Quick answer. A third-party inspection is arranged against a defined standard, at a defined point in the process, with a defined consequence for a fail. The standard and the consequence are agreed before the inspection rather than after the result, because an inspection without an agreed remedy is a report rather than a control.
1. When the inspection happens
- After production is complete. Not partially finished, and not mid-run.
- After packing. Because the pack is part of what the customer receives.
- Before loading. Which is the point at which the result can still change what happens to the shipment.
- Not instead of during-production checks. A final inspection catches defects; an in-line check prevents the batch that contains them.
2. What has to be agreed first
- The standard. AQL sampling to ISO 2859-1, with the inspection level and the acceptable quality limit named.
- The defect classes. Critical, major and minor, defined before the inspection rather than after a result is disputed.
- The sample size. Which follows the lot size and the level rather than being a fixed number.
- The scope. Which styles, colours and quantities are covered by the inspection.
- The remedy. Replacement, credit or rework, and its effect on the schedule.
3. Who inspects, and why it matters
- An independent agency. The result is independent of the production, which is what makes it useful to a buyer who is not on site.
- The buyer’s own representative. Direct control, at the cost of the travel and the availability.
- The supplier’s QC. Useful as an internal check, but it is not a third-party verification of the supplier.
- Record which one it was. Because what the result proves depends on who produced it.
4. What to ask for after the inspection
- The report. With the standard, the level and the defect classes as applied.
- The photographs. Particularly of any defect found, since the classification is what the remedy turns on.
- The measurements. Where the inspection covered them, against the points of measure in the specification.
- The classification of findings. Which defects were critical, major or minor, and how each was counted against the limit.
- The recommendation. Pass, fail, or pass with a condition — and what the condition is.
5. What happens on a fail
- The remedy applies. Which is why it was agreed before the inspection rather than after it.
- The schedule moves. Rework or replacement has a lead time, and the effect belongs in the plan rather than in the conversation.
- The decision is documented. Whether the shipment is held, partially shipped or released with a concession.
- The process change follows. A repeat of the same defect indicates the stage that produced it has not changed.
6. Common errors
- Booking an inspection without a standard. The report arrives and there is nothing to measure it against.
- Defining the remedy afterwards. Which turns a control into a negotiation.
- Inspecting before packing is complete. The shipment then differs from what was inspected.
- Using the inspection as the only check. A final inspection describes the batch; it does not correct the stage that produced the defect.
- Not recording who inspected. The evidential value depends on the independence of the inspector.
- Treating a pass as a system assurance. It describes this lot, not the next one.
7. How to compare two suppliers
- The same standard and defect classes. Otherwise the two results are not comparable.
- The same inspector independence. A third-party result and an internal check are different kinds of evidence.
- The same point in the process. After packing and before loading, on both sides.
- The same remedy on a fail. Since that is what the inspection is protecting.
- The same reporting set. Report, photographs, measurements and classification, on both sides.
