This checklist covers what to verify at the pre-production stage and what to document so the factory and the buyer are aligned before a single production unit is made.
What a pre-production inspection covers
The PPI checks whether the factory is actually ready to run the order correctly. It looks at inputs (materials, components, samples, tooling) rather than outputs. By the time finished goods are available to inspect, the cost of a mistake is already baked in.
A PPI typically involves the QC team, the production supervisor, and sometimes the buyer's technician or agent. All findings must be documented and signed off before production is authorized to start.
Raw materials and components
Verify that all materials required for this order have arrived and match the approved specifications:
- Check material descriptions, colors, grades, and weights against the approved spec or purchase order
- Verify supplier labels and certificates where required: fabric composition, country of origin, chemical compliance
- Inspect for visible defects: wrong shade, damaged rolls, mixed materials from different batches
- Confirm quantities are sufficient for the full order, including cutting loss allowance
Do not rely on the supplier's delivery note. Inspect the physical goods against the written specification.
Approved samples and production standards
The production line cannot run without a clear reference point. Confirm the following are physically present on the factory floor:
- Approved pre-production or golden sample, signed off by the buyer
- Counter sample or sealed sample used for final approval reference
- Approved artwork files or print proofs for any printed components
- Spec sheet with key measurements, tolerances, and workmanship requirements
If the approved sample is missing or cannot be located, production must wait. Running without a reference sample means every inspector on the line is working from memory or interpretation.
Production team readiness
Check that the workers assigned to this order understand the product and the quality requirements:
- Have the line workers been briefed on critical quality points for this style?
- Is there a workmanship standard or defect guide visible at each station?
- Have new techniques or unfamiliar operations been practiced before the run starts?
- Is the correct SOP posted or available at each production station?
A line that has not been briefed on a new product will produce consistent output, but consistently wrong. Ten minutes of pre-run alignment prevents hours of sorting and rework.
Equipment and tooling checks
Verify that the equipment required for this order is available, calibrated, and set up correctly:
- Confirm the correct needles, threads, or blades are fitted and match the spec
- Check that machinery settings (stitch density, tension, temperature) match the approved parameters
- Verify that any measuring tools or gauges used for quality checks are calibrated and within tolerance
- Inspect tooling for wear: a worn cutting die or bent needle will produce consistent defects across the entire run
Documentation to complete before production starts
The pre-production inspection must produce a written record before the line is authorized to start:
- Pre-production inspection report: findings, photos, and sign-off
- List of any open items: issues found during the PPI that require resolution before or during the run
- Production hold notice: if any critical issue was found, this document formally stops the line until the issue is resolved
- Authorization signature: both the QC team lead and the production supervisor sign that the line is cleared to start
A verbal 'it looks fine' is not a record. If a post-shipment dispute refers back to this point in the process, you need a document, not a memory.
How to handle a pre-production hold
If the PPI finds a problem that cannot be resolved before production starts (wrong material, missing approved sample, equipment out of tolerance), issue a formal hold.
The hold notice specifies the exact issue, who is responsible for resolving it, and the target resolution date. Production does not start until the hold is cleared and re-signed.
A PPI hold that delays production by a day is cheaper than a failed final inspection on a completed 10,000-unit order. Document the hold, resolve the cause, and clear it in writing.
Key takeaways
- Run the PPI before the line starts, not partway through the first batch.
- Verify raw materials against the approved specification, not just the supplier's delivery note.
- Confirm the approved sample is physically present on the floor before authorizing production.
- Document every finding and get written sign-off from both the QC team and the production supervisor.
- A PPI hold that delays production by a day is cheaper than a failed FRI on a finished 10,000-unit order.
