What challenges plague pharma cold chain logistics tracking in 2025?
Rising costs and supply chain fragility. In 2025, 63 % of pharmaceutical manufacturers report raw material prices rising by more than 22 % since 2022. Nearly 58 % of active ingredient suppliers are concentrated in three Asian countries, creating single point failure risks when climate events or geopolitical tensions disrupt sourcing. These disruptions contribute to a 12 % product recall rate and US$35 billion in annual losses from temperature excursions.
Talent shortages. About 40 % of organisations face critical shortages of digital logistics and advanced therapy production staff. Without skilled personnel, deploying new tracking technologies becomes difficult.
Temperature diversity. Different drug classes require unique storage windows: vaccines and insulin need 2–8 °C, biologics often require freezing below –20 °C, while cell and gene therapies demand –80 °C to –150 °C. Managing multiple temperature bands across complex routes increases the risk of excursions.
How temperature ranges impact logistics
Temperature control isn’t one size fits all. The table below summarises common ranges, example therapies and practical implications for you.
| Temperature range | Example products | Typical shipping modes | What it means for you |
| 2–8 °C (Refrigerated) | Standard vaccines, insulin, GLP 1 agonists (demand grew 300 % since 2023) | Refrigerated trucks, insulated coolers | Requires reliable short term storage; failure leads to potency loss and recalls |
| Below –20 °C (Frozen) | Many biologics and specialty drugs | Power redundant freezers, passive containers with phase change materials | Packaging must maintain the range for 120+ hours, increasing logistical complexity |
| –80 °C to –150 °C (Cryogenic) | CAR T cell therapies, mRNA vaccines | Liquid nitrogen dewars, dry ice shippers | Demands specialised containers and rapid transport; small fluctuations can destroy million dollar batches |
| 15–25 °C (Controlled room temp) | Many tablets, diagnostic reagents | Insulated cartons, standard containers | Often overlooked; ambient shipments still require monitoring because heat waves or cold snaps can push them outside specification |
Practical tips and advice
Map your thermal profile: Document temperature limits for each product; this guides packaging choices and route planning.
Choose validated containers: Vacuum insulated panels and phase change materials can protect shipments for over 120 hours.
Plan for emergencies: Develop procedures covering delays, route changes and power failures; include instructions for adding dry ice or transferring products when sensors show drift.
Invest in training: Human error is a major contributor to deviations; ensure drivers, warehouse staff and technicians know how to handle products and respond to alerts.
Partner with experts: Experienced third party logistics providers offer infrastructure and expertise to maintain the cold chain.
Case study: During the pandemic, a biotech firm shipping CAR T therapies used AI optimised routing and real time IoT sensors. When a blizzard threatened delivery, the system rerouted the truck and alerted a backup driver. The therapy arrived within its 72 hour viability window, preventing a multi million dollar loss.
How do IoT sensors and blockchain enable real time visibility?
Traditional cold chain monitoring relied on data loggers and periodic manual checks, revealing problems only after a shipment arrived. Today, IoT (Internet of Things) devices collect continuous temperature, humidity, shock and location data, streaming it to cloud platforms. This shift provides early warning of excursions and deep visibility across the supply chain.
Core components of IoT enabled monitoring
