The United States brought together more than 50 nations in Washington on Monday to teach them how to build and run systems for blocking goods made with forced labor — a move that marks a fundamental shift in how forced-labor compliance risk lands on the technology and semiconductor industries. USTR’s September 15 training was organized by the Office of the United States Trade Representative, joined by the Departments of Homeland Security and Labor and U.S. Customs and Border Protection.

Until now, the compliance question for a tech manufacturer sourcing polysilicon for solar panels or cobalt for lithium-ion batteries was essentially unilateral: would U.S. Customs and Border Protection flag the shipment? That calculus is about to involve dozens of customs agencies at once. A supply chain that routes Xinjiang-origin materials through Vietnam, Bangladesh, or Cambodia can no longer rely on a single enforcement chokepoint. If those intermediate countries build the import screening regimes the U.S. is now offering to install, the compliance calculus becomes multiplicative rather than additive.

Washington Deploys a Carrot After Using the Stick

The training session arrived seven weeks after the Trump administration’s forced-labor tariffs — 10% to 12.5% on imports from 60 economies covering approximately 99.4% of all U.S. goods imports — took effect at 12:01 a.m. EDT on July 24, 2026, immediately replacing Section 122 duties that expired the same moment. Greenberg Traurig confirmed the Section 301 July 23 final action in its trade analysis.

The sequence leading to those tariffs was methodical. USTR initiated 60 Section 301 investigations on March 12, 2026, drawing more than 450 written comments and nearly 60 witnesses over two days of public hearings in late April. On June 2, USTR found all 60 economies actionable, having either failed to adopt a legal prohibition on forced-labor imports or failed to enforce one that already existed. The agency proposed tariffs of 10% to 12.5%, held a second round of public hearings in July — this time with more than 100 witnesses — and finalized the action on July 23.

Monday’s training workshop, however, signals a shift in emphasis. The administration has demonstrated its willingness to impose tariffs; it is now offering a clear path off the list. Adopt a credible forced-labor import prohibition, enforce it, and the punitive duties can be reduced or removed. As of the session, a number of countries had already taken that path.

Who Acted — and the Difference Between a Law and an Enforcement Operation

USTR’s press release confirmed that by July 2026, a dozen economies had adopted measures prohibiting the importation of goods made with forced labor: Cambodia, Canada, Ecuador, the European Union, Guatemala, Honduras, India, Indonesia, Mexico, Pakistan, Sri Lanka, and Trinidad and Tobago. Since the tariffs took effect, dozens more countries have expressed interest in adopting similar measures, according to USTR.

India’s case demonstrates both the effectiveness of the tariff pressure and the granular operational work that follows. Originally facing a 12.5% rate, New Delhi moved quickly in mid-July 2026: India’s Directorate General of Foreign Trade amended its Foreign Trade Policy on July 13, 2026, inserting a prohibition on importing goods produced wholly or in part through forced labor — with the definition drawn from the International Labour Organization’s Forced Labour Convention of 1930. The move qualified India for the lower 10% duty tier under the final USTR order.

Yet USTR’s June 2026 report had already flagged six economies — Canada, Ecuador, the EU, Indonesia, Mexico, and Pakistan — as having formal prohibitions on the books but failing to enforce them meaningfully. All six remained subject to tariffs. That gap between having a law and running a functional import-enforcement operation is precisely what Monday’s training is designed to close.

The ILO defines forced or compulsory labor as work exacted from any person under the threat of a penalty and for which the person has not voluntarily offered themselves. The ILO estimated that approximately 28 million people globally were in forced labor as of 2021, an increase of 2.7 million from 2016.

How Xinjiang Inputs Move Through the World’s Supply Chains

The entire initiative’s logic depends on understanding a documented evasion pattern that USTR’s June 2026 report described explicitly: Chinese inputs raising forced-labor concerns are exported to third countries, processed into finished goods, and then shipped onward to the United States — effectively obscuring the origin of the tainted material.

The report found that nearly every one of the 60 investigated economies had imported cotton from China at some point between 2021 and 2025 — a finding that strongly suggests forced-labor inputs from Xinjiang were entering global supply chains through intermediate processing steps in countries that had no legal obligation to screen them out.

The Uyghur Forced Labor Prevention Act, signed into law December 2021 and effective June 2022, already established a rebuttable presumption that any goods manufactured wholly or in part in Xinjiang are made with forced labor and therefore banned from U.S. import — unless an importer can demonstrate otherwise by clear and convincing evidence. But the burden remains on U.S. CBP alone to catch evasion. A country that has no such prohibition at its own border cannot serve as a barrier in the supply chain — which is why the September 15 training aims to build that barrier in dozens of additional countries.

What This Means for Polysilicon, Cobalt, and Critical Minerals

The implications for the technology industry extend well beyond cotton and apparel. The critical inputs that power modern semiconductors, solar panels, and electric vehicle batteries carry some of the same forced-labor risks that prompted the UFLPA’s polysilicon enforcement priority.

Approximately 35% to 45% of the world’s solar-grade polysilicon — the material used to manufacture solar panels and, in a different purity grade, semiconductor wafers — originates from Xinjiang. CBP has designated polysilicon as a high-priority enforcement area under the UFLPA, and multiple Chinese solar companies appear on the UFLPA Entity List, including companies added in January 2025.

The semiconductor industry’s relationship to polysilicon is more complex. The Semiconductor Industry Association testified in 2022 that semiconductor-grade polysilicon — which requires purity levels far exceeding what Xinjiang producers currently manufacture — is concentrated among five companies: Wacker Chemie in Germany, Hemlock Semiconductor in the United States, Tokuyama Corporation in Japan, Mitsubishi Corporation in Japan, and REC Silicon based in Norway. The chip polysilicon supply chain carries substantially lower forced-labor risk than the solar supply chain.

Cobalt presents a different profile. The Democratic Republic of Congo produces approximately two-thirds of the world’s cobalt. An estimated 15% to 30% of that cobalt comes from artisanal mining operations where, as of 2022, child and forced labor have been extensively documented. An estimated 40,000 children work in hazardous conditions in DRC cobalt mines, according to EU agency estimates. Fifteen of nineteen DRC cobalt mines are owned or financed by Chinese companies, according to Congressional research.

Lithium, sourced primarily from Australia, Chile, and Argentina — countries that are subject to the new tariff regime — involves its own labor monitoring challenges, though the forced-labor risk profile is generally lower than in artisanal cobalt or Xinjiang polysilicon.

ArentFox Schiff’s 2026 forced-labor compliance guide predicted that “regulators will continue to focus on automotive manufacturers, the electronics industry, critical minerals supply chains, and steel and aluminum processors,” with new targets including electric vehicles and battery supply chains. The firm noted that international enforcement coordination would accelerate, citing a likely resurgence of enforcement activity following a period in which UFLPA enforcement had been de-prioritized while other trade priorities dominated CBP’s attention.

Supply chain compliance data firm Sayari estimated that electronics imports carry the highest forced-labor risk across G20 nations, representing $243.6 billion in imports at risk.

How Does a Forced-Labor Import Ban Actually Work?

Effective forced-labor import screening requires more than a legal prohibition. The countries that attended Monday’s session were receiving practical training from U.S. agencies that have spent years building the enforcement architecture — the evidentiary standards for rebuttable presumptions, the customs documentation requirements, the interagency coordination with labor and homeland security officials, and the supply chain tracing methodology that can follow a material from an ore deposit in Xinjiang to a finished module in a third country.

That architecture takes time to build. USTR acknowledged that Monday’s session would be accompanied by in-depth, country-specific technical assistance for economies that request it — an indication that training is a starting point rather than a solution. The gap between adopting a legal prohibition and actually running a functioning enforcement regime is well-documented: six of the 60 investigated economies had formal prohibitions yet remained on the tariff list because USTR determined they were not enforcing them effectively.

The Global Electronics Association responded to the July 2026 tariff action by signaling support for the administration’s objective. “Forced labor has no place in the electronics supply chain,” the trade group stated, noting that member companies had developed IPC-1401, the supply chain social responsibility standard, and participate in the Responsible Business Alliance Validated Assessment Program. The association also sought exemptions for semiconductor manufacturing equipment, which USTR preserved in the final action.

Lawsuits Are Already Testing Whether the Tariffs Hold

The enforcement campaign now faces legal challenge. Two separate complaints have been filed at the Court of International Trade.

The Liberty Justice Center filed a complaint on July 24, 2026 — the same day the tariffs took effect — on behalf of Burlap & Barrel, Inc. and Collective Horology LLC as a proposed class action, arguing that USTR exceeded its authority, that similar duty rates were applied arbitrarily across products with no apparent connection to forced labor, and that the tariffs exceeded the scope of Section 301. The Liberty Justice Center is the same organization that successfully challenged the IEEPA tariffs before the Supreme Court.

On August 3, 2026, the attorneys general of 25 states — led by Oregon, Arizona, and California — filed a complaint at the Court of International Trade, alleging the tariffs are “ultra vires, arbitrary, capricious and contrary to law.” This complaint joined others pending before the CIT.

Legal analysts who have studied the proceedings are divided on the tariffs’ durability. Trade attorney Joshua Kagan of Kelley Drye noted that while critics may credibly argue the investigation was pretextual for continuing the broader tariff agenda, Kagan said both propositions can be simultaneously true — an investigation can be pretextual and also based on actual evidence with the agency following necessary administrative steps. He added that Section 301 tariffs are more difficult to challenge than IEEPA tariffs because “not only does 301 authorize duties, it has a preference for duties.”

Ajay Srivastava of the Global Trade Research Initiative took a sharper view of the jurisdictional question, arguing the investigation “goes beyond the traditional scope of Section 301” because it targets whether countries prohibit imports made with forced labor in third countries — not whether those countries are themselves using forced labor — and that India should contest it as an attempt to impose U.S. import-control norms through unilateral action.

Does Scrutiny Make Supply Chains Cleaner — or Just Busier?

Whether the global supply chain emerges with genuinely stronger labor protections — or merely more paperwork — may depend on what happens in customs offices from Dhaka to Jakarta in the months ahead.

The training convened on September 15 offers a roadmap, and the tariff carrot-and-stick has already produced measurable movement: a dozen countries adopted new forced-labor import bans in the span of a few months, with dozens more expressing interest since July. But producing legally compliant documentation and actually removing forced-labor inputs from a supply chain are different things. The UFLPA’s experience is instructive: after more than four years of enforcement, a supply chain for solar polysilicon that is provably free of Xinjiang inputs remains difficult to build at scale, and the DRC cobalt sector remains without a verified clean supply chain at any meaningful volume.

Critical minerals compliance teams at tech manufacturers, semiconductor firms, and clean energy companies are watching Monday’s training as more than a diplomatic milestone. If the 50-plus countries in that room build functional enforcement regimes, the compliance question for a cobalt cathode or a polysilicon ingot will no longer be “will U.S. CBP flag this shipment?” It will be “will any one of dozens of newly equipped customs agencies flag it at some point along the route?” That is a structurally different question — and one the semiconductor and clean energy industries have not yet fully priced into their sourcing decisions.

Frequently Asked Questions

What countries are now subject to the forced-labor import tariffs, and can they get off the list?

The tariffs — 10% or 12.5% on top of normal import duties — apply to goods from 60 economies that USTR determined had either no legal prohibition on forced-labor imports or an unenforced one. Countries can move to the lower 10% tier, or potentially exit the tariff regime, by adopting and demonstrating effective enforcement of a credible forced-labor import prohibition. By July 2026, a dozen economies had already done so and qualified for reduced rates; the September 15 training is designed to help additional countries build the enforcement infrastructure needed to follow suit.

How do these tariffs and the USTR training affect tech companies sourcing critical minerals?

Tech and clean energy companies that source polysilicon for solar panels, cobalt for batteries, or other critical minerals through supply chains that touch high-risk regions — particularly Xinjiang and the DRC — face compounding compliance pressure. As more countries build their own forced-labor import screening systems, a supply chain that only had to pass U.S. CBP inspection now needs to pass the scrutiny of any intermediate country in the processing chain that has an import ban. That multiplicative enforcement exposure raises the bar for supply chain tracing and documentation well beyond what U.S.-only enforcement required.

Are the Section 301 forced-labor tariffs likely to survive legal challenge?

Two sets of lawsuits have been filed at the Court of International Trade since the tariffs took effect on July 24, 2026. Legal analysts generally rate Section 301 as more durable than the IEEPA tariffs that the Supreme Court invalidated in February 2026, because Section 301 explicitly authorizes duties and required a formal public record — hearings, written comments, government determinations — before imposition. That said, the unprecedented breadth of the action (60 countries, covering 99.4% of U.S. imports) may expose the tariffs to “arbitrary and capricious” challenges. The outcome of the pending litigation is uncertain.

What is third-country circumvention, and why is it the central problem this campaign is trying to solve?

Third-country circumvention refers to the practice of routing goods through intermediate countries to disguise the origin of inputs that are subject to trade restrictions. In the forced-labor context, it typically works like this: polysilicon produced with forced labor in China’s Xinjiang region is shipped to Vietnam, Cambodia, or Bangladesh, where it is incorporated into solar panels or other products. Those finished goods then enter the U.S. labeled as Vietnamese or Bangladeshi — with no indication of Xinjiang-origin inputs. USTR’s June 2026 report found that nearly every one of the 60 investigated economies had imported Chinese cotton between 2021 and 2025, strongly suggesting the same dynamic was operating at scale in the apparel supply chain. The entire rationale for training 50+ countries to build their own import bans is that the mechanism can only be disrupted if each link in the supply chain has its own screening capacity.
