Cold Chain Teams Told to Tier Monitoring by Shipment Risk

Global – October 27, 2026 -- Cold chain operators should tier monitoring by shipment risk, using QR indicators, electronic data loggers and connected devices at different levels instead of one technology on every lane, according to a guide on cold chain monitoring systems.
Indicators flag exceptions with the simplest workflow
WarmMark QR monitors cumulative exposure above a specified temperature, while FreezeSafe QR identifies exposure below a specified temperature. QR-enabled documentation captures information at selected hand-offs without requiring every user to download and interpret a complete data file.
Products vulnerable in both directions need both limits covered. ColdChain Complete is aimed at shipments where upper and lower thresholds must be monitored together.
