From Factory Floor to Shopping Cart: A Practitioner's Guide to Tracing Forced Labor in US Corporate Supply Chains

The sneakers on a warehouse shelf in Ohio. The solar panels on a suburban rooftop in California. The shrimp in a grocery store freezer case in Georgia. Each of these products carries with it a supply chain — a sequence of extraction, processing, manufacturing, and logistics that may span a dozen countries and involve hundreds of subcontractors before the item reaches an American consumer. And somewhere along that chain, in a significant number of cases, there is documented evidence of forced labor.

For advocates, researchers, and consumers who want to act on that evidence, the challenge has historically been one of access: How do you find the data? How do you interpret it? And once you have it, how do you turn it into leverage?

This guide is designed to answer those questions in practical terms.

Understanding the Landscape: What "Forced Labor" Means in Supply Chain Context

Before reaching for databases, it helps to understand what investigators are actually looking for. The International Labour Organization defines forced labor as work extracted under threat or coercion, where the worker cannot freely refuse or leave. In supply chain contexts, this encompasses a wide range of practices: debt bondage in fishing fleets, state-sponsored compulsory labor in agricultural harvests, document confiscation in migrant worker dormitories, and the systematic use of prison or internment camp labor in manufacturing.

In the US policy context, two legal frameworks are particularly relevant. The Tariff Act of 1930, as amended by the Trade Facilitation and Trade Enforcement Act of 2016, prohibits the importation of goods made with forced labor and empowers US Customs and Border Protection (CBP) to issue Withhold Release Orders (WROs) blocking specific shipments. More recently, the Uyghur Forced Labor Prevention Act (UFLPA), which took effect in June 2022, established a rebuttable presumption that goods produced in China's Xinjiang region — or by entities on a specific enforcement list — are made with forced labor, shifting the burden of proof onto importers.

These legal tools generate data. And that data is publicly accessible.

Tier One: Official Government Databases

CBP's Forced Labor Enforcement Actions US Customs and Border Protection maintains a public list of active Withhold Release Orders and Findings on its website. This list identifies specific companies, commodities, and countries of origin where CBP has determined that forced labor indicators are present. It is updated regularly and searchable by commodity type. For researchers, this is the most authoritative starting point — a federal agency's affirmative determination that a specific supply chain has a documented forced labor problem.

The UFLPA Entity List Administered by the Interagency Forced Labor Enforcement Task Force, the UFLPA Entity List names specific Chinese companies whose goods are presumed to have been produced with forced labor in Xinjiang. The list is publicly available through the Department of Homeland Security's website and is updated periodically as new evidence is reviewed. Checking whether a supplier appears on this list — or whether a brand's known suppliers have business relationships with listed entities — is a critical investigative step for anyone researching electronics, textiles, or polysilicon supply chains.

Department of Labor's List of Goods Produced by Child Labor or Forced Labor The DOL's Bureau of International Labor Affairs (ILAB) publishes an annual list — commonly known as the TVPRA List — identifying goods from specific countries with documented child labor or forced labor in their production. This resource is broader in scope than CBP's enforcement actions and covers agricultural commodities, mined materials, and manufactured goods across more than 70 countries. It is an essential reference for understanding systemic risk by sector and geography.

Tier Two: Civil Society and NGO Databases

Government databases capture only a fraction of documented forced labor risk. Civil society organizations have built a parallel infrastructure of investigative resources that often goes deeper and moves faster than official enforcement mechanisms.

KnowTheChain This benchmarking initiative evaluates major corporations in high-risk sectors — food and beverage, information and communications technology, and apparel — on their supply chain transparency and forced labor mitigation practices. Scores are publicly available and searchable by company, allowing advocates to identify which brands are performing well and which are lagging. The benchmark reports also include narrative analysis of specific risk factors by sector.

Sheffield Hallam University's Supply Chain Research The Helena Kennedy Centre at Sheffield Hallam has produced some of the most rigorous academic mapping of forced labor in specific global supply chains, including landmark reports on cotton from Xinjiang and on labor practices in the Brazilian beef industry. These reports are freely downloadable and provide detailed commodity-level analysis that can anchor broader advocacy campaigns.

Global Slavery Index Published by the Walk Free Foundation, the Global Slavery Index provides country-level estimates of modern slavery prevalence alongside vulnerability assessments and government response ratings. While its methodology has been subject to scholarly debate, it remains a widely cited reference for establishing baseline risk profiles in specific geographies.

Tier Three: Corporate Disclosure Documents

One of the most underutilized investigative resources available to US-based researchers is the corpus of corporate disclosure documents that companies are required or incentivized to produce.

California Transparency in Supply Chains Act (CTSCA) Disclosures Since 2012, large retailers and manufacturers doing business in California have been required to disclose their efforts to eradicate slavery and human trafficking from their supply chains. These disclosures — which companies typically publish on their own websites — vary enormously in quality and specificity, and that variation is itself informative. A company that discloses nothing beyond a boilerplate paragraph is communicating something meaningful about its priorities.

SEC Filings For publicly traded companies, Securities and Exchange Commission filings — particularly annual 10-K reports — sometimes contain supply chain risk disclosures, especially following the enactment of the UFLPA. Searching EDGAR, the SEC's public filing database, for specific company filings and then conducting keyword searches for terms like "Xinjiang," "forced labor," or "supply chain risk" can surface disclosures that companies have not prominently publicized.

Sustainability and ESG Reports Almost every major US corporation now publishes an annual sustainability or environmental, social, and governance (ESG) report. These documents are voluntary and self-reported, which means they require critical reading — but they also often contain supplier lists, audit summaries, and risk assessments that provide entry points for deeper investigation.

Turning Data Into Action: Advocacy Applications

Data is only as valuable as the advocacy it enables. Once a researcher has established a documented connection between a specific brand and a forced labor risk, several pathways exist for applying pressure.

Shareholder engagement. For publicly traded companies, shareholder resolutions on supply chain transparency have become an increasingly effective tool. Organizations like As You Sow maintain databases of pending and historical shareholder actions on human rights issues.

Regulatory complaints. Advocates can file formal petitions with CBP requesting a Withhold Release Order against specific goods. The agency's petition process is publicly documented and has resulted in enforcement actions initiated by civil society organizations.

Procurement leverage. Many US state and municipal governments have adopted responsible procurement policies that prohibit purchasing goods with documented forced labor in their supply chains. Connecting investigative findings to procurement officials can translate research into purchasing policy.

Consumer campaigns. While consumer pressure alone is rarely sufficient to drive structural change, it can be a meaningful complement to regulatory and shareholder strategies — particularly when campaigns are grounded in specific, verifiable evidence rather than generalized claims.

A Note on Methodological Integrity

Forced labor documentation carries real stakes for real people. Investigators working in this space have an obligation to distinguish between documented evidence and inferred risk, to apply consistent evidentiary standards across different geographies and industries, and to be transparent about the limitations of available data. Supply chain opacity is a feature, not a bug, of the global trading system — and that opacity means that even the best-resourced investigations work with incomplete information.

The tools catalogued here will not give any researcher a complete picture. What they will provide is a defensible evidentiary foundation — one that can support credible advocacy, meaningful journalism, and evidence-based policy engagement. In a system designed to obscure, that foundation matters enormously.
