The short answer
Evaluate a sample against a written specification, not appearance alone. Check capacity, dimensions, closure fit, decoration, handling and packing before approving production.
A sample can be a catalogue reference, a prototype or a production sample. Each answers different questions. Ask how it was made and which features represent the intended production process.
Review the complete pack
Inspect the bottle with the actual cap, liner, pump or stopper. Check stability, label application and handling. Use the intended contents and filling process for suitability trials agreed with the relevant specialists.
Record approval conditions
Photograph the sample, identify its revision and note deviations. Sign off only the features that have been demonstrated. A visual prototype should not be treated as proof of production tolerances or long-term product compatibility.
Procurement checklist
- Record sample type, date and revision.
- Measure agreed critical dimensions.
- Trial the actual closure and label.
- Document appearance limits and unresolved items.
- Keep an identified approval sample.
Common question
Is one attractive sample enough to approve a bulk order?
It is not a substitute for an agreed specification and production inspection plan. Use the sample as a reference, then define the checks and evidence required for the production batch.
