Incoming goods inspection
Incoming goods inspection explained: what goods-in inspection means, what gets checked, and how much of it you actually need
Incoming goods inspection is the conformity check carried out on materials, components or finished products at the point of receipt, before they are booked into stock or released to production, to confirm that what arrived matches what was ordered and conforms to the agreed specification. It is the last point at which a supplier's problem is still cheap to hand back.
Common variants of the name: goods-in inspection, receiving inspection, incoming quality control, IQC, goods receipt inspection. One distinction worth holding on to. The goods receipt is a logistics transaction, counting the delivery and booking it against the purchase order. The inspection is a quality decision about whether the material is fit to use. Plenty of warehouses do the first and call it the second.
What does incoming goods inspection check?
- Identity. Part number, drawing revision, batch or lot number, and where relevant the serial numbers. The right quantity of the wrong revision is the classic goods-in miss.
- Documentation. Certificate of conformity, material or mill certificates, test reports, calibration certificates, dangerous goods paperwork, country of origin.
- Quantity and packaging. Count against the delivery note and the order, packaging integrity, pallet condition, transit damage, seal numbers.
- Condition. Visible damage, corrosion, contamination, moisture ingress, temperature excursion on cold chain, shelf life remaining against the specified minimum.
- Specification. Dimensional checks, functional test, and attribute sampling against an agreed acceptance quality limit.
- Disposition. Accept to stock, quarantine, reject and return, or accept under a documented concession with the engineering authority's signature.
Where it sits in ISO 9001
Clause 8.4 of ISO 9001:2015 covers control of externally provided processes, products and services, and 8.4.2 requires the organisation to determine the type and extent of control based on the potential impact on its ability to deliver conforming product. Read carefully, the standard does not mandate that you inspect every delivery. It mandates that you can explain why the control you applied is proportionate to the risk. That is the clause that justifies waving through a proven supplier and screening a new one, provided the reasoning is written down and the supplier data supports it.
Incoming goods inspection: a worked example
A distributor receives 2,400 circulating pumps against a purchase order. Goods-in confirms the count, the part number and revision, and that the certificates of conformity cover the batch numbers on the cartons. For the functional and cosmetic characteristics the agreed plan is general inspection level II at AQL 0.65: a lot of 1,201 to 3,200 gives sample size code letter K, a sample of 125 units, with an acceptance number of 2 and a rejection number of 3. Two nonconforming pumps in the 125 and the delivery is accepted. Three and the whole 2,400 goes to quarantine, not just the three.
How to reduce incoming inspection without losing control
Checking everything from every supplier forever is not a quality strategy, it is a staffing problem. The recognised routes out:
- Skip-lot sampling. ISO 2859-3 specifies procedures for reducing inspection effort on high-quality product from a supplier with a satisfactory quality system, by determining at random, with a specified probability, whether a lot is accepted without being inspected at all.
- Reduced inspection under the switching rules. ISO 2859-1 allows a move to reduced inspection once the switching score reaches 30 and production is steady, and pulls you straight back to normal the moment a lot fails.
- Dock to stock and ship to stock programmes. Qualified suppliers deliver direct to the line, with the control moved upstream into supplier approval, process audits and part approval submissions.
- Supplier certification and audit. Verification of the supplier's own final inspection records replaces repeating the work at your dock.
In every case the control moves upstream. It does not disappear, and the audit evidence has to show where it went.
What goes wrong at goods-in
- No written acceptance criteria, so the decision falls to whoever happens to be on the dock that afternoon.
- No physical quarantine location, so rejected stock stays pickable and gets used.
- Damage found after the carrier's claim notification window has closed, which for many contracts is measured in days.
- Findings recorded on paper and never trended by supplier, so a chronic problem reads as a string of unrelated one-offs.
- Inspecting the pallet that was easy to reach rather than a random sample, which quietly invalidates the plan.
Capturing the evidence while the pallet is still open
The practical constraint at goods-in is timing. The evidence has to be captured in the minutes the pallet is open, by whoever is standing there, and it has to be good enough months later to support a supplier debit, a carrier claim or a concession decision. Venta Capture, a product of VentaVid, is used for exactly that gap: the receiving operator is walked through a defined sequence of views and questions on their own phone, and the submission arrives as a structured, timestamped case with the images, answers and integrity information attached, ready for the quality engineer to review or to send back a targeted retake request. It does not make the accept or reject call. The qualified person still does that, against the specification. And the receipt timestamp records when the submission arrived, not when the damage happened.
