Quality Control

Quality is controlled at four points — not one final inspection. IQC before storage, IPQC on the line, FQC before packing, OQC before shipment. Every order ships against AQL 2.5 / 4.0.

01Before storage

Incoming Quality Control

IQC

100% of incoming raw materials — fabrics, metals, leathers, zips and dyes — are checked for color accuracy, thickness and safety before they enter storage.

  • Color matched to the approved swatch under D65 light
  • Thickness, weight and coating verified against specification
02On the line

In-Process Quality Control

IPQC

Continuous checks during cutting, stitching and assembly catch defects while they can still be corrected — not after the whole order is finished.

  • First-article approval at every production start
  • Roving inspection across cutting, stitching and assembly
03Before packing

Final Quality Control

FQC

100% piece-by-piece inspection of every finished accessory against the approved tech pack and pre-production sample.

  • Stitching accuracy, structural integrity and hardware function
  • Cosmetic defects checked under inspection lighting
04Before shipment

Out-going Quality Control

OQC

Pre-shipment audit to AQL 2.5 / 4.0, including carton drop tests, moisture sealing and barcode verification.

  • AQL sampling: critical 0, major 2.5, minor 4.0
  • Drop test, shipping marks and barcode check before sealing
