Four layers of production control.
In-process
Assembly appearance, function, pairing, controls, charging, and acoustic checks sampled during production.
Final
Finished goods sampled for cosmetics, function, accessories, labels, packaging, and carton marks.
Pre-shipment
Inspection record and photos reviewed before shipment release.
Buyer protection
Define acceptance before production.
Quality is easier to manage when requirements are measurable. The approved sample, BOM, artwork files, color reference, packaging specification, test method, AQL level, and defect definitions should be agreed before the production deposit.
For higher-risk or first-time orders, third-party inspection can be added before final payment or shipment release.
