Confirm the specification first
Quality control starts before production. The approved specification should identify the exact model, electrical rating, materials, appearance requirements, accessories, packaging and any required documentation. This creates a measurable basis for inspection.
Check production and finished goods
Checks may cover assembly, appearance, function and packaging consistency. For completed goods, inspection can include quantity, workmanship, labeling, basic functional checks and carton condition according to the agreed inspection plan.
Verify documents by model and market
Certificates and test documents are product-specific. Buyers should confirm that each document matches the exact model and destination-market requirements rather than assuming one document covers an entire category.
