US Launches Section 301 Investigations Into Forced Labor Practices in 60 Countries

The United States has initiated a sweeping new round of Section 301 investigations targeting 60 countries—including South Korea, China, Japan, the European Union, India, Indonesia, Britain, Australia, Canada, and Taiwan—over alleged failures to address forced labor in supply chains. Announced by the US Trade Representative (USTR) in March 2026, these probes mark a significant escalation in US trade enforcement, with the Trump administration seeking to impose new tariffs and quotas after the Supreme Court invalidated previous trade taxes. The move has drawn immediate international attention, with several targeted economies pledging to defend their interests and ensure fair treatment.Reuters+2

⚖️ Section 301 Investigations: Forced Labor in Focus

The latest Section 301 investigations are centered on the enforcement of bans against importing goods produced with forced labor. The USTR aims to verify compliance and assess whether foreign governments are taking adequate action to eliminate forced labor from their export supply chains. This marks a shift from previous probes, which also focused on excess manufacturing capacity, and reflects the administration’s broader efforts to address labor rights in global trade. The investigations empower the US to impose high tariffs and import quotas as sanctions against countries found in violation.Reuters+2

🌐 International Responses and Diplomatic Engagement

Countries named in the investigations, including South Korea, have responded by emphasizing the need for close communication with the US to protect national interests and maintain trade fairness. Seoul’s trade minister noted that the probe may relate to earlier tariffs and trade measures, and pledged to seek equitable treatment. The European Union and China have also voiced concerns, warning against unilateral US actions and calling for dialogue to resolve disputes. The investigations have heightened diplomatic tensions and raised questions about the future of international trade agreements.Yonhap News Agency+2

🏛️ Enforcement Mechanisms and Policy Shifts

Following the February 20 Supreme Court ruling that canceled previous tariffs, the Trump administration is leveraging Section 301 as a new enforcement tool. The investigations are designed to support the imposition of new customs duties and other trade remedies targeting forced labor violations. This policy adjustment underscores a renewed US commitment to combating unfair labor practices and ensuring compliance with international labor standards in trade.Radio France Internationale+2

📅 Timeline and Next Steps

The Section 301 investigations were officially launched in March 2026. The process will involve evidence gathering, consultations with stakeholders, and formal reviews of each targeted country’s efforts to address forced labor. The USTR is expected to announce potential sanctions or settlements in the coming months, with outcomes likely to set new precedents for US trade policy and global economic relations.Reuters+2
