On June 1, the U.S. imposed a 25 percent tariff on steel, and a 10 percent tariff on aluminum, imported from the European Union, Canada and Mexico.
Retaliation came quickly. The EU, for example, imposed tariffs on 180 products imported from the U.S., including steel, aluminum, agricultural goods, clothing, washing machines, cosmetics and, notably, motorcycles. Specifically, the EU increased the duty on motorcycles from 6 percent to 31 percent.
