| 7. Financial Health Check | Review audited financials or credit reports (via Dun & Bradstreet China) | Assess solvency and investment capacity |
Step 3: Distinguish Factory vs. Trading Company
Many suppliers claim to be “manufacturers” but operate as intermediaries. Use the following indicators to differentiate:
| Indicator | Factory (Preferred) | Trading Company (Caution) |
|---|---|---|
| Business License Scope | Lists “manufacturing,” “production,” or “assembly” | Lists “trading,” “import/export,” or “distribution” |
| Facility Ownership | Owns land/building (check via property records) | Leases space or uses shared facilities |
| Production Equipment | On-site machinery (e.g., stamping, welding, battery lines) | No visible production assets during audit |
| Workforce Size | 200+ direct employees, including engineers and line workers | <50 employees, primarily sales/admin staff |
| Lead Time Control | Can quote precise production schedules | Defers to “our factory” or provides vague timelines |
| Pricing Structure | Breaks down material, labor, and overhead costs | Quotes flat FOB prices with limited cost transparency |
| R&D Department | Has in-house engineering team and lab facilities | No innovation history or product development capability |
✅ Best Practice: Require a factory walkthrough video with timestamped footage and employee ID verification.
Step 4: Red Flags to Avoid
| Red Flag | Risk | Mitigation Strategy |
|---|---|---|
| Unwillingness to allow on-site audit | High risk of misrepresentation | Require third-party inspection before PO |
| No direct export history | Likely reliant on intermediaries | Verify via customs data (Panjiva, ImportGenius) |
| Inconsistent branding or website quality | Poor operational standards | Audit digital presence and marketing materials |
| Pressure for large upfront payments (>30%) | Cash flow instability or fraud risk | Use LC or escrow; phase payments |
| Refusal to sign NDA or IP agreement | IP leakage risk | Engage legal counsel for IP protection clause |
| Claims of exclusivity with top OEMs without proof | Misleading marketing | Validate references independently |
| Multiple companies with same address/contact | Shell operations or fraud | Cross-check license numbers and management |
Final Recommendations
- Engage a Local Sourcing Agent with automotive expertise to conduct preliminary audits.
- Require a Pilot Order (10–20% of projected volume) before long-term commitment.
- Integrate Supplier into Compliance Portal for ongoing monitoring (e.g., EcoVadis, Sedex).
- Leverage Government Trade Missions (e.g., EU-China Trade Council) for introductions to verified OEMs.
Conclusion
Sourcing from China’s leading EV manufacturers offers strategic advantages in cost, scale, and innovation. However, rigorous verification is essential to avoid supply chain disruptions, quality failures, and IP risks. By applying this due diligence framework, procurement managers can confidently identify authentic factories, mitigate exposure, and build resilient partnerships in China’s dynamic EV ecosystem.
