WASHINGTON—The Trump administration announced on March 11 the launch of new trade investigations to address unfair trade practices as it seeks to replace reciprocal tariffs recently struck down by the Supreme Court.
There will be two separate investigations under Section 301 of the Trade Act of 1974, which may result in tariff increases on certain countries, U.S. Trade Representative Jamieson Greer said in a call with reporters.
