Factory Verification & Due Diligence in Vietnam
Before placing an order, buyers should verify that a supplier is legitimate, capable, and suitable for the product they intend to manufacture. Factory verification reduces sourcing risk by confirming whether the supplier can actually produce, control quality, and export reliably.
Key principle: A professional website, attractive samples, or low quotation does not guarantee manufacturing capability. Verification should happen before deposits, tooling payments, or production approval.
Factory Verification Checklist
| Verification Area | What to Check | Why It Matters |
|---|---|---|
| Company Identity | Registration, legal name, address | Confirms supplier legitimacy |
| Factory Site | Production location and facility size | Confirms where goods are made |
| Equipment | Machines, tools, production lines | Confirms technical capability |
| Workforce | Staff size, skills, production teams | Shows capacity and scalability |
| Quality Control | Inspection process and defect tracking | Reduces quality risk |
| Export Records | Export markets and documentation | Shows international readiness |
Documents to Request
- Business registration certificate
- Factory profile
- Export documentation examples
- Quality control procedures
- Relevant certifications
- Testing reports where applicable
Red Flags During Verification
- Refusal to share basic company documents
- Different company name on invoices
- No clear factory address
- Unwillingness to allow inspection
- Poor knowledge of product details
- Evidence of undisclosed subcontracting
Best practice: Verify shortlisted suppliers before sample approval or deposit payment. Early due diligence is cheaper than solving problems after manufacturing has started.
