What does an inspection report contain?
A professional inspection report is not a one-line verdict; it is a decision file. The sections you should expect to find:
- Shipment details: factory name, purchase order, item description, lot size presented, inspection date and location.
- Completion and packing status: how many units were actually produced and how many were packed in final export cartons.
- Sampling plan: the standard used, inspection level, AQL per defect class, sample size, and the accept and reject numbers.
- Defect table: a description of every defect, its classification, and how many times it occurred in the sample.
- On-site test results: function, dimensional, pull, adhesion, carton drop and similar checks.
- Packaging and labelling: carton markings, barcodes, product labels, weights and dimensions.
- Photographs: defect images clearly cross-referenced to the defect table, plus packing, labelling and storage shots.
- Result: pass, fail, or pending and inconclusive.
If any of these is missing, the report is incomplete and is not a safe basis for a payment decision.
How do critical, major and minor defects differ?
| Class | Definition | Examples | Common AQL |
|---|---|---|---|
| Critical | Creates a safety hazard or breaches a legal or regulatory requirement | Exposed live wire, gas appliance leak, small part detaching from a children's toy, missing mandatory conformity marking | Zero |
| Major | Likely to cause failure, return or consumer complaint, or breaches a substantive specification | Function not working, colour deviation from the approved sample, open seam, dimension outside agreed tolerance | 1.5 or 2.5 |
| Minor | Deviates from specification without affecting function and rarely triggers consumer rejection | Light surface scratch, loose thread, slightly faint print in a concealed area | 4.0 |
The critical point: these classifications are not universal constants. They must be written down for your specific product before production starts. The same scratch may be minor on a workshop tool and major on a premium cosmetic product.
How do you calculate the accept or reject decision yourself?
A worked example: a lot of 3,000 units, General Inspection Level II, agreed AQLs of zero critical, 2.5 major and 4.0 minor.
- A lot of 3,000 falls in the 1,201 to 3,200 range, code letter K, sample size 125 units.
- At AQL 2.5 the accept number is 7 and the reject number is 8.
- At AQL 4.0 the accept number is 10 and the reject number is 11.
- Suppose the report records zero critical defects, 5 major and 9 minor.
- Result: critical zero, major 5 within 7, minor 9 within 10, so the lot passes statistically.
Had there been 8 major defects instead of 5, the lot would fail even with zero minor defects. Each class is evaluated independently; a low minor count never offsets an excess of major defects.
Why might you reject a lot that officially passed?
The formal result only compares counts against the sampling plan. The commercial decision is broader. Watch for these cases:
- A single repeating defect pattern: five major defects all of the same type signal a systematic line problem that will repeat across the uninspected remainder.
- Low completion rate: if the lot was only fifty percent complete, the sample does not represent what will actually ship.
- A failed on-site test: some tests sit outside AQL logic entirely, and one failure is enough to reject.
- A regulatory conformity gap: a missing label or conformity mark can stop the shipment at customs regardless of build quality.
- Packaging weakness: a carton unfit for a long sea voyage means well-made goods arriving damaged.
And why might you accept a lot that officially failed?
Because a fail is a statistical outcome, not a final verdict. If the failure comes from cosmetic minor defects in a market that does not care about them, and the delay cost in a peak season exceeds the defect cost, conditional acceptance with a discount or partial sorting may be the sounder commercial call. What matters is that the decision is deliberate and documented in writing, not a verbal concession that is forgotten by the next order.
What are your options when a lot fails?
| Option | When it fits | What to watch |
|---|---|---|
| 100% sorting then re-inspection | Scattered defects that can be screened visually | Sorting should be at the supplier's cost and independently supervised |
| Rework or repair | A repairable defect that does not compromise function | Agree a fixed deadline and mandatory re-inspection |
| Conditional acceptance with discount | Minor defects that will not affect sale | Document the concession in writing, for this lot only |
| Partial shipment | Part of the lot conforms and part does not | Separate quantities clearly in documents and packing |
| Full rejection | Critical defects or a general pattern of failure | Review contract and letter of credit terms before declaring formally |
Quick checklist when the report arrives
- Does the lot size in the report match the purchase order quantity?
- Is the completion and packing rate high enough to represent the shipment?
- Does the sampling plan, level and AQL, match what the contract specifies?
- Was each defect classified against your written definitions rather than the inspector's judgement?
- Are the defects scattered, or do they follow one repeating pattern?
- Are the photographs clear and cross-referenced to the defect table?
- Were all required on-site tests performed, with numeric results recorded?
- Are carton markings, barcodes and weights recorded and correct?
- Are there open findings that need a factory response before payment?
Practical takeaway
Do not read an inspection report starting from the verdict page. Read the sampling plan, then the defect table, then the photographs, then decide. The formal result tells you whether the numbers matched the agreed plan; the decision must weigh the defect pattern, your market's regulatory requirements and the cost of delay. At ALSHUMUL we issue reports with explicit defect classification, referenced photographs and a written recommendation, delivered before the balance payment falls due rather than after.
