Start with the general import prohibition
Section 307 of the Tariff Act of 1930, codified at 19 U.S.C. § 1307, prohibits US imports of goods mined, produced or manufactured wholly or partly in any foreign country using the labour categories specified in that provision, including forced labour. Its scope is broader than Xinjiang or the UFLPA Entity List.
UFLPA adds a rebuttable presumption for specified Xinjiang and listed-entity links. It is not the complete US forced-labour enforcement regime. Read the UFLPA guide alongside the general prohibition.
Keep enforcement mechanisms distinct
CBP uses Withhold Release Orders (WROs) and Findings in Section 307 enforcement. CBP describes a WRO as based on evidence that reasonably, but not conclusively, indicates covered goods are made with prohibited labour; a Finding follows a determination supported by the evidence. See the linked CBP definitions.
A shipment review needs the actual legal basis and applicable procedure. Do not treat a WRO, a Finding and a UFLPA detention as interchangeable labels or assume they share the same response pathway.
Map the shipment beyond the exporter
Start with the imported shipment and its goods, lot references and quantities. Trace backwards through assembly, processing and raw-material sources. Identify both the seller and the physical facility at each step. An exporter in one country may be selling a product made with inputs produced elsewhere.
Ask which purchase, production and transfer records connect each input to the goods being imported. Material origin and chain of custody explains why a last shipping location is only one part of that history. Preserve gaps instead of filling them with assumptions about country of origin.
Organise responses around the specific question
For an actual enforcement action, record the notice, shipment references, responsible reviewer and requested information. Have the importer and relevant specialists determine the appropriate response pathway and current procedural requirements. A generic supplier questionnaire is not a response to every possible customs concern.
Operationally, build a document index keyed to the shipment and supply-chain stages. Show what each record supports, which facility and period it covers, and where quantities or identities do not reconcile. Retain evidence supporting the conclusion as well as evidence that challenges it.
Use traceability as a preparation tool
Run a mock retrieval exercise before a shipment is dispatched: can the team reproduce the material-to-shipment chain using records it can actually access? Include a broker-supplied input, an outsourced processing step and a supplier name change. Escalate unresolved links to an assigned owner.
The exercise measures the quality of the records, not legal admissibility. Maintain separate conclusions for the EU Forced Labour Regulation and US import enforcement, even when they reference the same facilities. Update legal references and official list checks as part of the review rather than relying indefinitely on a past screen.
