UFLPA Traceability

US Customs and Border Protection detained over $2 billion worth of goods in UFLPA enforcement actions during the first two years of the Act's operation, with textiles, solar components, and electronics accounting for the majority of seizures. The Uyghur Forced Labor Prevention Act establishes a rebuttable presumption: any goods mined, produced, or manufactured wholly or in part in China's Xinjiang Uyghur Autonomous Region are presumed made with forced labour and barred from US entry. The burden of proof falls entirely on the importer — you must demonstrate "clear and convincing evidence" of a forced-labour-free supply chain, or your shipment stays in detention.

CBP gives importers approximately 30 days from a detention notice to submit an admissibility package. That package must include complete supply chain mapping from raw materials through finished goods, purchase orders and invoices for every tier, production records showing worker recruitment and payment evidence, and independent audit reports. Most companies cannot assemble this evidence in 30 days from scratch — the ones that get shipments released are those with documentation already organised before detention occurs.

Sustalium's approach is proactive documentation rather than reactive crisis management. Each product line with potential Xinjiang supply chain exposure gets a traceability record that maps every supplier tier, links to due diligence questionnaires and audit reports, and stores chain-of-custody evidence by material type. If CBP issues a detention notice, your admissibility package is an export away — not a scramble across email archives and supplier portals. For companies also subject to the UK Modern Slavery Act or Bill S-211, the same underlying supply chain evidence serves multiple forced-labour compliance frameworks.
