President Trump has proposed tariffs of at least 10 percent on 60 American trading partners, his most aggressive effort yet to enact new import duties after the Supreme Court struck down the administration’s sweeping tariffs.
Jamieson Greer, the U.S. trade representative, said on Tuesday night that investigations found that the 59 countries, along with the 27-nation European Union, had failed to enact or effectively enforce laws prohibiting imports made with forced labor.
The administration, invoking a legal provision known as Section 301, proposed a 12.5 percent duty on imports from countries including China, Brazil, South Korea, Switzerland and Britain. Goods from the European Union, Canada and Mexico would face 10 percent import taxes.
Mr. Trump has signaled he intends to use Section 301 to rebuild his tariff agenda after the Supreme Court ruled that he exceeded his authority by using the International Emergency Economic Powers Act, or IEEPA, to impose duties without congressional approval.
After the court struck down those tariffs, Mr. Trump sought to revive them partly with a global 10 percent duty under Section 122 of the Trade Act of 1974, a never-before-used provision. A trade court ruled in May that the move violated the law. The tariffs were initially scheduled to expire at the end of July.
