How to Read an AQL Inspection Report for Hotel Supplies
ByHcProduct Manager
The direct answer: a pass or fail on an AQL inspection report is decided by comparing the defects found in a random sample against standard acceptance numbers — most hotel amenity buyers specify AQL 2.5 for major defects and 4.0 for minor defects under General Inspection Level II, with zero tolerance for critical defects. This guide shows how to read the report line by line, with a worked example you can hand to your own suppliers.
Buyers often hear 'we do AQL inspection' from suppliers but rarely get shown what that means on paper. AQL — Acceptable Quality Limit — is the sampling standard behind almost every third-party inspection (SGS, Bureau Veritas, QIMA and their peers), and reading the report is a skill that takes ten minutes to learn and prevents expensive disputes later. Here is the anatomy of the report, using an amenity order as the worked example.
1. The five lines that decide pass or fail
| Report field | What it means | Worked example |
|---|---|---|
| Lot size | Units produced or shipped under the inspection | 10,000 pairs of hotel slippers |
| Inspection level | How the sample size is derived (Level II is the normal default) | General Inspection Level II |
| Sample size code letter | Table row for the lot size at that level | Code letter L |
| Sample size | Units actually inspected, drawn at random across cartons | 200 pairs |
| Accept / Reject numbers | Defect counts that pass or fail the lot, per AQL class | AQL 2.5: accept 10 / reject 11. AQL 4.0: accept 14 / reject 15 |
The sample is not one pile: inspectors pull cartons at random from across the stack — front, middle, back, top and bottom — so a carton-level packing error cannot hide. If the lot were larger, say 12,000 units, the code letter and sample size step up (315 units at Level II), and the acceptance numbers rise with it. This is why a supplier cannot 'promise' a sample size — it follows mechanically from the lot size and level.
2. Critical, major, minor: what counts in amenities
| Class | Definition | Typical examples in hotel supplies |
|---|---|---|
| Critical | Safety, legal or hygiene risk | Mould on textiles, leaking chemical bottles, sharp edges, missing SDS-relevant labelling — accepted count is always zero |
| Major | Affects function or guest perception | Slipper sole detached at the toe, pump that fails to prime, wrong size printed on packaging, toothbrush missing from a sealed kit |
| Minor | Cosmetic, guest would rarely notice | Label skewed a few degrees, faint scuff on a bottle, slight shade variance between cartons |
3. A worked example
Your 10,000-pair slipper order is inspected before shipment. The inspector pulls 200 pairs at random and records: 0 critical, 6 major (soles bonding weak on 6 pairs from one carton cluster), 12 minor (light scuffs). Compare against the acceptance numbers: major 6 ≤ 10 passes AQL 2.5; minor 12 ≤ 14 passes AQL 4.0. Result: PASS, with a note that the weak-bonding cluster is carton-localised and worth monitoring on the next run. Now flip it: 13 major defects found → 13 > 10 → the lot FAILS AQL 2.5, and the standard remedies are a 100% re-sort at the factory's cost followed by re-inspection, or — at your option — a price concession or rejection of the shipment.
4. Red flags on a supplier's own QC report
- 1Sample size smaller than the table requires for the lot — e.g. 60 pieces on a 10,000-unit order is not an AQL Level II inspection, it is a glance.
- 2Zero minor defects recorded. Real production always has some cosmetic variance; a spotless sheet usually means nobody actually counted.
- 3No photographs. Credible reports attach photos of every major defect found and the carton sampling positions.
- 4Report dated before production was complete, or before the packing list was final — it cannot describe the shipped goods.
- 5No AQL or inspection level stated at all; 'QC passed' with no sampling basis is marketing, not inspection.
Frequently Asked Questions
What AQL should I specify for hotel amenities?
Start with Level II, AQL 2.5 major / 4.0 minor, critical at zero — it is the standard most factories are calibrated to. Textiles with visible stitching can be tightened to 1.5 for majors, but tighter levels raise re-sort frequency and cost.
Is AQL inspection the same as 100% inspection?
No. AQL is statistical sampling — the sample stands in for the lot. If you need every unit checked (for example, individual sealed kits going into a luxury flagship), that is a separate 100% check priced and scheduled differently.
Who pays for a third-party inspection?
Typically the buyer books and pays the inspection firm directly — booking keeps the inspector independent of the factory. It is usually a flat day-rate per man-day, small relative to the shipment value it protects.
What happens if a shipment fails inspection?
The standard sequence: factory re-sorts or reworks the defects at its own cost, then the lot is re-inspected (often against tightened acceptance numbers). Build the re-inspection window into your delivery schedule — it typically costs a few days, which matters against a 15-20 day production lead time.
