Short answer: a supplier verification checks identity and basic legitimacy; a factory audit evaluates systems and capability; a product inspection checks a specific order. A clean factory audit does not prove that your shipment passes, and a passing shipment does not prove that the supplier is financially or legally low-risk.
Side-by-Side Comparison
| Check | Main question | Best timing |
|---|---|---|
| Supplier verification | Is this the registered company and operating location it claims to be? | Before deposit or sensitive document exchange |
| Factory audit | Can its people, equipment and systems reliably make this product? | Before approving a strategic or complex supplier |
| Product inspection | Does this production lot meet the buyer's written specification? | During production or before final payment/shipment |
| Container loading check | Were the approved cartons counted, protected and loaded correctly? | At loading |
What a Supplier Verification Should Evidence
- Registered Chinese company name, unified social credit code and status.
- Address and whether the visited operating site matches the claimed business.
- Bank-account beneficiary and contract entity consistency.
- Product-category relevance and basic export/marketplace claims.
- Photos or video tied to the visit without claiming more than they show.
A verification is a screening step. It cannot guarantee future performance, ownership of every machine shown, solvency or product compliance without additional evidence.
What a Factory Audit Goes Deeper On
- Production flow, key equipment, capacity evidence and subcontracting.
- Incoming material controls, traceability and nonconforming product handling.
- Calibration, work instructions, training and quality records.
- Corrective action, complaint handling and change control.
- Social, environmental or customer-specific modules when agreed.
The audit scope must be written. A one-hour visit and a multi-module quality-system audit should not be sold as the same service.
What Product Inspection Adds
Inspection tests a defined lot against an approved sample, specification, purchase order and defect rules. When sampling is used, the buyer should approve the sampling plan, inspection level and AQL before the visit. ISO published ISO 2859-1:2026 as the current edition for AQL-indexed inspection by attributes; using the name “AQL” alone does not define your defect limits or test protocol.
Which One Do You Need?
- New low-risk standard product: verification plus pre-shipment inspection.
- Custom tooling or regulated product: deeper audit, sample approval and staged inspections.
- Existing supplier with a quality problem: process-focused audit plus inspection of corrected production.
- Marketplace seller or trading company uncertainty: verification first; determine who actually manufactures.
- Large loading risk: pre-shipment inspection followed by container loading supervision.
Questions to Put in the Written Scope
- Which legal entity and physical site are being checked?
- Which product, order and specification are in scope?
- Is subcontracting allowed and how will it be verified?
- What photos, records and tests must appear in the report?
- Who defines critical, major and minor defects?
- Does a fail trigger rework, reinspection or buyer review?
Choose the Check Before Paying a Deposit
Send the supplier name, product, order stage and the decision you need to make. We will propose a written evidence scope instead of a vague “factory check.”
