1688 Supplier Verification Checklist
By Wechatscan Team · Aug 14, 2026 · 5 min read
Evaluate 1688 suppliers using business records, factory evidence, samples, specifications, contracts, quality control, and payment safeguards.
Supplier verification is a layered process. A business license confirms a registered entity, but not factory capability, export experience, product compliance, quality, capacity, or honesty. Combine document checks with samples, live evidence, written specifications, and independent inspection.
Verification layers
| Layer | Question answered | Evidence |
|---|---|---|
| Legal identity | Does the company exist and match the seller? | Business registration, legal name, address |
| Business role | Manufacturer, trader, or distributor? | Scope, facility evidence, staffing, equipment |
| Product capability | Can it make the specified product? | Samples, process, material and test records |
| Commercial reliability | Can it meet quantity, lead time, and terms? | Quotation, capacity, references, transaction history |
| Compliance | Can the product be legally sold in the destination? | Applicable tests, certificates, technical files |
| Quality control | How will defects be prevented and found? | Inspection plan, tolerances, approved sample |
Document checks
- Match legal name across license, invoice, bank beneficiary, and contract
- Check registered business scope and status
- Confirm the address and claimed facility
- Verify certificate issuer and scope
- Check whether test reports cover the exact product and model
- Translate key documents accurately
Factory evidence
Request a live video walkthrough or independent audit when risk justifies it. Ask to see relevant production steps, quality equipment, incoming materials, packaging, and current work. A polished showroom or stock image is not proof of manufacturing.
Sample process
- Send a written specification before requesting the sample.
- Label the approved sample and record measurements.
- Test safety, function, durability, color, materials, and packaging as relevant.
- Document every deviation.
- Confirm whether mass production will use the same materials and process.
- Define who keeps the golden sample.
Commercial terms
Use a written purchase agreement covering specification, quantity, price, tooling, lead time, inspection, defect remedy, intellectual property, packaging, labeling, delivery term, and dispute process. A chat promise is difficult to enforce.
Payment risk
- Verify beneficiary identity before paying
- Avoid unexplained last-minute bank changes
- Use milestones tied to evidence
- Retain leverage until inspection passes
- Understand platform protection limits
- Do not confuse low unit price with low total risk
Pre-shipment inspection
Define sampling level, defects, tests, and acceptance criteria before production. An inspection without a specification can only report observations, not determine whether the order meets requirements.
Compliance responsibility
A supplier certificate does not automatically make a product compliant in your destination. The importer or brand may carry legal responsibilities.
Score risks instead of using one label
A supplier can be strong in one area and weak in another. Use a risk register covering identity, technical capability, capacity, quality, compliance, payment, and logistics. Assign evidence and mitigation. Limited export experience may be manageable; inability to meet a safety specification may be unacceptable regardless of price.
- Score each risk category
- Assign evidence and mitigation
- Escalate safety and compliance gaps
- Update after samples and inspection
Frequently asked questions
Does a 1688 badge prove a seller is a factory?
No. Treat platform signals as inputs and verify the specific legal entity, facility, capability, and order.
Is a business license enough?
No. It confirms registration information, not production quality, capacity, compliance, or delivery.
When should I use an inspection company?
When order value, complexity, safety, custom production, or defect risk justifies independent evidence.
