Sampling is a stock movement.
Keep the withdrawal, sample identity, remaining quantity and custody together.
Record what was actually removed from each container. Link returned material, retained samples and waste to their own movements; do not assume unused sample material is eligible to return to stock.
Returns do not automatically become available.
A returned container may have a different handling and exposure history.
Capture seals, condition, location, time outside controlled storage and relevant excursion evidence. Route eligibility back through the appropriate quality assessment before reallocation.
Pick for the work that needs it.
Connect production requirements, reservations, container identity and physical picking.
Define the lot-selection and expiry rules, then verify the actual location, handling unit and quantity at pick time. Keep kit assembly, staging and delivery to the batch traceable. A plan or reservation is not evidence that the material was physically moved.
Keep custody beyond the storage location.
Retain the conditions and handoffs needed to assess storage, shipment, returns and recall scope.
Connect temperature or excursion evidence to the affected containers and time window. Record shipment quantities, recipients and the required checks before dispatch. Keep count discrepancies and stock adjustments attributable so genealogy can be followed both into and out of a batch.
