Nucor applauds President Trump's announcement of 25% steel tariff Nucor Corporation is pleased that President Trump moved forward to implement the tariffs on steel imports he announced last week. "We thank the President for taking decisive and meaningful action to address the massive flood of dumped and illegally subsidized steel imports into the United States," said Nucor CEO John Ferriola. "For too many years, Nucor and other American steelmakers have dealt with this chronic problem, which is fueled by foreign governments' subsidies and preferential treatment for their steel industries in violation of international trade agreements and free market principles.
