Core document pack
A practical minimum set often includes the order reference, invoice or release note, shipment tracking, lot list, COA packet, receiving log, storage log, and any deviation or quarantine notes.
Documentation and traceability: keeping every batch linked from receipt through release.
Traceability is less about one perfect document and more about whether each record points cleanly to the next. This guide helps teams keep that chain intact.
Document flow
The strongest systems connect documents in both directions: from a received lot back to the shipment, and from the shipment forward into storage, handling, and internal lab records.
Internal changes
Whenever material is relabelled, moved, subdivided, or re-documented, log who made the change, when it happened, and what internal identifier connects the new record to the original lot.
Traceability test A simple audit question is: can a third party reconstruct the path of this batch from one file set without verbal explanation?
Retention
Retention periods vary by workflow, but the principle is consistent: keep enough records to reconstruct receipt, storage, and release decisions later without relying on memory.
