Every batch of fabric, neoprene, silicone, elastic, and hardware is tested for thickness, tensile strength, and color fastness before production release
Non-conforming materials are rejected at the door

Key processes (silicone pad positioning on knee braces, stitching on grips) get 100% visual inspection

Stage 3 — Final Random Sampling (AQL)

AQL 2.5 per ANSI/ASQ Z1.4 (normal level II)
For a 5,000-piece order: QC team randomly samples 315 units
Acceptance criteria: critical defects = 0, major defects < 7, minor defects < 14 per 315-piece sample
Lots exceeding these limits are returned for 100% re-sorting before re-inspection

Stage 4 — Third-Party Inspection (Optional)

SGS, Bureau Veritas, TÜV, or Intertek inspectors welcome at buyer cost
Dedicated on-site inspection area with 48-hour advance sample preparation
