A certificate is useful only when a laboratory can connect it to the material that was actually received. A receiving record and a simple chain-of-custody process preserve that connection from delivery through storage, internal transfer, and final disposition.
Before the shipment arrives
- Create a purchase record containing the supplier, order number, item description, expected quantity, and expected delivery date.
- Identify the staff member or controlled receiving location authorized to accept the package.
- Save the supplier’s published shipping and documentation terms as they existed when the order was placed.
At receipt: document before changing anything
- Record the carrier, tracking number, delivery date and time, receiving person, and package condition.
- Photograph visible damage, broken seals, moisture, or labeling problems before opening or discarding packaging.
- Record the product name, quantity, container count, label details, and every batch or lot identifier exactly as printed.
- Compare the received identifiers with the packing record and available analytical report.
- Quarantine any item with a mismatch, missing identifier, damaged container, or unexplained documentation gap until the discrepancy is resolved.
Match the analytical documentation
The batch or lot identifier is the bridge between the physical container and its report. Confirm that the identifier on the report exactly matches the identifier on the received material. Also record the testing laboratory, report number, test date, methods, reported results, and document revision if shown.
Do not substitute a historical or example report for a current batch record. If a website displays a report without a clear batch match, retain it only as general reference material and request the correct documentation from the supplier.
Create a controlled internal record
Assign a unique internal receiving number without replacing the supplier’s original batch identifier. Your record should preserve both values. Store the original report as a read-only file, record its source URL or delivery method, and note when it was downloaded or received.
- Supplier and order number
- Internal receiving number
- Supplier batch or lot identifier
- Container count and labeled amount
- Receipt date, receiving person, and condition
- Report filename, report number, laboratory, and test date
- Storage location and any internal transfers
- Discrepancies, investigation notes, and resolution
Preserve custody during storage and transfer
Record where the material is stored, who can access it, and when it moves. Each transfer entry should include the date, person releasing the material, person receiving it, quantity transferred, source container, destination container if applicable, and reason for transfer. Corrections should remain traceable; do not silently overwrite the original record.
What authoritative guidance contributes
FDA bioanalytical guidance emphasizes documenting reference materials, certificates, purity, stability, batch information, manufacturer, receipt, use, and storage. NIST definitions distinguish general reference materials from certified reference materials and explain that a certificate must document specified properties and traceability. Those concepts are useful for record design, but a commercial research material should not be described as a certified reference material unless it actually meets that definition.
Disposition and retention
At the end of the internal lifecycle, record the remaining quantity, disposition date, method, and responsible person. Retain purchase, receipt, analytical, custody, discrepancy, and disposition records according to your laboratory’s documented policy and applicable requirements.
