8.6.4IATF 16949:2016

Verification of externally provided product (IATF only)

Plain-language summary

Purchased product conformity gets assured by a defined mix: receiving inspection, supplier data with verification, assessments/audits, certificate review — your choice, but documented and risk-matched.

What the clause is really asking

Use one or more of the listed methods (statistical receiving data, inspection/testing on sample, second/third-party assessments paired with conformance records, part evaluation by accredited lab, customer-agreed method) to confirm incoming product quality.

What auditors look for

Auditors ask which method applies to which supplier/part and why, then sample the records of that method actually operating.

Typical evidence

Documented incoming verification scheme per part/supplier; records of the selected method in use.

How to comply — recommendations

Map every purchased part class to its verification method in one table — the logic visible, the records routine. Skip-lot rules tied to scorecard status close the loop.

Common nonconformities

No defined method per part; certificates accepted unreviewed as the 'method'; lab tests by unaccredited labs.

In the book

Chapter 8Operation — Where the Product Is Won or Lost treats this clause family in full: what it is really asking, what auditors look for, the evidence that satisfies, how to make it work on a real floor, and where companies stumble. This IATF requirement is covered in the Automotive Edition, in the same six blocks as the ISO clause around it.
