Under the UFLPA, CBP presumes goods tied to Xinjiang or Entity List companies are made with forced labor and detains them — only about 6.5% of FY 2025 detentions were released. CBP also issues Withhold Release Orders (WROs) against specific factories worldwide under 19 U.S.C. § 1307, including two Jordanian garment producers in June 2026.
What the UFLPA Is and Why It Matters to Every Importer
The Uyghur Forced Labor Prevention Act was signed into law in December 2021 and took effect on June 21, 2022. It is the most powerful forced labor trade enforcement tool in U.S. history, and it fundamentally changed the burden of proof for imports connected to China's Xinjiang Uyghur Autonomous Region (XUAR).
Before the UFLPA, CBP had to prove that specific goods were produced with forced labor before it could detain them. The UFLPA flipped that standard entirely. Now, any goods that CBP suspects have a connection to the XUAR or to entities on the UFLPA Entity List are presumed to be produced with forced labor unless the importer proves otherwise.
The standard of proof is "clear and convincing evidence," which is an extraordinarily high bar. Generic supplier certifications, form letters, and basic invoices are not sufficient. CBP requires comprehensive documentation tracing the complete supply chain from raw materials through finished goods, including purchase orders, production logs, shipping records, certificates of origin, and laboratory test results.
The UFLPA Entity List, maintained by the Forced Labor Enforcement Task Force (FLETF), now includes 144 entities spanning multiple industries and located across the XUAR and other Chinese provinces. Goods produced by these entities, or goods containing any inputs from these entities, are automatically subject to the rebuttable presumption.
The Numbers That Should Change How You Think About Compliance
Since the UFLPA took effect, CBP has reviewed more than 18,000 shipments with an aggregate value of approximately $3.81 billion. Enforcement volume peaked in fiscal year 2025, when CBP stopped roughly 7,325 shipments for UFLPA review, more than 50% above the prior year.
The release rate tells the real story. Only about 6.5% of shipments stopped in FY 2025 were ultimately released into U.S. commerce. When earlier years are included, the overall release rate since the UFLPA's implementation has dropped to approximately 35%, and under the current enforcement posture it is trending lower.
What this means in practical terms: if your shipment is detained under the UFLPA, the overwhelming likelihood is that it will not be released. Your goods will either be excluded (denied entry and returned or destroyed) or you will face a prolonged, expensive process of submitting documentation that may or may not result in release.
The financial impact of a detention goes far beyond the value of the goods themselves. While your shipment sits at the port, you are paying storage and demurrage charges that accumulate daily. Your customers are waiting for product that is not arriving. Your working capital is locked in inventory you cannot sell. And if you have contractual delivery obligations, missed deadlines can trigger penalties or lost accounts.
What Triggers a UFLPA Detention
CBP's targeting systems evaluate imports against several risk indicators. Understanding what draws scrutiny helps you assess your own exposure.
Direct sourcing from the XUAR. Any product mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region is automatically subject to the rebuttable presumption. This is the most straightforward trigger.
Sourcing from UFLPA Entity List companies. If any entity in your supply chain, at any tier, appears on the Entity List, the goods are presumed to be produced with forced labor. The list is updated regularly as new entities are identified.
High-risk product categories. CBP and the FLETF have identified priority sectors for enforcement. These include solar panels and components containing polysilicon (Xinjiang dominates global polysilicon production), cotton textiles, apparel, and yarn at any stage of processing (Xinjiang produces approximately 85% of China's cotton), tomato products including paste, sauce, and canned tomatoes, electronics components containing silica-based materials, lithium-ion batteries and energy storage systems, PVC products, automotive castings and components, and certain metals and minerals including lithium, graphite, cobalt, and nickel.
Commingled supply chains. Even if your specific goods do not originate in Xinjiang, if they contain inputs that were commingled during production with materials suspected of being manufactured using forced labor, the shipment is subject to detention. This is particularly relevant for commodity products where raw materials from multiple origins are blended during processing.
Sub-tier supplier connections. CBP is increasingly scrutinizing what happens below Tier 1 suppliers. The agency looks at where raw materials are mined, where they are refined and processed, and where they are converted into production inputs, particularly when those activities occur in China or involve entities with known or suspected ties to forced labor. Historic sourcing relationships are also considered.
The UFLPA Does Not Only Apply to Chinese Goods
This is a critical point that many importers miss. The UFLPA applies to any product that contains inputs or components sourced from the XUAR or from Entity List companies, regardless of where the final product is assembled.
A garment sewn in Vietnam using cotton yarn spun from Xinjiang cotton is subject to the UFLPA. A solar panel assembled in Malaysia using polysilicon produced in the XUAR is subject to the UFLPA. An automotive part manufactured in Mexico using aluminum processed by an Entity List company is subject to the UFLPA.
The country on your commercial invoice is not what determines UFLPA applicability. The origin of every significant input in your product is what matters. Importers who source from Vietnam, India, Mexico, or any other country are not immune if their supply chains include Chinese components or raw materials with Xinjiang connections.
CBP has flagged shipments from multiple countries including Malaysia, Cambodia, Vietnam, Thailand, India, Bangladesh, the Philippines, and Nicaragua under forced labor enforcement actions. The enforcement net is wide and getting wider.
Withhold Release Orders: Forced-Labor Enforcement Beyond the UFLPA
The UFLPA is not CBP's only forced-labor tool. Under 19 U.S.C. § 1307, CBP issues Withhold Release Orders against specific producers, factories, vessels, or regions anywhere in the world when information reasonably indicates their goods are made with forced labor. Once a WRO takes effect, CBP detains covered goods at every U.S. port of entry.
The June 2026 Jordan garment WROs show how fast this risk lands outside China. On June 23, 2026, CBP issued Withhold Release Orders against garments produced in Jordan by Needle Craft Ltd. and Casual Wear Apparel L.L.C. — the agency's fifth and sixth WROs of the fiscal year. CBP cited seven International Labour Organization indicators of forced labor at the factories: retention of identity documents, excessive overtime, intimidation and threats, physical and sexual violence, withholding of wages, restriction of movement, and abusive living and working conditions. Public trade and supplier records have connected these factories to major American apparel brands, which means downstream importers who never chose these factories directly are now carrying detained-shipment risk.
| WRO (19 U.S.C. § 1307) | UFLPA | |
|---|---|---|
| Who it targets | Named producers, factories, vessels, or regions — anywhere in the world | Goods connected to Xinjiang (XUAR) or UFLPA Entity List companies, at any supply-chain tier |
| Legal effect | Detention of covered goods at all U.S. ports | Rebuttable presumption that goods are made with forced labor |
| How you respond | Prove admissibility under 19 C.F.R. § 12.43 or export the goods, within three months after the date of importation | Applicability or exception review with clear and convincing evidence |
| Where you respond | CBP Forced Labor Portal — mandatory for all submissions since January 21, 2026 | |
What to do if your shipment is detained under a WRO
You have three options: export the goods, destroy them, or contest the detention by proving they were not made with forced labor. Contesting requires a certificate of origin under 19 C.F.R. § 12.43, a detailed importer statement, and complete supply-chain tracing from raw material to finished garment — including sub-tier and indirect suppliers. A standard commercial certificate of origin alone will not carry the burden, and the roughly three-month window is the worst possible time to start assembling documentation you do not already have.
The proactive version costs far less: screen every supplier — including the factories your vendors subcontract to — against both CBP's active WRO list and the UFLPA Entity List before goods ship, and keep the tracing package ready. Forced-labor exposure is also becoming a tariff question: USTR's final Section 301 forced-labor tariffs took effect July 24, 2026 across 60 economies — see our guide to the final Section 301 forced-labor action.
The New Forced Labor Portal
Effective January 21, 2026, CBP requires all importers to use the Forced Labor Portal to submit UFLPA-related reviews and documentation. The Portal serves as the centralized platform for applicability reviews (demonstrating that your goods are not connected to the XUAR or Entity List), requests for exception to the rebuttable presumption, admissibility reviews for goods detained under Withhold Release Orders, and CAATSA exception requests.
This mandatory portal replaces the previous informal submission process. Importers who have not registered for access should do so before a detention occurs, not after. Having the portal account, the submission process, and the documentation package prepared in advance can save critical days when a shipment is held.
How to Build a UFLPA Compliance Program
1. Map Your Full Supply Chain
Do not stop at Tier 1. Identify every entity involved in the production of your goods, from raw material extraction through final assembly. For each entity, document the company name, location, role in production, and the specific materials or components they supply. Screen every entity against the UFLPA Entity List.
This is the most labor-intensive step and the one most importers skip. It is also the one that determines whether your goods clear customs or sit at the port.
2. Collect and Maintain Documentary Evidence
For every tier of your supply chain, maintain purchase orders and contracts, commercial invoices and payment records, shipping and logistics documents (bills of lading, packing lists, freight records), production records and manufacturing logs, certificates of origin for raw materials, laboratory test results (particularly for cotton, polysilicon, and metals), and audit reports from third-party social compliance firms.
This documentation must demonstrate a clear, unbroken chain of custody from raw material to finished product. Gaps in documentation are treated as evidence that the supply chain cannot be verified.
3. Prepare a Detention Response Plan
Do not wait until goods are detained to figure out your response process. Build a plan now that includes the designated person responsible for managing a UFLPA detention, the process for accessing the Forced Labor Portal and submitting documentation, the location and organization of all supply chain documentation, the communication plan for notifying customers and logistics partners, and the criteria for deciding whether to contest the detention or re-export the goods.
CBP's published best practices indicate that the average review period for a complete documentation package is two to three weeks. But "complete" is the operative word. Incomplete packages cannot be reviewed, and the clock keeps running on storage charges.
4. Use Summary Tracing Reports for Repeat Shipments
If you have a supply chain that CBP has previously reviewed and cleared, you can significantly accelerate the review process for future shipments by providing a summary tracing report that identifies all suppliers and production stages along with a reference to the previously cleared supply chain. This approach allows CBP to quickly verify that the new shipment follows the same path as one already approved.
5. Audit Suppliers Regularly
Supply chains change. A supplier that was sourcing domestically last year may have switched to a cheaper input from Xinjiang this year. Annual supplier audits, combined with contractual requirements for suppliers to notify you of any sourcing changes, are the minimum standard for maintaining UFLPA compliance over time.
The Expanding Enforcement Landscape
UFLPA enforcement is not contracting. It is expanding in three directions simultaneously.
More product categories. Early enforcement focused on cotton, polysilicon, and tomato products. The scope has expanded to include lithium-ion batteries, automotive components, PVC, electronics, and critical minerals. Additional sectors could be added at any time as the FLETF identifies new risk areas.
More countries. New bilateral trade agreements signed by the U.S. with Malaysia, Cambodia, Vietnam, Thailand, and Bangladesh include provisions requiring these countries to implement their own forced labor import prohibitions. The global enforcement infrastructure for forced labor is growing, not just the U.S. apparatus.
More legal tools. The USMCA review is expected to strengthen forced labor enforcement provisions, including expanded use of the Rapid Response Labor Mechanism and broader application of forced labor import bans across North American supply chains. The final Section 301 action effective July 24, 2026 adds forced-labor-related duties across 60 investigated economies.
For importers, the trajectory is clear. Forced labor compliance is becoming a permanent, expanding feature of the import landscape. The cost of building a compliance program now is a fraction of the cost of a single detained shipment.
The Real Cost of Doing Nothing
A UFLPA detention is not a paperwork inconvenience. It is a business disruption that cascades through your entire operation. Goods held at the port generate storage charges that accumulate daily. Customers who do not receive product on time find alternative suppliers. Working capital locked in detained inventory cannot be deployed elsewhere. Legal costs for contesting a detention and preparing a response package run into tens of thousands of dollars. And the reputational damage of being publicly associated with forced labor enforcement actions can affect customer relationships, investor confidence, and brand value.
The importers who treat UFLPA compliance as a cost center they would rather avoid are the ones who pay the highest price when enforcement catches up to them. The importers who treat it as an operational discipline, with mapped supply chains, documented evidence, and a prepared response plan, are the ones whose shipments clear customs without incident.
In a trade environment where your goods are already navigating tariff stacking, classification complexity, and preference documentation requirements, adding forced labor compliance to the burden feels overwhelming. But it is not optional. And the importers who build it into their compliance infrastructure now, rather than scrambling after a detention notice arrives, are the ones who keep their goods moving and their customers served.
Frequently asked importer questions
What is a CBP Withhold Release Order (WRO)?
An enforcement action under 19 U.S.C. § 1307 that directs CBP to detain goods at every U.S. port of entry when information reasonably indicates they were made with forced labor. WROs name specific producers, factories, vessels, or regions and can apply anywhere in the world.
What is the difference between a WRO and the UFLPA?
A WRO targets named producers or regions globally; you respond by proving admissibility under 19 C.F.R. § 12.43 or exporting within three months after the date of importation. The UFLPA applies a rebuttable presumption to goods tied to Xinjiang or Entity List companies, which only clear and convincing evidence can overcome. Both run through CBP's Forced Labor Portal.
What should I do if my shipment is detained under a WRO?
Export, destroy, or contest. Contesting takes a 19 C.F.R. § 12.43 certificate of origin, a detailed importer statement, and complete supply-chain tracing — assembled within three months after the date of importation under 19 C.F.R. § 12.43.
Does U.S. forced-labor enforcement only apply to China?
No. The UFLPA is China-focused, but 19 U.S.C. § 1307 reaches goods from any country — the June 2026 Jordan garment WROs are the current proof.
This guide reflects UFLPA and Withhold Release Order enforcement practices and CBP requirements as of July 13, 2026. The UFLPA Entity List, enforcement priorities, and review procedures are updated regularly. Importers should monitor the CBP forced labor enforcement page, screen suppliers against the current Entity List, and consult with a licensed customs broker or trade counsel for guidance specific to their supply chains.
