How to Interpret an Inspection Report Like a Professional

Inspection sampling should be genuinely random. A common factory trick is preparing perfect units on top of pallets while concealing defects in the middle. Professional inspectors break down stacks, sample from inner cartons, and mix their own selection rather than using pre-staged samples. Instruct your QC team to be unpredictable in their sampling pattern. Random sampling is only valuable if it's actually random.

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.
