The supplier is not the manufacturer.
Match the material, grade, manufacturer site and supplier relationship the purchase actually requires.
Keep qualification scope, specification version, required certificates and transport conditions with the expected receipt. A familiar supplier name should not obscure a different manufacturer, site or material grade. Agree which system owns purchasing, qualification and the material definition.
Sampling follows the received population.
Resolve the approved plan against the containers that actually arrived.
Record container selection, sampling location, quantity, tools, resealing and custody. Preserve the contributing containers for composite samples. Sampling and identity-test coverage depend on the approved strategy; the twelve-container illustration is not a universal sampling rule.
Certificates and site results have different sources.
Keep supplier claims distinguishable from your laboratory’s evidence.
Reconcile the CoA to the material, manufacturer lot, specification, units and methods. Preserve imported values and extraction review. Connect the site’s samples and approved results without treating a supplier certificate as an automatic release or silently replacing an unresolved test.
Eligibility follows the container into use.
Carry the authorised status, expiry or retest condition and remaining quantity into storage and dispensing.
Record physical movement separately from a status change. Retain partial receipts, splits, returns and rejected containers with their original lot relationships. Agree how holds and release decisions reach inventory, labels and downstream workflows, including reconciliation when an interface fails.
