Raw Material Inspection
Fabric color difference, EVA density, outsole coefficient, and incoming material appearance are checked before production.
Quality Control
Every batch goes through 3-stage QC with AQL 2.5 standard.
Buyers need measurable quality controls before they trust a supplier. This page gives your sales team a concrete QC story before full inspection photos and third-party reports are ready.
In-Process Inspection
Production lines inspect size, weight, logo position, seam appearance, and packing status every 2 hours.
Final Shipment Inspection
Final random inspection follows AQL 2.5 Level II, with 5% batch sampling and 100% visual appearance review.
