Incoming Material Control: Quarantine, Sampling and Release
A simple, visible incoming-control system prevents unapproved raw materials and packaging components from entering production.
Identify every delivery
Record supplier, material, supplier lot, received quantity, date, condition and internal identity. Labels should remain legible and connected to the receiving record. Similar containers and names require extra attention to prevent mix-ups.
Use physical and system status
Quarantine, released and rejected status should be obvious both in records and at the storage location. Electronic status is not enough if operators cannot see which container is approved. Physical labels alone are not enough if inventory records allow the wrong lot to be issued.
Plan representative sampling
Define who samples, where sampling occurs, which tools are used and how contamination is prevented. The sampling plan should reflect material form, number of containers and risk. Samples must remain traceable to the delivery and container population.
Review documents and tests
Compare the certificate and supplier information with the approved specification and purchase requirement. Perform the planned identity or quality checks. Record actual results and the acceptance decision rather than relying on a verbal confirmation.
Control partial use and returns
If containers are opened, record quantity issued, resealing, storage and remaining status. Material returned from production should not silently re-enter stock. Define how it is identified and assessed before reuse.
Handle nonconforming deliveries
Segregate rejected or suspect material, document the issue and decide on return, investigation or disposal. Supplier communication should reference the exact lot and evidence. The aim is both containment and prevention of repeat problems.
