Production Step 03
Sampling converts the development plan into a physical product reference. Sensory, appearance, fill and packaging points are reviewed together.

Sample approval
The approved sample provides the reference for formula, appearance and packaging. Required adjustments should be documented before the production specification is released.
Sample review
Approval criteria depend on the dosage form and project scope.
| Review area | What to check | Reference output | Approval effect |
|---|---|---|---|
| Sensory | Taste, aroma, mouthfeel or texture | Approved sensory reference | Formula lock |
| Appearance | Shape, color, surface and finish | Approved visual reference | Process and tooling lock |
| Fill | Weight, volume or piece specification | Approved fill target | Production specification |
| Packaging | Container, closure, label and carton | Approved pack reference | Artwork and packing lock |
| Documentation | Sample notes and required changes | Approval record | Batch release basis |
Approval sequence
Each review point becomes part of the approved production reference.
