If an investigation returns an affirmative finding, the Trade Representative is authorized to impose tariffs, import restrictions, or both. The same legal authority was used to levy duties on Chinese goods during Trump’s first term, and these investigations come directly on the heels of a U.S. Supreme Court ruling in February 2026 that invalidated tariffs previously imposed under a separate authority: The International Emergency Economic Powers Act.
This is not a targeted action against one country or one sector. Sixty economies. Ninety-nine percent of U.S. import volume. The scope alone signals that the administration intends these investigations as a structural trade policy tool, not a diplomatic signal.
The scale of the problem they are responding to is real. The International Labour Organization (ILO) estimates that as of 2021, 28 million people globally are in forced labor. This is an increase of 2.7 million since 2016, driven entirely by the private economy. Annual profits from forced labor in the global private economy were estimated at $63.9 billion in 2024. Firms using forced labor incur artificially lower costs, which skews competitive conditions against companies that do not.
The U.S. has prohibited the importation of goods produced with forced labor for nearly 100 years. What is new is the enforcement mechanism: using Section 301 to compel trading partners to adopt and enforce equivalent import bans of their own or face retaliatory trade measures.
For companies with complex, multi-country supply chains, the immediate priority is exposure mapping. The Department of Labor’s 2024 TVPRA List already identifies 134 products produced with forced labor in specific countries — and 34 downstream goods made with forced labor inputs. Those inputs include cotton used in garments and textiles, critical minerals used in solar products and auto parts, fish used in fish oil and fish meal, and palm fruit used in cooking oils and biofuels.
U.S. Customs and Border Protection currently has dozens of withhold release orders and eight findings in effect, prohibiting entry of specific goods. That number is widely understood to understate the actual volume of goods in U.S. commerce with forced labor exposure.
Companies that have already been denied U.S. market entry for their goods and subsequently re-exported them to markets without equivalent bans are explicitly named in the Federal Register notice as a concern. If those third markets are now also under investigation, the arbitrage disappears.
USTR has signaled it intends to move these investigations on an expedited basis, with a target of being prepared to impose tariffs by around July 24, 2026. That is approximately four months from initiation to potential action. The comment and hearing window is narrow:
This is also running in parallel with a separate set of Section 301 investigations into industrial overcapacity across 16 economies, announced on March 10, 2026. Many of the same countries appear on both lists.
The comment period is the operative window. Companies with supply chain exposure in any of the 60 economies, which is most major importers, should assess whether to submit written comments or request time to testify. The USTR is specifically seeking input on which economies are already establishing forced labor import bans, whether existing prohibitions are being effectively enforced, and what scope of duties or import restrictions would be appropriate if action is taken.
For sustainability and compliance teams, this is also a forcing function on supply chain due diligence documentation. If an affirmative finding triggers restrictions, companies will need to demonstrate the provenance and compliance status of their supply chains, not after the fact, but now.
