Buyer note: A supplier QC report, factory photograph or video does not by itself establish formula identity, market compliance or future batch consistency. Confirm the exact product, evidence scope and release requirements for each project.
QC checkpoints
| Stage | Buyer should confirm | Hold when |
|---|---|---|
| Formula and raw materials | Formula code or revision, material identity, lot traceability and release status. | Product identity or release status is unresolved. |
| Bulk product | Appearance, color, viscosity and other agreed results against the approved specification. | Results fall outside the signed specification. |
| Filling and closure | Fill method, closure, batch coding and packaging-component version. | Fill, closure or coding differs from the approved reference. |
| Packaging and cartons | Label, artwork, shade breakdown, units, carton marks and recorded weights. | Artwork, SKU, quantity or packing differs from the order. |
| Documents | Product description, formula/batch references and destination-market documents. | Required information is missing or inconsistent. |
