The United States has imposed new tariffs of up to 12.5% on imports from South Korea and 59 other countries, citing persistent failures to combat forced labor in their supply chains.

The duties, which range from 10% to 12.5%, mark a significant escalation in Washington’s trade policy, targeting major trading partners including Japan alongside emerging markets.

US Trade Representative Jamieson Greer announced the measures, framing them as necessary steps to enforce labor standards and protect American workers from unfair competition.

The broad scope of the tariffs introduces fresh uncertainty for global supply chains, particularly in the automotive, electronics, and textile sectors where South Korea and Japan are dominant exporters.

Markets are likely to reassess exposure to these regions, with investors scrutinizing companies that rely heavily on imports from the affected nations.

The move also risks triggering retaliatory measures, potentially disrupting trade flows and increasing costs for multinational corporations.
