A cold chain package needs an identity that links its physical contents to the relevant packing and exposure records. A temperature label or container name alone cannot establish which product, configuration and data were used. Keep that association intact from preparation through receipt.
Define the package identity
Record shipment and package identifiers, product and lot identity, and the instruction used. With several parcels in one order, retain the association between each parcel and its actual contents. Do not assume a shipment-level record describes every package identically.
Use the product-specific controls and actual transport requirements. Food, medicines and specimens can need different records and responsible assessment.
Connect the relevant evidence
| Package detail | Record association |
|---|---|
| Contents | Product, presentation, lot and quantity. |
| Configuration | Actual container, coolant, layout and preparation. |
| Device | Which logger or indicator belongs to this package? |
| Exposure | Relevant packing, transport and receiving period. |
| Transport data | Actual package quantities and applicable marks. |
| Receiving | Condition, observations and authorized decision. |
A device serial number should be usable in the record rather than left as an unexplained value on an unpacked logger. Resolve missing or conflicting identifiers before accepting the evidence.
Maintain the link through handoffs
- Check package and order identity at release.
- Retain the actual preparation and loading record.
- Keep required marks and identifiers readable.
- Record material interventions or repacking.
- Associate receiving observations with the correct parcel.
- Preserve the relevant data and any uncertainty.
If a parcel is opened, repacked or assigned another device, record the change through the defined process. Do not silently attach a favorable temperature file from another package.
Use evidence for the correct decision
Review the whole relevant trace against the product’s criteria. A final temperature reading can leave earlier exposure unanswered. A tracking event may help reconstruct custody without measuring product conditions.

Check route riskWHO: qualification of shipping containers is a pharmaceutical container qualification framework. It supports the technical assessment within its scope, not a general release decision for every cold chain parcel.
Correct identification also does not repair a damaged primary package or an unsupported configuration. Investigate the actual parcel and retain the responsible product assessment.
Frequently asked questions
Can one logger file be assigned to any parcel in the shipment?
No. Preserve the actual device-to-package association and justified evidence coverage.
Does a cold chain label prove the full temperature history?
No. Use the relevant measured exposure and records.
Can a missing identifier be ignored if the product feels cold?
No. Resolve uncertainty through the applicable assessment process.
Connect parcel identity with execution
Use the assembly sequence guide for packing records and the pharmaceutical handoff guide for route information transfer.
