A defect found at the factory costs a rework hour. The same defect found in your warehouse costs freight, re-packing, a replacement run and a launch date. Found by your customer, it costs the program. Inspection is not a formality at the end of production — it is the cheapest insurance in the whole order.
This is what to inspect on cosmetic bags and pouches, in the order the standard works, plus the wording that makes the result enforceable.
1. How AQL actually works
AQL — Acceptable Quality Limit — is defined in ISO 2859-1. It does not mean "zero defects". It means: draw a statistically valid sample from the lot, count defects by class, and accept the lot if the count stays under a limit set by the AQL level. For sewn soft goods, the common working standard is General Inspection Level II, AQL 2.5 for major defects, AQL 4.0 for minor, and zero tolerance for critical.
| Lot size (pcs) | Sample to inspect | Accept / Reject at AQL 2.5 |
|---|---|---|
| 151 – 280 | 32 | 2 / 3 |
| 281 – 500 | 50 | 3 / 4 |
| 501 – 1,200 | 80 | 5 / 6 |
| 1,201 – 3,200 | 125 | 7 / 8 |
| 3,201 – 10,000 | 200 | 10 / 11 |
Read the middle column as a floor, not a ceiling. A 1,000-piece order gets 80 pieces pulled at random — from the top, the middle and the bottom of the pallet stack, not from the cartons nearest the door.
2. Defect classes, with examples that matter for bags
Classification is what decides whether a lot passes. Vague words like "poor quality" cannot be inspected against; each class needs concrete examples agreed before production.
| Class | Definition | Bag examples |
|---|---|---|
| Critical | Unsafe, illegal, or unusable | Sharp metal point inside the pouch; mould or chemical smell; wrong item entirely; broken zipper that cannot close |
| Major | Visible, affects sale or function | Logo in the wrong position or wrong size; shade difference between panels; skipped stitches; zip gapes when closed; lining loose at the seam; dimension outside tolerance |
| Minor | Noticed on close inspection, does not stop a sale | A single loose thread; slight print mottle on a dark ground; faint handling mark on the lining; carton scuffed |
The judgement call that sinks orders most often is the middle row: "how much shade difference is a defect?" Answer it before production with a physical standard — an approved shade band or the sealed pre-production sample — and state it in the spec as "no visible difference against the approved standard under D65 lighting".
3. The eight inspection sections
Quantity and packing
Count against the packing list. Check polybag, hangtag, tissue, individual box, barcode label and carton markings. Confirm the carton count and that the shipping mark matches the PO — this is where a mixed-size carton creates weeks of delay at destination.
Appearance and colour
Inspect under standard lighting, not factory fluorescent tubes alone. Look for shade variation between panels of the same piece, between pieces, and between the body and the trim. On printed goods check registration, ink coverage and position against the approved sample.
Dimensions
Measure the agreed points — length, height, gusset, handle drop, zip opening. State the tolerance in the spec; ±5 mm on sewn soft goods is realistic, ±2 mm is not, and asking for ±2 mm invites either a false report or a price increase.
Material
Confirm the material actually used: fabric weight (GSM), backing, PU thickness, whether the lining is the specified one. Feel for stiffness differences between pieces from different rolls.
Construction and stitching
Check stitch density (roughly 8–12 stitches per inch), evenness of topstitching, bartacks at zip ends and handle attachments, seam alignment, and that the lining is secured — not just caught at the opening.
Zipper and hardware function
Open and close every sampled zip. It must run smoothly, close fully with no gap, and not catch at the ends. Check the slider finish matches spec, the puller is the approved one, and that D-rings, snaps and rivets are properly set and do not turn or pull through.
Logo and decoration
Position, size, colour and method against the approved sample. For print, check that the method is what was specified — a heat transfer substituted for screen print is a major defect, not a cosmetic one. For embroidery, check for puckering and that small text is legible.
Carton and drop test
Check carton strength, weight and the drop test result (typically one carton dropped from a set height on a corner, an edge and a face). Then open it: the goods inside should still be saleable.
4. The defects that actually cause rejections on cosmetic bags
- Shade variation between panels — the most common rejection in dyed and printed goods, and the most avoidable through one dye lot per order.
- Print position drift — a logo 5 mm off centre is invisible on one piece and obvious across a shelf of fifty.
- Zip gape — the opening does not fully close, usually a slider or zip-length issue that a fifty-piece pilot run would have caught.
- Lining not attached at the seam — looks perfect flat, bags out the first week in use.
- Odour — a chemical smell from adhesive or from material packed too soon. Treated as critical: it does not wash out, and it transfers to the product the pouch is meant to hold.
- Dimension creep — the first cartons are correct and the last ones are 8 mm short as the line relaxes.
5. Third-party inspection: when it earns its cost
Major inspection houses — SGS, Bureau Veritas, Intertek, QIMA — will send an inspector to the factory for a day and issue a report with photos, a defect count and a pass or fail. For a first order with a new supplier, or any order going straight to a retail customer's DC, it is money well spent.
Book it as soon as production is 80–100% complete and packed — too early and the inspector sees half a lot; too late and the container is already booked. Send the inspector your spec, the approved sample reference and the packing list. An inspector without your standard inspects against theirs.
6. The three sentences that make rejection enforceable
Inspection only has teeth if the purchase order says so. Three clauses cover almost everything:
- Standard: "Goods shall be inspected to ISO 2859-1, General Inspection Level II, AQL 2.5 major / 4.0 minor, critical defects zero. The approved pre-production sample is the reference standard for appearance and colour."
- Right: "The buyer may conduct or appoint a third-party inspection before shipment; the seller bears the cost of re-inspection if the first inspection fails."
- Remedy: "Failed lots shall be reworked or replaced within [X] working days; payment of the balance is due only on a passed inspection."
That third clause is the one that matters commercially, and it works both ways: GAOHE's standard terms are 50% deposit with the order and 50% before shipment, with no credit terms for any customer — so tying the balance to a passed inspection gives the buyer protection without asking the factory to finance the order.
The short version
Define the standard before production: AQL level, defect classes with concrete examples, the sealed approved sample, and the measurement tolerances. Inspect a random sample from across the lot, not the nearest cartons. Use a third-party inspector on the first order and on anything going straight to retail. Put the standard, the inspection right and the remedy into the PO — and the conversation about defects stops being an argument about opinion.
