How to Choose a Reliable Supplier in China
When comparing suppliers, buyers should evaluate five factors before placing a first order: factory ownership, documentation completeness, testing capability, delivery reliability and communication. A genuine factory supplier can show production lines, heat number traceability and in-house testing; a trading company can only relay documents.
- Verify factory ownership and production capacity
- Request the MTC and test reports from recent shipments
- Confirm the governing standard and grade for every size
- Agree on packing, marking and documentation requirements in writing
- Start with a sample or small order to verify product and service quality
