What is receiving inspection?

What it is

Receiving inspection is how you satisfy yourself that what arrived is what you ordered, before it becomes part of what you ship.

ISO 9001 handles it in clause 8.4, control of externally provided processes, products, and services. Clause 8.4.2 requires you to determine and apply verification activities that ensure externally provided product meets requirements. Clause 8.4.1 requires you to evaluate, select, monitor, and re-evaluate your suppliers against criteria you define.

What the standard does not do is tell you to inspect everything. Verification is risk-based. A certificate of conformance from a supplier with five years of clean history may be sufficient verification for a commodity fastener. A first article from a new supplier on a critical dimension is not verified by a piece of paper.

The decision is yours to make. What the standard requires is that you made it deliberately, wrote it down, and follow it.

When you will hear it

In a customer audit, often. Receiving is a favorite starting point for supplier quality auditors because it is where the paper trail either begins properly or does not.

In a nonconformance investigation, when the root cause turns out to be material that should never have been released to production.

In a supplier scorecard conversation, where receiving data is the evidence base for whether a supplier is performing.

What the auditor expects to see

Defined criteria. What gets inspected, how much, against what, and who decided. A sampling plan if you sample.

Records that match the criteria. If the procedure says dimensional check on critical characteristics, the record has to show the dimensions, not a checkmark.

Control of material that has arrived but is not yet verified. Physically or systemically, unverified material must not be usable. A rack of untagged parts next to the production line is the finding that writes itself.

Evidence you use the results. Supplier performance monitoring under 8.4.1 is meant to be fed by what receiving finds. If your receiving records show repeat problems from one supplier and the supplier list never changes, an auditor will ask why.

Common mistakes

Inspect everything, record nothing. Common in shops with experienced receiving staff who catch problems by eye. Without records, none of it is verification as far as the standard is concerned.

Accepting a certificate of conformance as universal proof. It is a supplier's assertion. For a critical characteristic, an assertion is not verification.

No segregation of unverified material. Speed pressure at the dock is where this breaks, and the consequence shows up three operations later.

Treating customer-supplied material like your own. Consigned material is customer property and carries extra obligations on identification and on reporting damage or loss.

FAQ

Do we have to inspect every incoming lot?

No. You have to define verification activities proportionate to risk and follow them. Skip-lot sampling, certificate review, and full inspection can all be correct for different parts.

Does a supplier's ISO 9001 certificate mean we can skip verification?

It is one input into your supplier evaluation under 8.4.1, and it can justify reduced verification. It is not a substitute for having decided what verification you perform.

Who can perform receiving inspection?

Whoever your process says, provided competence records support it. If the check involves measurement, the person needs the training and the equipment needs to be calibrated.

What if we find a problem after the material is already in production?

That becomes a nonconformance with an extent-of-condition question attached: what else from that lot is already in product, and where did it ship.
