AQL 2.5 Inspection for Bags: What It Means for Your Order

When you order 5,000 bags you cannot inspect every stitch yourself. AQL is the industry-standard way to define and verify quality — and knowing how it works makes you a better buyer.

What AQL means

AQL stands for Acceptable Quality Limit. It is a statistical sampling method: instead of checking every piece, a defined number of pieces is inspected at random, and the order is accepted or rejected based on how many defects are found. The number — 2.5 — is the defect rate considered acceptable for "major" defects.

So AQL 2.5 does not mean "2.5% of bags may be defective and get shipped". It means: if the inspection finds more major defects than the plan allows, the batch fails inspection and must be reworked or replaced.

Major, minor and critical defects

How our QC process works

1. Incoming material check — fabric weight, colour and width verified against the order.
2. First article approval — the first pieces off the line are compared with the approved sample.
3. In-line inspection — operators check stitching and print as production runs.
4. 100% inspection of finished bags — every piece is checked and trimmed, which is stricter than AQL sampling alone.
5. Final AQL 2.5 audit — a random sample from the finished batch is audited to confirm the batch passes.
6. Photo report — we send photographs of your goods, packing and cartons before shipment.

What we check on every bag

• Size within ±1 cm of spec
• Fabric weight and colour against the approved sample
• Stitch density and thread tension; no skipped stitches or loose ends
• Handle attachment strength and bar-tack / X-box reinforcement
• Print position, size and colour accuracy
• Zipper, drawstring or button function where applicable
• Cleanliness, odour and no oil marks
• Carton count, packing method and shipping marks

Can you use a third-party inspector?

Yes, and for large first orders we recommend it. SGS, Bureau Veritas, Intertek and QIMA all inspect factories in China. You book and pay them directly; we schedule the inspection at the factory when the goods are ready. Most inspections take one day and cost a few hundred dollars — insurance that pays for itself on a container order.

What the inspection report tells you

A report typically contains: the inspection date, the number of pieces inspected, the defects found by class, photographs, measurements, and a pass or fail conclusion. If it fails, the standard remedy is rework and a re-inspection at the supplier's cost.

How to write QC into your order

Put it in the proforma invoice:

• Quality standard: 100% inspection, AQL 2.5 major / 4.0 minor
• Size tolerance: ±1 cm
• Colour: matched to the approved sample
• Remedy: rework or credit for confirmed defects
• Evidence: photo report before shipment

Why this protects you

Without a defined standard, a dispute becomes one person's opinion against another's. With AQL written into the order and a photo report before shipment, you have an objective reference — and a checkpoint before the goods leave the factory, when fixing problems is still cheap.
