USTR Launches Section 301 Investigations into Excess Capacity and Forced Labor
Summary
The U.S. Trade Representative (USTR) has initiated two Section 301 investigations. The first examines excess manufacturing capacity in 16 economies, and the second investigates forced labor practices in 60 countries. These actions could lead to new tariffs impacting U.S. commerce.
What changed
The U.S. Trade Representative (USTR) has launched two significant Section 301 investigations. The first, announced on March 11, 2026, targets 16 economies for structural excess capacity and production in their manufacturing sectors, citing concerns that overproduction is harming U.S. domestic production and investment. The second investigation, initiated on March 12, 2026, involves 60 countries and addresses alleged failures to ban the importation of goods produced with forced labor, which USTR states creates an unfair cost advantage for foreign producers.
These investigations, authorized under Section 301(b) of the Trade Act of 1974, could result in the imposition of new tariffs on goods from the investigated countries. Companies involved in international trade, particularly those manufacturing or importing goods from the listed economies, should monitor these proceedings closely. The USTR has identified specific sectors and inputs affected by excess capacity and forced labor, including aluminum, automobiles, textiles, and critical minerals. While no specific compliance deadlines or penalties are detailed in this announcement, the potential for significant trade actions necessitates a review of supply chain vulnerabilities and import practices.
What to do next
- Review list of 16 economies for excess capacity investigation and assess potential impact on supply chains.
- Review list of 60 countries for forced labor investigation and assess potential impact on imported goods.
- Monitor USTR announcements regarding findings and potential tariff actions.
Penalties
Potential imposition of tariffs.

Section 301(b) of the Trade Act of 1974—the statutory authority used during the first Trump administration to impose tariffs on goods imported from China—affords the U.S. Trade Representative (USTR) the power to commence investigations into any acts, policies, and practices of a foreign country that are unreasonable or discriminatory and burden or restrict U.S. commerce.
Investigation into Excess Capacity and Production in the Manufacturing Sector
On March 11, 2026, United States Trade Representative Jamieson Greer announced the initiation of Section 301 investigations that will examine structural excess capacity and production in the manufacturing sectors of 16 economies to determine whether those economies' large or persistent trade surpluses, or their underutilized or unused capacity, are impacting U.S. domestic production and causing the United States to fall behind foreign competitors.
The economies subject to investigation are China, the European Union, Singapore, Switzerland, Norway, Indonesia, Malaysia, Cambodia, Thailand, Korea, Vietnam, Taiwan, Bangladesh, Mexico, Japan, and India.
The Federal Register Notice asserts that many U.S. trading partners are producing more goods than they can consume domestically. This overproduction is said to displace existing U.S. domestic production and prevent investment and expansion in U.S. manufacturing production. As a result, this presents a challenge to the administration's "efforts to re-shore supply chains and provide good-paying jobs for American workers." USTR also provided an illustrative list of sectors plagued by excess capacity and production, which includes aluminum, automobiles, batteries, cement, chemicals, electronics, energy goods, glass, machine tools, machinery, non-ferrous metals, paper, plastics, processed food and beverages, robotics, satellites, semiconductors, ships, solar modules, steel, and transportation equipment.
Investigation into Forced Labor Practices
On March 12, 2026, the United States Trade Representative initiated additional Section 301 investigations into 60 countries related to their alleged failure to impose and enforce a ban on the importation of goods produced with forced labor. Ambassador Greer stated that American workers and firms "have been forced to compete against foreign producers who may have an artificial cost advantage gained from the scourge of forced labor."
The Federal Register Notice highlights specific inputs produced by forced labor for downstream goods, including cotton, textiles, palm fruit for cooking oils and biofuels, fish used to produce fish oil and fish meal, and critical minerals used to produce solar products and auto parts.
The impacted countries include Algeria, Angola, Argentina, Australia, the Bahamas, Bahrain, Bangladesh, Brazil, Cambodia, Canada, Chile, China, Colombia, Costa Rica, the Dominican Republic, Ecuador, Egypt, El Salvador, the European Union, Guatemala, Guyana, Honduras, Hong Kong, India, Indonesia, Iraq, Israel, Japan, Jordan, Kazakhstan, Kuwait, Libya, Malaysia, Mexico, Morocco, New Zealand, Nicaragua, Nigeria, Norway, Oman, Pakistan, Peru, Philippines, Qatar, Russia, Saudi Arabia, Singapore, South Africa, South Korea, Sri Lanka, Switzerland, Taiwan, Thailand, Trinidad and Tobago, Türkiye, United Arab Emirates, the United Kingdom, Uruguay, Venezuela, and Vietnam.
Opportunities for Hearings and Comments
On May 5, 2026, following the investigations into excess industrial capacity and production, the Section 301 Committee will hold public hearings to discuss any subsequent findings and determinations at the U.S. International Trade Commission (USITC) beginning at 10:00 a.m. and continuing as necessary until May 8, 2026. The USTR will also open dockets for submission of written comments and requests to appear at the hearings on March 17, 2026. To ensure consideration, all comments and requests should be submitted by April 15, 2026, at 11:59 p.m.
For the Section 301 forced labor investigations, the Section 301 Committee will hold public hearings beginning on April 28, 2026 at 10:00 a.m., and continuing as necessary, until May 1, 2026. The dockets for submission of written comments and requests to appear at the hearings opened on March 12, 2026, at 9:45 p.m., and the deadline to submit is April 16, 2026.
