A pre-production inspection checks materials, components, tooling, approved samples and production readiness before the main manufacturing run starts.
How the control works
Use it when incorrect inputs would make later inspection too late or expensive. The inspector should verify that controlled specifications and samples are available at the line.

| Control | Use it when incorrect inputs would make later inspection too late or expensive. The inspector should verify that controlled specifications and samples are available at the line. |
| Evidence | Retain material identities, quantities, certificates, tooling condition, line setup, approved sample, open issues and start authorization. |
| Tradeoff | A readiness visit should not be reported as a finished-goods inspection. It confirms inputs and preparation, not completed output. |
