Uyghur Forced Labor Prevention Act (UFLPA)

The Uyghur Forced Labor Prevention Act (UFLPA), signed December 23, 2021 (P.L. 117-78), creates a rebuttable presumption that all goods mined, produced, or manufactured wholly or in part in China's Xinjiang Uyghur Autonomous Region, or by entities on the UFLPA Entity List, are made with forced labor and are therefore prohibited from importation into the United States under 19 U.S.C. § 1307 — the longstanding ban on importing goods made with convict, forced, or indentured labor. The statutory presumption is powerful: CBP can detain any shipment suspected of containing Xinjiang-origin goods, and the burden falls entirely on the importer to prove by "clear and convincing evidence" that the goods were not made with forced labor. If the importer cannot meet this burden, the goods are excluded. The UFLPA addresses the Chinese government's documented mass detention and forced labor of Uyghurs and other Muslim minorities in Xinjiang. It complements Section 301 tariffs and export controls as part of the broader U.S. trade and national security response to China. — a region that produces approximately 85% of China's cotton, 35% of the world's polysilicon (used in solar panels), and significant shares of tomatoes, peppers, and other agricultural goods. The Act established an interagency Forced Labor Enforcement Task Force (FLETF) and required DHS to publish and maintain the UFLPA Entity List — a list of companies in Xinjiang supply chains linked to forced labor.

Current Law (2026)

Legal Authority

• 19 U.S.C. § 1307 — Forced labor import prohibition: goods produced in whole or in part by convict, forced, or indentured labor (including forced child labor) are prohibited from entry into the U.S.; CBP enforces through Withhold Release Orders (WROs) — detaining shipments — and Findings (formal determination that a specific entity's goods are produced with forced labor, barring import)
• UFLPA § 3 — Rebuttable presumption: all goods from Xinjiang or from Entity List entities are presumed to be produced with forced labor under § 1307; the importer may rebut the presumption only with clear and convincing evidence that the goods were not made with forced labor, combined with a complete supply chain tracing showing no Xinjiang-origin inputs at any tier
• UFLPA § 2 — Interagency coordination: established the Forced Labor Enforcement Task Force (FLETF), chaired by the Secretary of Homeland Security, with members from USTR, State, Labor, Commerce, Treasury, and DOJ; FLETF coordinates enforcement strategy and maintains the Entity List
• UFLPA § 4 — UFLPA Entity List: DHS must publish (and update) a list of (a) entities in Xinjiang that mine/produce/manufacture goods with forced labor, (b) entities working with Xinjiang government to transfer labor or source goods, and (c) entities exporting goods produced with forced labor from Xinjiang; goods from Entity List entities are barred — no rebuttal permitted
• UFLPA § 5 — Congressional reporting: DHS and FLETF must report to Congress on enforcement actions, Entity List additions, and supply chain guidance
• 19 U.S.C. § 1307 (prior Withhold Release Orders): Before UFLPA, CBP had separately issued WROs against specific Xinjiang entities (cotton, polysilicon, tomatoes); UFLPA supersedes and extends these by creating a region-wide presumption rather than entity-specific orders

How It Works

Unlike traditional customs enforcement (where CBP bears the burden of proving non-compliance), UFLPA flips the burden entirely to the importer (UFLPA § 3). Once CBP identifies a shipment as potentially containing Xinjiang-origin goods — through targeting algorithms, prior detentions, tips, or supply chain data — the shipment is detained and the importer must actively prove the goods are clean with "clear and convincing evidence." This "guilty until proven innocent" structure was a deliberate legislative choice to address the evidentiary difficulty of proving labor conditions deep in Chinese supply chains. Rebutting the presumption requires complete supply chain tracing to the origin of every input: for a solar panel, that means documenting polysilicon origin → wafer manufacturer → cell manufacturer → module manufacturer → panel exporter; for cotton apparel, tracing fiber origin (which ginning facility, which farm) → spinning mill → fabric mill → cut-and-sew → brand. DHS guidance requires complete supply chain mapping with documentation at each tier, responses to all CBP requests for information and attestations, and proof the goods were not manufactured with forced labor (audit reports, labor certifications, or government-issued certificates); for polysilicon specifically, third-party audits using Responsible Business Alliance (RBA) standards are required.

The UFLPA Entity List (§ 4), published and updated by DHS, names companies in Xinjiang supply chains linked to forced labor — goods from Entity List companies are absolutely barred with no rebuttal mechanism available. The sectors most affected reflect Xinjiang's role in global supply chains: Xinjiang produces approximately 35% of the world's polysilicon, meaning most Chinese solar panels are affected (with significant implications for U.S. clean energy deployment timelines); it produces 85% of China's cotton, affecting virtually all cotton apparel from China and leading to CBP detentions of major global brand shipments; it is a major Chinese tomato producer (tomato paste and processed products); and some coal-to-chemicals and rare earth processing has been flagged. Over 9,000 shipments have been detained since the law's effective date in June 2022.

How It Affects You

If you are an importer of solar panels, apparel, or other China-origin goods: Assume UFLPA scrutiny is a routine cost of doing business with China-origin goods. Work backward from your finished product to trace every material input: cotton fiber, polysilicon, aluminum frames, encapsulant, backsheets. Engage a supply chain audit firm now — waiting until CBP detains a shipment is too late. CBP's online importer guidance at cbp.gov/uflpa describes what documentation is required at each tier. For solar specifically, the Solar Energy Industries Association (SEIA) at seia.org maintains guidance on documentation standards. The FLETF's Operational Guidance document (available at dhs.gov/uflpa) is the authoritative source for acceptable evidence. Build documentation systems before shipping; retroactive documentation is very difficult to assemble under a CBP deadline.

If you are a solar developer, installer, or utility: UFLPA enforcement has directly constrained solar panel supply. Panels sourced from Chinese manufacturers that use Xinjiang polysilicon have been detained, delaying projects. The practical effect has been to push some buyers toward non-Chinese panel manufacturers (First Solar, which is U.S.-based with non-Xinjiang supply chains; Korean and Southeast Asian manufacturers with documented clean supply chains). As you sign PPAs and plan procurement, factor UFLPA compliance into your supplier selection — a panel delayed at the port is a panel you're paying interest on while the project slips.

If you are a compliance, ESG, or supply chain professional: UFLPA has transformed Tier 2+ supply chain visibility from a nice-to-have to a legal compliance requirement. The tools that exist for this — Sourcemap, Assent, TrusTrace, Heco (for cotton DNA tracing), and First Mode (for minerals) — have seen significant adoption increases. Budget for supply chain mapping and ongoing monitoring. Document your methodology: even if CBP never detains your shipment, investors, downstream customers, and lenders are increasingly asking for supply chain forced labor due diligence documentation as part of ESG reporting.

If you are a domestic manufacturer competing against Chinese imports: UFLPA creates an asymmetric enforcement burden on your competitors who source from China. Chinese apparel manufacturers, solar panel makers, and agricultural processors face real compliance costs and the risk of detained shipments. If your competitors' goods are being detained and yours are moving freely, document the trade disruption for potential exclusion extension or AD/CVD petition purposes. UFLPA is not designed as a trade remedy, but its practical effect on Chinese import competitiveness is real.

State Variations

UFLPA is exclusively federal. No state variations. California, however, has its own supply chain transparency law (CA Transparency in Supply Chains Act, SB 657) requiring large retailers to disclose supply chain forced labor efforts — a separate state obligation that parallels federal UFLPA compliance.

Implementing Regulations

• 19 CFR Part 12 — CBP regulations on restricted merchandise; UFLPA enforcement operates under CBP's existing detained shipment procedures
• DHS UFLPA Operational Guidance for Importers (published by FLETF; available at dhs.gov/uflpa) — the authoritative administrative guidance on what documentation is required to rebut the presumption
• FLETF UFLPA Entity List — Published and updated at dhs.gov/uflpa-entity-list

Pending Legislation

• UFLPA Extension and Enhancement Act — Proposals to expand UFLPA coverage beyond Xinjiang to other regions of China where forced labor has been documented, and to clarify the evidentiary standard
• Solar supply chain provisions — Multiple energy and trade bills include provisions related to UFLPA enforcement for solar panels and the interaction with clean energy tax credits (IRA solar credit eligibility conditioned on UFLPA compliance)
• Critical minerals provisions — Proposals to apply UFLPA-like presumptions to critical minerals and battery materials from specific adversary countries

Recent Developments

• CBP has detained over 9,000 shipments under UFLPA since its June 2022 effective date; the total value of detained goods runs into the billions; a significant share of detained shipments have been refused entry after failure to rebut the presumption
• The FLETF added additional companies to the UFLPA Entity List in 2024–2025, including several major Xinjiang aluminum producers and a polysilicon supplier; Entity List additions have immediately disrupted supply chains for importers using those suppliers
• The intersection of UFLPA and clean energy policy has created significant policy tension: the Inflation Reduction Act's solar manufacturing incentives require domestic solar supply chains, but UFLPA's enforcement has constrained Chinese panel supply, raising clean energy costs; Congress and the administration have been managing this tradeoff
• CBP published expanded guidance in 2025 clarifying acceptable evidence for polysilicon (requiring RBA EICC-GeSI compliant third-party audits) and cotton (accepting DNA cotton fiber testing where available)
• The Biden and Trump administrations have both maintained robust UFLPA enforcement, reflecting bipartisan consensus on Xinjiang human rights concerns; the issue is one of the few areas of U.S.-China policy with consistent cross-party support
