Inspection parameters are established upfront for exterior defects (scratches, burrs, foreign particles), piece counts, SKU matching, color consistency, print fidelity, and compliance labels. Protocols—100% full inspection or statistical sampling based on ISO/AQL standards—are agreed according to product value and volume.
Inbound goods are strictly cross-checked against approved purchase order specifications and golden samples. Precise dimensional tolerances, gross weights, power/functional operations, and mechanical component fit are audited according to customized product checklists.
Every defect is documented by classification (Critical, Major, Minor), defect count, and high-resolution photo evidence. Under pre-agreed contract terms, we enforce free factory rework, non-conforming unit replacement, shortage replenishment, and mandatory re-inspection locally in China.
Vacuum leak testing, long-term durability cycling, chemical hazard analysis, and mandatory statutory testing through accredited laboratories (SGS, TÜV, RoHS, PSE) are arranged on demand. We clearly segregate routine visual inspections from destructive lab trials, quoting scopes and costs upfront.
For larger volume production, statistical sampling based on international AQL standards can be agreed to balance cost efficiency and strict quality control. The following illustrates an agreed sampling protocol for screen-printed cosmetic glass bottles:
Sampling baseline: Randomly draw and inspect 50 units per master carton of 500 bottles.
If any defect threshold is reached, the affected carton/lot is rejected, and GAMU immediately coordinates factory return, sorting, or rework. All findings are logged in an official inspection report bearing our corporate seal. Actual sampling ratios and acceptance criteria are tailored to each product category.
