According to reports, Century Aluminum in South Carolina is hiring workers again even though it is operating at half of its capacity.
The plant has resumed hiring after President Trump imposed tariffs on foreign aluminium imports.
Century president and CEO Mike Bless told analysts during a recent conference call that the tariffs are having their intended effect, allowing American industry to reinvest for long-term competitiveness.
Century this month reported a 21 percent increase in sales for the second quarter. Full-year production is expected to be up more than 60 percent over last year.
Bless said the company plans to continue operating at its current production level through the end of next year.
