What challenges do cold chain air freight operators face in 2025?
Cold chain air freight involves more than placing goods in an insulated container; it requires orchestration across airports, carriers and ground handlers. Industry experts warn that packaging alone cannot guarantee product integrity because handling errors, transit delays and inconsistent storage conditions expose cargo to extreme temperatures. Air cargo volumes are projected to grow by 5.8 % dans 2025 à 72.5 million tonnes, yet available cargo capacity will only increase by around 4.4 %, creating bottlenecks. This imbalance, coupled with geopolitical unrest and unexpected disruptions, means that the cold chain must be resilient.
Risks across the journey
Every stage of the journey introduces risks:
| Scène | Key risks | Signification pratique |
| Origin pick up & pre conditioning | Insufficient pre cooling can start shipments at incorrect temperatures; outdated infrastructure and synthetic refrigerants create inefficiencies. | Start shipments at the right temperature by conditioning goods and containers; invest in modern cold rooms and eco friendly refrigerants. |
| Airport hand over | Handling errors and prolonged tarmac exposure can cause temperature excursions. | Use rapid transfer corridors and dedicated cold chain zones to minimise tarmac time and maintain temperature. |
| Vol & transit | Limited cargo capacity and delays increase time in transit; dry ice restrictions (2.5 kg per passenger package and up to 200 kg sur les vols cargo) require careful planning. | Select optimal routes and carriers; ensure containers carry enough refrigerant and comply with dry ice limits and venting requirements. |
| Customs & border clearance | Complex customs procedures and documentation demands cause hold ups, exposing cargo to uncontrolled environments. | Prepare documentation in advance and utilise priority clearance programs; choose corridors with harmonised standards. |
| Livraison du dernier kilomètre | Final transfer to hospitals or retailers may lack cold rooms or trained staff; door openings create temperature spikes. | Train last mile providers, use GPS tracked vehicles with multiple temperature zones and emphasise strict procedures. |
Compliance burdens and security threats
Operators must navigate a labyrinth of regulations. Pharmaceutical shipments must comply with Good Distribution Practices (PIB), Analyse des risques et points de contrôle critiques (HACCP) pour la nourriture, les États-Unis. Loi sur la modernisation de la sécurité alimentaire (FSMA) and EU GDP / GMP Annex 11 exigences. IATA’s Temperature Control Regulations mandate the use of a Temps & Temperature Sensitive label and a Standard Acceptance Checklist for every shipment, Pendant que le CEIV Pharma/Fresh certification program ensures training, validated equipment and risk management. Airlines and shippers must also follow dry ice regulations—passenger flights permit only 2.5 kg de glace sèche par colis, whereas cargo flights may allow up to 200 kg—to mitigate CO₂ build up risks.
Security threats are rising too. Cargo theft incidents surged 27 % in the past year, and cyberattacks targeting digital logistics systems can disrupt operations. High value pharmaceuticals are attractive targets; donc, operators must integrate security screening, tamper evident packaging and cybersecurity measures.
Capacity and infrastructure constraints
Infrastructure at many airports is aging, with cold storage facilities built decades ago requiring upgrades and modernisation. Ageing refrigeration units use harmful refrigerants such as HCFCs and HFCs; regulatory pressure is forcing a shift toward sustainable refrigerants and energy efficient systems. Limited space at airports means cargo is sometimes stored in off airport facilities, which introduces new hand offs and potential breaks in the cold chain. The continuing e commerce boom adds volume—online sales will account for around 20.8 % of total retail in 2024 and are forecast to grow 14 % annually through 2026—pushing capacity even further.
Which technologies improve temperature controlled air cargo efficiency?
Advanced technology makes cold chain air freight possible by providing real time visibility and predictive insights. Dans 2025, investments in software that improves visibility across the supply chain are increasing. Below are the key innovations reshaping air freight cold chains.
Active and passive containers
Modern containers come in two broad categories:
| Type de conteneur | Description | Impact on your operations |
| Active containers | Equipped with battery powered cooling or heating systems; maintain internal temperature independently for long-haul flights. Often used for pharmaceuticals and biologics requiring narrow ranges (+2 °C à +8 °C or deep frozen). | Provide precise control and reduce risk of excursions during delays; cependant, they are heavier and more expensive. |
| Passive containers | Use insulated materials and phase change materials (PCMS) like gel packs or dry ice to maintain temperature. Suitable for shorter routes or when weight restrictions apply. | Lower cost and energy consumption but require careful payload preparation and accurate loading of refrigerants. |
More sophisticated designs combine vacuum insulated panels (Vips) with PCMs to extend hold time. VIPs are valued at roughly US$2.5 billion in 2025 and are projected to reach US$5 billion by 2033. PCMs provide precise temperature control and are reusable, offering longer cooling duration than gel packs.
IoT sensors and real time monitoring
Continuous monitoring is the backbone of a safe cold chain. IoT enabled sensors track internal temperature, humidité, shock and GPS location, sending alerts when excursions occur. Advanced systems display real time dashboards, provide environmental alarms and record audit trails to support regulatory compliance. Par 2025, the global market for cold chain tracking and monitoring is projected to reach €1.8 billion (source search result) as companies invest in visibility.
Predictive analytics uses historical data to forecast equipment failures and route specific risks. AI algorithms optimise flight schedules and resource allocation. The global AI market in logistics is expected to reach US$348.62 billion by 2032, highlighting its transformative potential.
Blockchain and transparent records
Blockchain technology creates tamper proof records of shipments, including temperature data at each checkpoint. Airlines using blockchain have reported a 7 % reduction in cargo handling costs and a 90 % decrease in communication errors. The immutable ledger ensures all stakeholders—from shippers to customs authorities—access the same trusted information, speeding up customs clearance and reducing paperwork. Sur 70 % of logistics firms plan to integrate AI with blockchain systems, demonstrating momentum toward unified digital platforms.
Smart cold chain management and autonomous logistics
Smart cold chain management integrates IoT sensors, real time monitoring and specialised insulated containers to ensure products maintain their required ranges. Rapid ramp transfers and minimised storage times reduce exposure to ambient conditions. Entre-temps, AI driven route optimisation and autonomous vehicles (including drone deliveries) reduce transit times and carbon emissions. These innovations not only protect goods but also cut costs and improve sustainability.
Sustainable refrigerants and eco friendly packaging
Environmental sustainability is a growing priority. Hydrofluoroolefins (HFOs) and CO₂ based refrigeration systems offer effective cooling with low global warming potential. Reusable insulation materials and recycled packaging minimise waste. Solar powered refrigeration units enable cold storage in regions with unreliable electricity supply. Many airlines also aim to replace at least 10 % of their fuel with Sustainable Aviation Fuel (SAF) par 2030; the EU aims for 2 % SAF use by 2025. While not directly controlling temperature, these measures reduce the environmental footprint of cold chain air freight.
How to comply with regulations and standards for cold chain air freight?
Regulatory compliance protects product integrity and avoids costly penalties. Dans 2025, global and regional frameworks set stringent requirements for temperature controlled air cargo.
Global regulations
Bonnes pratiques de distribution (PIB): WHO and EMA guidelines emphasise temperature control, validated systems and traceability.
Analyse des risques et points de contrôle critiques (HACCP): Identifies potential hazards in food transport and defines critical control points.
Loi sur la modernisation de la sécurité alimentaire (FSMA): Requires preventive controls and documentation for food manufacturers in the U.S..

Documentation & traçabilité: Maintain digital records of temperature logs, calibration certificates, training and deviations; blockchain can automate this process and provide audit trails.
Sops & entraînement: Develop standard operating procedures and provide regular training to all personnel involved in packing, handling and monitoring. CEIV training programs ensure consistency across the supply chain.
Contingency planning: Prepare back up power supplies, spare packaging materials and processes for transferring goods to alternate facilities during equipment failures.
What are the best practices for packaging and monitoring in air freight cold chain?
Proper packaging and monitoring are the foundation of safe cold chain air freight. Even the most sophisticated container will fail if mismatched to the product or route. Below are practical recommendations drawn from industry research and real world examples.
Match the product’s thermal profile
Médicaments, biologics and food products have distinct thermal classes. Match shipments to the correct packaging:
For vaccines and insulin (+2 °C à +8 °C), use standard refrigeration and PCMs.
For frozen foods and certain vaccines (–20 ° C), choose containers with dry ice or -20 PCM °C.
For ultra low biologics (–70 °C or lower), deploy cryogenic shippers and real time monitoring.
When planning multi leg flights, consider ambient conditions at each stop; shipping across hemispheres introduces wide temperature ranges and customs delays. Validate packaging through thermal modelling, including worst case scenarios, to ensure it maintains the required temperature even if a flight is delayed by 48 heures.
Conduct lane risk assessments and pre alerts
Evaluate each route’s potential risks—such as extreme climates, congested airports and lengthy customs processes—and select carriers with proven cold chain performance. Set up pre alert systems to notify ground handlers of incoming temperature sensitive shipments so they can allocate resources and expedite unloading.
Build redundancy
Carry sufficient refrigerant or backup PCMs for unexpected delays. When using passive containers, add extra gel packs or PCMs; for active containers, ensure battery backup or charging options. Redundancy also applies to equipment and personnel—have spare sensors, alternate carriers and trained staff ready to step in.
Embrace digital visibility
Leverage IoT monitoring platforms that integrate temperature sensors, humidity sensors and GPS tracking. Real time dashboards allow you to spot temperature excursions and respond immediately. Dans 2025, many companies are implementing visibility software across the entire supply chain, and some examples show that real time alerts prevented thousands of dollars of spoiled goods. Mobile apps enable customers to track shipments and verify conditions upon receipt.
Train and empower your team
Human factors remain critical. Train staff in packaging, sensor placement, SOPs and emergency procedures. Encourage a culture of accountability—any deviation should trigger immediate action. Document lessons learned from incidents and adjust procedures accordingly.
Use interactive tools and assessments
To engage your team and customers, provide interactive tools such as a container selection quiz (helps determine whether to choose active vs passive containers) et un lane risk assessment calculator. These tools can reduce decision making time and improve packaging accuracy, lowering the risk of temperature excursions. Consider including them on your website alongside this article.
Practical case study: A pharmaceutical distributor equipped every pallet with digital temperature sensors and set automated alerts. When a trailer door stayed open too long, the system notified the driver and warehouse. They closed the door quickly, preventing a temperature breach and saving thousands of dollars in perishable goods. This example illustrates how real time monitoring and training can avert losses.
How are sustainability and digital innovation reshaping air freight cold chain?
Cold chain air freight is undergoing a sustainable and digital transformation. La durabilité n’est plus une option; it influences customer choices and regulatory compliance. Digital innovation improves resilience and reduces waste.
Sustainable operations
The air cargo industry is adopting Sustainable Aviation Fuel (SAF); major airlines plan to replace at least 10 % of fuel with SAF by 2030, and the EU’s ReFuelEU initiative targets 2 % SAF usage by 2025. Some carriers offer reusable thermal packaging as part of a rental model; these containers reduce waste and carbon emissions but must balance practicality with reliability. Operators also invest in solar powered refrigeration units and eco friendly insulation materials.
Digital transformation and AI
Advanced analytics and AI optimize route planning, predict delays and manage capacity. AI driven cargo screening and predictive maintenance improve security and reduce human error. Dans 2025, AI algorithms are analysing traffic, weather and demand to recommend optimal schedules and anticipate high risk routes. Blockchain builds transparent, tamper proof records.

Insistance au marché
E commerce remains a critical growth engine. Online shopping represented around 20.8 % of retail in 2024 and is projected to grow 14 % chaque année à travers 2026. Cependant, analysts caution that overreliance on e commerce could leave a gap if growth slows. Capacity constraints persist—while air cargo volumes may rise 5.8 % dans 2025, available capacity is expected to increase only 3–4 %. Airlines are therefore investing in dedicated freighters and partnerships with third party logistics providers to balance demand.
Trade growth in emerging markets is creating new air freight corridors, particularly in Southeast Asia, Africa and Latin America. These routes require robust cold chain infrastructure, including temperature zoned storage rooms and rapid transfer corridors. Upgraded cold storage facilities and larger distribution centres near production areas are being developed to improve proximity to customers.
