its expansion.
