Korean exports could face an additional U.S. tariff of more than 12 percent after the U.S. Trade Representative (USTR) moved Tuesday to impose levies on goods from 60 economies it says are failing to keep products made with forced labor out of American markets.

The USTR

in

an investigative report determined that 54 economies — including Korea, China, Japan, Britain, Australia and Taiwan — "failed to impose and effectively enforce a prohibition on the importation of goods produced with forced labor," citing that they lack sufficient laws, institutions and enforcement mechanisms to prevent the import of goods made with forced labor. It proposed imposing an additional 12.5 percent tariff on those economies.
