WASHINGTON—The United States is requesting that a World Trade Organization dispute resolution panel get involved in a clash over international retaliation over U.S. tariffs on steel and aluminum, according to a U.S. official familiar with the matter.
The request, filed on Oct. 18, covers tariffs by China, the European Union, Canada and Mexico, which followed the United States imposing a 25 percent duty on steel imports and a 10 percent tariff on aluminum imports.
