Chain-of-custody evidence is the core of the SIMS method, the same lot-level tracing that evidences diversion evidences origin.
Forced-labor enforcement presumes goods with exposure are inadmissible unless the importer proves otherwise, and the proof is a chain-of-custody problem. Supplier attestations alone do not release a detained shipment; documentary evidence of the actual chain does.
What SIMS does here
Multi-tier supply chain mapping
Origin tracing from raw material through finished goods, documented to the standard the agency applies.
Due diligence controls
Forced-labor due diligence built into business-partner screening and site assessment, not bolted on afterwards.
Custody evidence package
Purchase orders, production records and transport documents tied lot by lot, the records that answer a detention.
Detention response
Admissibility package assembled and argued by trade-compliance specialists, with counsel where the matter warrants it.
Frequently asked questions
Are supplier certifications enough?
No. The standard is documentary evidence of the actual chain, tied lot by lot. Attestations without custody evidence do not release detained goods.
Certification, validation, refund and clearance are agency decisions and are never guaranteed. Recovery amounts and timelines depend on the facts.
