UFLPA Rebuttable Presumption: How to Overcome It at CBP

Key Points

• The Uyghur Forced Labor Prevention Act (Pub. L. 117-78, codified at 22 U.S.C. 6901 note) establishes a rebuttable presumption that any good mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region, or by an entity on the UFLPA Entity List, was made with forced labor and is therefore barred from U.S. entry under 19 U.S.C. 1307.
• The presumption applies regardless of the country of export or the final country of origin declared on entry documents, meaning goods processed through third countries remain covered if a Xinjiang nexus exists anywhere in the supply chain.
• To overcome the presumption, an importer must provide CBP with clear and convincing evidence that the goods were not made with forced labor, a standard that is deliberately demanding.
• CBP has published operational guidance identifying three categories of required proof: complete supply chain tracing, evidence of due diligence, and evidence that the goods comply with UFLPA standards.
• Goods detained under the UFLPA may be excluded or seized if the importer cannot meet the evidentiary standard; an importer that disagrees with a final determination may file a protest.

The UFLPA rebuttable presumption means that CBP must deny entry to any good with a Xinjiang nexus unless the importer proves, by clear and convincing evidence, that no forced labor was used anywhere in the supply chain. The burden of proof sits entirely on the importer, not on the government. An importer that cannot meet this burden will face exclusion of the shipment. The sections below explain the statutory framework, the evidence CBP expects, and the practical steps compliance teams need to take before a shipment reaches the port.

What the UFLPA Rebuttable Presumption Is and Why It Exists

Congress enacted the Uyghur Forced Labor Prevention Act (Pub. L. 117-78) and it was signed into law in December 2021. The statute is codified principally at 22 U.S.C. 6901 note. It builds on the longstanding prohibition on importing goods made with forced labor found at 19 U.S.C. 1307, which has been part of the Tariff Act of 1930 for decades.

Before the UFLPA, CBP had to affirmatively determine that specific goods were made with forced labor before it could detain them. The UFLPA reversed that burden entirely for goods connected to Xinjiang. Congress determined that the conditions of state-sponsored forced labor in the Xinjiang Uyghur Autonomous Region were so pervasive that a general presumption was warranted. The legislative finding embedded in the statute states that goods from the region should be presumed to be the product of forced labor unless CBP determines, after full consideration of all available evidence, that the presumption has been rebutted.

Scope: Which Goods and Entities Are Covered

The Xinjiang nexus

The presumption applies to any good mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region of China. "Wholly or in part" is critical: a finished product assembled outside Xinjiang can still be covered if any input, component, raw material, or intermediate good originated in Xinjiang. Common Xinjiang-linked commodity categories include cotton, polysilicon, tomatoes, and certain minerals, but the statute is not commodity-specific.

The UFLPA Entity List

The statute also covers goods produced by any entity named on the UFLPA Entity List, which is maintained by the Forced Labor Enforcement Task Force (FLETF) and administered by the Department of Homeland Security. An entity on the list need not be located in Xinjiang; what matters is that it has been identified as participating in forced labor practices covered by the statute. Importers should check the Entity List before engaging any supplier in the supply chain, not just Tier 1 suppliers.

Country of origin does not defeat the presumption

A declared country of origin other than China does not automatically remove a good from coverage. If a component or raw material from Xinjiang is incorporated into a finished product in Vietnam, Bangladesh, or any other country, the finished product retains a Xinjiang nexus and the presumption applies. Supply chain tracing must therefore reach back to raw material extraction, not just the country of final manufacture.

The Legal Standard: Clear and Convincing Evidence

The UFLPA sets the evidentiary bar at clear and convincing evidence. This is a deliberately high standard, sitting above the preponderance-of-the-evidence standard used in many civil proceedings. In practical terms, CBP reads it to mean that the evidence must produce a firm belief or conviction that the goods were not made with forced labor at any point in the supply chain. Ambiguous records, partial tracing, or supplier self-certifications alone will not satisfy this standard.

Congress also specified that CBP may only make a finding that the presumption is rebutted if it determines that the importer has fully complied with the guidance issued by CBP and the FLETF, and has provided all information necessary to make the determination. Partial or incomplete submissions are routinely treated as insufficient.

What CBP Requires to Overcome the Presumption

CBP has published detailed operational guidance explaining what it expects from importers seeking to rebut the presumption. That guidance, available on CBP's UFLPA page, identifies three categories of evidence:

1. Supply chain tracing

The importer must document every node in the supply chain from raw material extraction through to the finished imported good. This means records that identify each entity that processed, transformed, or transported the goods, the geographic location of each step, and the quantities and descriptions of inputs at each stage. Mill certificates, transaction records, shipping documents, and laboratory test results linking raw materials to finished goods are all relevant. CBP expects this documentation to be comprehensive, not selective.

2. Supply chain due diligence

CBP expects importers to demonstrate an ongoing program of due diligence on their supply chains, not a one-time audit triggered by a detention. Relevant evidence includes supplier contracts with forced-labor compliance representations, third-party audit reports from credible auditors, social compliance programs, training records, and remediation plans where issues have been identified. CBP's guidance draws on the FLETF's published guidance, which the importer should review directly on the DHS FLETF page.

3. Evidence of compliance with UFLPA standards

The importer must show that the specific shipment, and the supplier relationships behind it, actually comply with the standards the statute sets. This is where the first two categories converge: tracing without due diligence, or due diligence without tracing, is typically insufficient on its own. CBP officers reviewing a submission look for internal consistency across all three categories.

Timing and process

When a shipment is detained under the UFLPA, CBP issues a detention notice. The importer has a defined period to submit information in response. If CBP determines the presumption is not rebutted, the agency issues an exclusion order. The importer may then export the goods, abandon them, or pursue a protest. Importers should understand that the process moves on CBP's timeline, and incomplete submissions do not stop the clock.

Supply Chain Tracing and Documentation in Practice

Mapping before the shipment arrives

The most effective UFLPA compliance programs conduct supply chain mapping before goods are ordered, not after they are detained. A complete map identifies every supplier tier, every country where processing occurs, and every raw material source. Where Xinjiang-origin materials appear, the importer must either find an alternative source or be prepared to present the full rebuttal package at the border.

Document types CBP finds most useful

• Raw material sourcing certificates and origin affidavits from each supplier tier
• Purchase orders, invoices, and bills of lading linking each stage of production
• Laboratory analysis or isotope testing confirming geographic origin of cotton, polysilicon, or other traceable commodities
• Third-party audit reports that assess forced labor risk at each node
• Supplier-level payroll and worker recruitment records showing voluntary employment
• Internal compliance policies and evidence that they are actually implemented

Translation and authentication

CBP expects foreign-language documents to be accompanied by English translations. Importers submitting documents originating in China should be aware that the ability to obtain certain records, such as factory inspection reports or government-certified origin documents, may be limited by conditions on the ground, and CBP does not treat inaccessibility of records as an excuse for an incomplete submission.

Interaction with Other Forced Labor Trade Provisions

The UFLPA operates alongside, not instead of, the broader prohibition on forced-labor imports at 19 U.S.C. 1307. Goods not subject to the Xinjiang-specific presumption can still be detained and excluded under the general forced labor statute if CBP develops evidence that they were made with forced labor.

There are also Section 301 tariff provisions that interact with forced labor findings for goods from certain countries. Importers dealing with goods that transit multiple countries before U.S. entry should review how these provisions layer. See our article on the Section 301 forced labor transit exemption under HTS 9903.05.85 for coverage of when a transit exemption may apply.

Goods that enter a Foreign Trade Zone raise additional procedural questions about admission status and zone activity. For FTZ-specific procedures, see our article on CBP Form 214 and FTZ admission.

What Importers Should Do

• Map your entire supply chain to the raw material level for every product line, and identify any Xinjiang nexus or connection to an entity on the UFLPA Entity List before shipments are placed.
• Build and maintain a living due diligence program with documented supplier audits, contractual compliance requirements, and remediation procedures, so that evidence of compliance is available before CBP asks for it.
• Assemble a complete rebuttal package, covering supply chain tracing, due diligence evidence, and UFLPA compliance evidence, for any product line with a credible Xinjiang risk, and keep it updated with each new shipment cycle.
• If a shipment is detained, engage experienced customs counsel immediately, respond within the timeframes CBP specifies, and submit a complete, consistent evidentiary record rather than a partial submission that will not meet the clear-and-convincing standard.
