OEM/ODM Quality Control Checklist: What to Verify Before Bulk Production
Quality issues in sportswear are usually cheaper to prevent than to fix. Use this checklist before and during bulk production to protect your brand and margins.
1. Pre-Production Checks
- Approved sample: confirm the sample exactly matches your approved version.
- Tech pack: patterns, measurements, trims and construction details in writing.
- Fabric test: weight (GSM), composition, shrinkage, color fastness.
- Color standard: approve lab dips or color swatches under consistent lighting.
2. In-Production Checks
| Check Point | What to Verify |
|---|---|
| Cutting | Fabric direction, pattern matching, correct layering |
| Sewing | Stitch density, seam strength, alignment, no loose threads |
| Printing/embroidery | Placement, color accuracy, adhesion, no bleeding |
| Sizing | Measurement against size chart on random samples |
| Accessories | Zippers, drawcords, snaps and labels function correctly |
3. Pre-Shipment Inspection (PSI)
- Random sampling by AQL standard (typically 2.5).
- Check quantity, packing, carton marks and mixed-size assortment.
- Verify labels and care instructions match target-market regulations.
4. Documentation to Collect
Keep fabric test reports, inspection photos, PSI report and shipping documents. These protect you in disputes and help with market compliance.
FAQ
Do I need to hire a third-party inspector?
Not always. A factory with strong internal QC can provide reports and photos, but third-party inspection adds independent assurance for large orders.
What is the AQL standard for sportswear?
General merchandise typically uses AQL 2.5 for major defects and 4.0 for minor defects, agreed before production.
Can the factory fix issues found during production?
A professional factory corrects issues before shipment and documents the correction. Choose a partner with a clear correction process.
