How to Create a QC Checklist That Your Chinese Factory Will Respect

Factory QC culture varies significantly across China. Export-oriented factories in Guangdong and Zhejiang typically have robust QC systems. Domestic-focused factories may have minimal QC. The most reliable indicator is whether the factory has dedicated QC staff separate from production staff. A factory where production workers also do QC inspection is a red flag. Independence of the QC function from production pressure is essential.

Pre-Production Inspection (PPI) is the most cost-effective quality step. It happens when 10-15% of production is complete. At this point, any issues can be corrected before they affect the entire batch. PPI typically checks: first article dimensions against spec, material verification, color/ finish approval, packaging design confirmation, and production line setup. The cost is typically $300-400 and prevents thousands in potential rework.
