Direct answer

What should buyers know first?

A pre-production inspection checks whether materials, components, approved samples, tooling and production instructions are ready before mass production begins. It is most useful when errors would be expensive to correct after the line starts.

For: Buyers preparing a new product, new supplier or materially changed production run.

Key planning facts

Timing
Before mass-production materials and capacity are fully committed
Reference
Approved sample, bill of materials and current specification
Decision
Start, correct or hold production

What to take into the project

  • Confirm the factory has the current specification.
  • Match incoming materials to approved requirements.
  • Close discrepancies before line start.

Reconcile the approved inputs

Check the current drawings, sample version, materials, colours, labels and packaging instructions at the factory.

Check production readiness

Review tooling, equipment, capacity, operator instructions and planned quality checkpoints for the actual order.

Record the start decision

List missing or non-conforming inputs, assign owners and hold the start decision when a critical issue remains open.

Frequently asked questions

Is this the same as a factory audit?

No. An audit assesses general capability; a pre-production inspection checks readiness for a specific order.

Can it verify raw materials?

It can compare observable materials and documents within scope; laboratory tests may still be required.

What if production has already started?

Use a during-production inspection and focus on work in progress, defects and corrective action.
