Socks Quality Standards & Compliance: AQL, OEKO-TEX & What Retailers Require

Quality is not just "it looks fine." For B2B and retail socks, quality is a set of measurable standards—and a set of certificates that open (or close) doors. Here is what matters.

1. AQL: The Inspection Language

Acceptable Quality Limit defines how many defects are tolerated in a random sample.

• AQL 2.5 (general): standard for most retail socks
• AQL 1.5 (strict): premium and medical segments
• AQL 4.0 (relaxed): promo/novelty, non-critical use

Inspection covers major defects (holes, wrong size) and minor defects (loose thread, slight shade variance).

2. Material Safety: OEKO-TEX 100

OEKO-TEX 100 certifies the finished sock is free from harmful substances. It is increasingly a hard requirement for EU and German retailers.

3. Social & Environmental Compliance

Major retailers audit the factory, not just the product:

• BSCI / WRAP / SLCP: labor and workplace standards
• GRS: recycled content traceability
• Walmart FCCA / Costco: specific factory audit protocols

4. Our 6-Stage QC in Practice

1. Yarn incoming inspection
2. In-line knitting inspection
3. Linking / toe inspection
4. Boarding / shape inspection
5. Final AQL random inspection
6. Pre-shipment inspection

Skipping in-line inspection to save a day is the #1 cause of bulk-order quality surprises. We never skip it.

5. What to Request From Any Supplier

• Valid certificate copies (not expired)
• Third-party AQL inspection reports
• A clear defective-pair replacement policy
