Evaluating Chinese Factory Quality Tiers
1 resources tagged with "Supplier Evaluation"
Not all Chinese factories serve the same market. Export-grade OEM factories run AOI and ICT lines, hold ISO 9001, and produce to IPC-A-610 Class 2 or 3 — and price accordingly. Domestic-grade suppliers and trading companies sit below that, often cutting corners on component grade and testing to hit a domestic price point. Knowing which tier you're paying for is the difference between a clean shipment and a 5% defect rate.
Evaluating a supplier means matching the factory's actual capability to your quality target, not just its quoted price. We look at the production line, test equipment, certifications held, and whether the customer base is export or domestic — a factory that has never shipped to the EU rarely understands CE expectations.

FAQ
What separates an OEM factory from a trading company?
An OEM factory owns the production line and can show you the equipment, certifications, and staff; a trading company resells other factories' output and adds 5–15% margin. Ask to see the line and the business license scope.
What certifications signal a higher-tier factory?
ISO 9001 for quality management, plus product-specific marks like CE, FCC, or UL backed by real test reports. Build to IPC-A-610 Class 2 or 3 indicates an export-grade electronics line.
How do I verify a factory's quality level before ordering?
Run a factory audit covering equipment, process control, and past export records, then order a pre-production or golden sample to confirm the real output matches the claimed tier.
