UFLPA Supply Chain Due Diligence

Overview

UFLPA supply chain due diligence is the process of identifying, preventing, and documenting forced-labor risks in goods destined for the United States under the Uyghur Forced Labor Prevention Act (UFLPA), Public Law 117-78. The law establishes a rebuttable presumption that 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 prohibited from U.S. importation under Section 307 of the Tariff Act of 1930.

The presumption applies to covered inputs as well as finished goods: processing or assembly in another country does not automatically remove a product from its scope. U.S. Customs and Border Protection (CBP) enforces the law at the border. The Entity List and the broader enforcement strategy are maintained by the Forced Labor Enforcement Task Force (FLETF), which the Department of Homeland Security chairs. Due diligence therefore combines supplier investigation, traceability, labor-risk assessment, and preparation of evidence for customs review. It is not a statutory certification and does not by itself guarantee that merchandise will be released.

Etymology and Origins

“UFLPA” is the acronym for the Uyghur Forced Labor Prevention Act, enacted as Public Law 117-78. “Supply chain due diligence” refers more broadly to an ongoing process through which businesses identify, prevent, mitigate, and account for adverse impacts connected to their operations and relationships.

The combined phrase describes the application of that broader practice to the act; it is not a distinct statutory certification or a guarantee of admissibility. Its practical meaning draws on both the act’s import restrictions and the risk-based framework in the OECD Due Diligence Guidance for Responsible Business Conduct. A first documented use of the combined phrase has not been established here.

Historical Development

• 1930: Section 307 of the Tariff Act of 1930 established the U.S. prohibition on importing goods made wholly or in part with forced labor. It provides the legal foundation on which UFLPA enforcement builds.
• 2016: On February 24, 2016, President Barack Obama signed the Trade Facilitation and Trade Enforcement Act of 2015 (Public Law 114-125). That law repealed the consumptive-demand exception to Section 307, which had permitted certain imports despite the forced-labor prohibition when domestic production was said not to meet U.S. demand.
• 2018: The OECD published its Due Diligence Guidance for Responsible Business Conduct on 31 May 2018, setting out a general, risk-based approach applicable to labor and other impacts.
• 2021–2022: Congress passed the UFLPA, and President Joe Biden signed it on December 23, 2021. Its rebuttable presumption took effect on June 21, 2022, 180 days after enactment, as the statute required. The law also required a government strategy and an entity list. FLETF published its initial UFLPA Strategy on June 17, 2022, and identified apparel, cotton and cotton products, silica-based products (including polysilicon), and tomatoes and downstream products as initial high-priority sectors for enforcement.
• 2020s: Importers use digital supplier maps, transaction records, and lot identifiers alongside other evidence to support the traceability described in CBP’s importer guidance. Digital outputs remain dependent on the accuracy and completeness of underlying records. CBP publishes enforcement statistics on shipments examined under the UFLPA; those figures change over time and should be dated when cited.

Core Concepts

Presumption and scope

Under the UFLPA’s statutory framework, goods within the presumption are treated as prohibited unless the importer obtains an exception. Relevant facts include where materials were mined, produced, or manufactured and whether an entity involved appears on the Entity List published through the FLETF. Risks are not limited to a finished product’s declared country of origin.

A claim that goods are outside the law’s scope is different from a request for an exception to the presumption. To obtain an exception, an importer must, among other requirements, fully comply with applicable guidance and respond completely and substantively to CBP’s information requests; CBP must also determine, by clear and convincing evidence, that the goods were not mined, produced, or manufactured wholly or in part by forced labor. A supplier declaration alone should not be treated as sufficient proof. The statutory exception standard is set out in Public Law 117-78 and explained in CBP’s operational guidance.

Traceability and evidence

CBP’s importer guidance describes the importance of supply-chain mapping, due-diligence and supply-chain management measures, and evidence tracing merchandise and its components to the raw materials. Useful records can include purchase orders, invoices, production orders, bills of materials, transport documents, payment records, and records identifying raw-material sources.

The objective is to connect evidence across transactions and transformations. For example, a cotton apparel importer may need to link a finished garment to its fabric mill, yarn spinner, cotton processor, and raw-cotton source—not merely to the garment factory. Quantity reconciliation can reveal gaps where purchased input volumes do not plausibly support reported output, allowing for documented yields and inventory movements. Cotton, apparel, polysilicon, and tomato supply chains have been identified as high-priority sectors, but the presumption is not limited to those sectors.

Illustrative reconciliation: If a mill identifies 1,000 kg of incoming yarn as the source for a shipment, an importer can compare that quantity with production records, opening and closing stock, waste, and the fabric output attributed to the yarn. An unexplained excess or a missing lot link should trigger investigation rather than an assumption that the shipment is traceable. This follows the document-linking approach in CBP’s guidance; it is not a prescribed CBP calculation or a real case study.

Due Diligence Process

1. Map suppliers and materials. Identify direct suppliers and, where feasible, upstream processors, traders, and raw-material sources. Record facility locations, ownership, production steps, and shipment routes.
2. Screen and prioritize risks. Check relevant parties against the current UFLPA Entity List and government strategy. Prioritize products with opaque upstream sourcing, high-risk inputs, inconsistent records, or supplier links requiring further investigation. Screening a supplier’s name alone is not a substitute for tracing goods.
3. Obtain and reconcile records. Request transaction and production documents for the actual goods and relevant inputs. Compare dates, quantities, units of measure, facility capacity, and custody transfers; investigate missing links and discrepancies.
4. Assess labor risks. Examine recruitment, worker payment, freedom of movement, and other indicators where credible information is available. The ILO’s forced-labor indicators provide a framework for identifying warning signs; an indicator is a prompt for investigation, not automatically a conclusive legal finding under U.S. import law. The OECD guidance recommends addressing adverse impacts and tracking the effectiveness of responses, rather than relying solely on supplier promises.
5. Prevent or mitigate exposure. Escalate unresolved risks, require corrective action where appropriate, and consider suspending purchases or changing sources when reliable evidence cannot be obtained. Engage legal and compliance specialists on consequential decisions.
6. Maintain an evidence package. Keep records organized by product, shipment, supplier, and production lot so the importer can respond promptly and consistently to a CBP inquiry. Refresh mapping and screening when suppliers, ownership, routes, or government listings change.

Technology and Operational Controls

Purchase-order and inventory systems can help maintain transaction links. For example, purchase order records can associate receipts with vendors and ordered quantities, while lot and expiration-date records can help distinguish batches after receipt. These are operational records, not proof that upstream goods were free of forced labor and not a substitute for the evidence described by CBP.

A practical control is to preserve identifiers through receiving, storage, transformation, and shipment and connect them to supplier documents held elsewhere. Barcode workflows can reduce manual identification errors when labels and master data are accurate. Importers must still obtain credible upstream records, verify their consistency, and retain the broader documentation described in CBP’s guidance.

Enforcement and Limitations

CBP may detain, exclude, or seize merchandise in connection with UFLPA enforcement. An importer should identify the shipment and affected inputs, preserve records, determine whether it is presenting an applicability (outside-scope) claim or seeking an exception to the presumption, and follow the instructions and applicable deadlines in CBP’s notice. The agency’s UFLPA resource page provides guidance and enforcement information, and its statistics page reports shipment outcomes that should be read with their publication date.

Significant limitations include opaque subcontracting, commingled raw materials, inconsistent supplier records, and difficulty independently verifying labor conditions. An audit, certificate, blockchain entry, or warehouse record cannot by itself establish the origin and labor conditions of every input. Companies should document verification gaps and decisions, use multiple sources of evidence, and update their controls in line with the government’s UFLPA strategy and current legal guidance.
