Our apparel quality control process
Each custom order moves through eight inspection stages. Catching issues early — at fabric and cutting — costs far less than catching them at final inspection, so checks run continuously rather than only at the end.
▦
1. Fabric inspection
Check GSM, color, shrinkage and defects👘
2. Pattern approval
Verify patterns and construction✂
3. Cutting inspection
Confirm accurate cutting and sizing🧹
4. In-line check
Monitor stitching during production📏
5. Measurement
Verify garment specs and tolerances🔍
6. Final inspection
AQL-based pre-shipment check📦
7. Packing
Check packing and carton labeling🚚
8. Shipment
Release only after checks passDefect classification guide
View guide →Inspectors sort every fault into three tiers. The tier decides whether a shipment passes — a single critical defect usually fails a lot, while minor defects are allowed within set limits.
⚠ Critical defects
Faults that affect safety or function, or make the garment unusable.
Examples
- Broken or insecure stitching
- Holes and fabric tears
- Wrong fabric content
- Safety or labeling hazards
◯ Major defects
Faults a customer would likely notice and reject, but that are not unsafe.
Examples
- Open seams
- Incorrect measurements
- Print or embroidery errors
- Visible color mismatch
◎ Minor defects
Small faults that do not affect wear, fit, or function.
Examples
- Loose thread ends
- Slight shade variation
- Small surface spots

Compliance & certification standards Educational guide
View all standards →These are the standards buyers ask about most when sourcing apparel. This section explains what each one covers and why it matters — a reference for brands evaluating any manufacturer, not a claim of held certification. Eco Jersey’s certifications are in progress, and we’re happy to share current status on request.
Workwear & safety compliance Workwear vertical
View all standards →Safety apparel carries its own certification language. These are the European and US standards that govern high-visibility, protective, and flame-resistant workwear.

What is AQL and which level should I use? ▾
AQL (Acceptable Quality Limit) sets how many defective units a batch can contain and still pass a random inspection. Lower numbers are stricter: AQL 1.0 allows fewer defects than 2.5, which is stricter than 4.0. Most everyday apparel uses 2.5 for major defects and 4.0 for minor. Safety or premium garments often tighten to 1.0 or 1.5.
What is the difference between major and minor defects? ▾
A major defect is one a customer would likely notice and return — an open seam, wrong measurement, or print error. A minor defect is a small flaw that does not affect wear or function, like a loose thread or faint shade variation. Critical defects, which affect safety, sit above both and usually fail a shipment outright.
How often should inspections be done during production? ▾
Quality apparel manufacturing inspects continuously rather than only at the end: fabric on arrival, a first-piece check before bulk sewing, in-line checks during production, and a final random inspection before shipment. Early checks catch systemic issues while they are still cheap to fix.
What fabric tests are important before production? ▾
The core pre-production tests are GSM (weight), shrinkage, and color fastness, since these affect fit and appearance after washing. Performance fabrics add tear strength, abrasion, waterproofing, and breathability depending on the garment’s end use.
What compliance certifications should a manufacturer have? ▾
It depends on what you sell. OEKO-TEX Standard 100 covers textile safety, GRS covers recycled content, ISO 9001 covers quality systems, and BSCI, Sedex, or WRAP cover social and ethical compliance. Ask any manufacturer for current certificate status and validity dates rather than relying on logos alone.
