| 7 | Analyze Supply Chain & Raw Material Sourcing | Assess supply chain resilience | Require transparency on component suppliers (e.g., sensors, compressors). Ensure dual sourcing for critical parts. |
How to Distinguish Between a Trading Company and a Factory
| Indicator | Factory | Trading Company |
|---|---|---|
| Business License | Lists “manufacturing” as primary activity | Lists “trading”, “import/export”, or “distribution” |
| Facility Ownership | Owns or leases production plant (evidenced in audit) | No production floor; uses agent factories |
| Pricing Structure | Lower MOQs, direct cost transparency | Higher margins, vague cost breakdowns |
| Production Lead Time | Direct control over scheduling | Dependent on third-party factories; longer lead times |
| Customization Capability | Offers OEM/ODM with engineering support | Limited to catalog-based offerings |
| Workforce | Employs engineers, technicians, QC staff | Sales and logistics-focused team |
| Equipment On-Site | CNC machines, assembly lines, testing labs | Office space only; no machinery |
Pro Tip: Ask to speak with the Production Manager or Plant Supervisor during audits. Trading companies often cannot produce technical staff on demand.
Red Flags to Avoid in 2026
| Red Flag | Risk Implication | Mitigation Strategy |
|---|---|---|
| No verifiable factory address or refusal to allow audits | High risk of trading company posing as a factory | Mandate third-party audit before PO placement |
| Inconsistent product specifications across quotes | Lack of technical control; possible reselling | Require signed technical drawings and BOMs |
| Unrealistically low pricing | Substandard materials, corner-cutting | Benchmark against 3–5 verified suppliers |
