How should a buyer compare China suppliers?
Compare suppliers with the same evidence fields: legal identity, ownership, manufacturing role, product scope, location, quotation assumptions, quality controls, compliance evidence, payment beneficiary and communication record. Separate supplier statements from independently reviewed records, and record every unresolved gap before shortlisting or paying a deposit. Start with China supplier research.
What should be verified before paying a supplier deposit?
Before a deposit, verify the contracting entity, payment beneficiary, business registration, operating address, product capability, quotation scope, tooling ownership, quality requirements and agreed commercial milestones. A matching company name alone does not prove production capability or reduce performance risk. Use the supplier verification framework.
When is factory verification useful?
Factory verification is useful when the manufacturing location, production capability or process control materially affects the buyer decision. It is especially relevant before custom tooling, high-value deposits, regulated products, new production processes or orders where an unverified subcontractor would create significant delivery or quality exposure. Review factory verification scope.
How is factory verification different from product inspection?
Factory verification examines the supplier and production environment: identity, location, equipment, people, processes and claimed capability. Product inspection examines a defined batch against specifications and sampling criteria. One does not replace the other; they answer different buyer questions at different decision stages. See quality control.
What should a China sourcing RFQ include?
A useful RFQ defines the product, material, dimensions, tolerances, quantity, packaging, destination market, compliance requirements, inspection criteria, Incoterm, target schedule and required quotation breakdown. Consistent assumptions make supplier responses easier to compare and expose exclusions before negotiation. Use the structured RFQ request.
When should product inspection happen?
Inspection timing should match the risk. Pre-production checks confirm inputs and readiness, during-production inspection identifies process problems while correction is still possible, and pre-shipment inspection evaluates finished goods before release. The appropriate combination depends on product complexity, supplier history and the cost of late discovery.
What evidence supports shipment release?
Shipment release should rely on the agreed inspection result, defect and rework status, quantity, packaging, labeling, compliance documents, commercial documents and buyer-approved exceptions. A passed inspection does not automatically resolve document, payment, logistics or regulatory conditions outside the inspection scope. Review inspection report review.
How should a buyer choose a China manufacturing region?
Choose a manufacturing region by category fit rather than city reputation alone. Review supplier density, component access, process capability, labor and tooling availability, logistics, export experience and the feasibility of field verification. The best region depends on the product and destination-market requirements. Explore the China manufacturing map.
