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

LayerQuestion answeredEvidence
Legal identityDoes the company exist and match the seller?Business registration, legal name, address
Business roleManufacturer, trader, or distributor?Scope, facility evidence, staffing, equipment
Product capabilityCan it make the specified product?Samples, process, material and test records
Commercial reliabilityCan it meet quantity, lead time, and terms?Quotation, capacity, references, transaction history
ComplianceCan the product be legally sold in the destination?Applicable tests, certificates, technical files
Quality controlHow 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

  1. Send a written specification before requesting the sample.
  2. Label the approved sample and record measurements.
  3. Test safety, function, durability, color, materials, and packaging as relevant.
  4. Document every deviation.
  5. Confirm whether mass production will use the same materials and process.
  6. 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.
