1834 ET [Dow Jones]--Alcoa says its strongest argument against the current 50% tariff on imported aluminum is the long odds of quickly adding more U.S. aluminum production. Alcoa has been supplying the U.S. market from smelters in Canada where electricity costs are more favorable for operating a smelter. The U.S. imports about four million metric tons of aluminum annually, the company says. "It would probably cost $30 billion to put four million metric tons here," CEO William Oplinger says. "It would probably take us at least five years. We're educating the government on those facts." (robert.tita@wsj.com)
