Summary
A UFLPA Withhold Release Order (WRO) is a directive issued by U.S. Customs and Border Protection (CBP) under the Uyghur Forced Labor Prevention Act (UFLPA) that instructs CBP officers at all ports of entry to detain, exclude, or seize merchandise suspected of being produced wholly or in part with forced labor in the Xinjiang Uyghur Autonomous Region (XUAR) of China. As of June 2026, CBP has detained over $3.7 billion in goods under UFLPA enforcement, making it the most consequential trade compliance enforcement action of the decade for importers, customs brokers, and freight forwarders.

What the UFLPA Rebuttable Presumption Means
The UFLPA, signed into law on December 23, 2021, and fully effective June 21, 2022, establishes a rebuttable presumption that any goods mined, produced, or manufactured wholly or in part in the XUAR — or by entities on the UFLPA Entity List — were made with forced labor and are therefore prohibited from importation under Section 307 of the Tariff Act of 1930.
> "The rebuttable presumption applies to goods mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region of China, or produced by entities on the UFLPA Entity List." — U.S. Customs and Border Protection, UFLPA Operational Guidance
The critical word is rebuttable. Unlike a standard detention, an importer has the legal right to challenge the presumption by submitting clear and convincing evidence to CBP that the goods were not produced with forced labor. This is the foundation of the UFLPA compliance defense strategy.

How a UFLPA Withhold Release Order Works
When CBP issues a WRO under UFLPA, the following sequence occurs at the port of entry:
| Stage | Action | Timeframe | |-------|--------|-----------| | 1. Detention Notice | CBP issues a CF-28 (Request for Information) or CF-29 (Notice of Action) to the importer of record | Day 1–3 of arrival | | 2. 30-Day Response Window | Importer has 30 days to submit rebuttal evidence (extendable by CBP) | Days 1–30 | | 3. CBP Review | CBP reviews submitted documentation against UFLPA standards | 30–90 days | | 4. Admissibility Decision | CBP issues one of three outcomes: admitted, excluded, or seized | Variable | | 5. Exclusion/Seizure | If evidence is insufficient, goods are excluded or seized; importer may appeal to CBP Commissioner | Post-decision |
The WRO is not shipment-specific. Once CBP targets a commodity, supplier, or supply chain node, all future shipments from that source are subject to the same scrutiny until the importer demonstrates systemic compliance.

What Triggers a UFLPA Detention
CBP uses risk-based targeting to identify shipments for UFLPA review. The primary triggers are:
