Supply chain
China-based delivery: building an evidence chain from specification to handover
In cross-border projects, manufacturing is not always the weakest point. Information changes hands repeatedly between the owner, designer, factory, inspector, logistics provider and site team. An evidence chain gives each transfer a version, an accountable owner and an acceptance criterion.

Start with a requirements matrix
Give every function, environmental condition, interface, regulatory requirement and acceptance measure a unique identifier. Supplier deviations, clarifications and alternatives should return to that identifier rather than remain only in messages.
Match supplier verification to project risk
- Consistency of contracting and manufacturing entities
- Actual manufacturing location and critical processes
- Document and sample evidence for comparable products
- Subcontracted processes and critical material sources
- Quality records, capacity window and change control
Create four release gates
- Design freeze: drawings, BOM, interfaces and deviation list
- Production release: critical materials, first article and process inspection
- Shipment release: FAT, packing, marking and packing list
- Site handover: arrival inspection, installation, commissioning, training and spares
Every substitution must be traceable
Shortage, obsolescence or transport constraints may trigger a substitution. Record the reason, technical effect, compliance effect, delivery effect and approver. An unapproved “equivalent” should not enter shipment status.

Use boundary
Supplier verification and inspection reduce information risk; they do not guarantee any entity, product or delivery outcome.
