Mr. Trump’s tariffs had a de minimis impact on Chinese imports, which were already subject to 28 dumping duties. They principally reduced imports from Turkey, Russia and South Korea, which turned around and shipped more steel to other countries.
For example, U.S. imports from Turkey fell by 930,000 tons last year. But Turkey exported 330,000 more tons to Canada and 780,000 more tons to Italy. European steel makers have complained that a flood of imports is driving down prices. But lower prices have made European manufacturers more competitive. Some U.S.-based manufacturers like Harley-Davidson have also moved production to Europe to dodge retaliatory tariffs and take advantage of lower steel prices.
Negotiating leverage. The Trump Administration argued that it was using steel tariffs as a bargaining chip in negotiations with Mexico and Canada for a revised Nafta. “The president’s view was that it makes sense that if we get a successful agreement, to have them be excluded,” U.S. Trade Representative Robert Lighthizer said last March. “It’s an incentive to get a deal.”
