Quick Answer
Cold chain logistics is the management of temperature-sensitive cargo — including pharmaceuticals, food, and perishables — under controlled environmental conditions from origin to destination. The CargoLinked freight marketplace connects shippers with verified freight forwarders who specialise in cold chain and temperature-controlled international shipping.
What Is Cold Chain Logistics?
Cold chain logistics is the specialised branch of supply chain management that ensures temperature-sensitive products are stored, transported, and delivered within defined temperature limits at every stage of the journey. A break in the cold chain — even a few hours outside the specified temperature range — can render an entire pharmaceutical batch unusable, destroy food quality, or trigger costly regulatory consequences.
The global cold chain logistics market exceeded $285 billion in 2025 (Source: Allied Market Research) and is growing at over 7% annually, driven by pharmaceutical biologic growth, expanding fresh food trade, and the rise of e-commerce perishables.
Temperature Ranges in Cold Chain Shipping
| Temperature Range | Common notation | Typical cargo |
|---|---|---|
| Deep frozen | −60°C to −90°C | mRNA vaccines, certain biotech samples |
| Frozen | −18°C and below | Frozen food, ice cream, frozen biologics |
| Chilled | 2°C to 8°C | Fresh produce, dairy, vaccines, biologics |
| Controlled Room Temperature (CRT) | 15°C to 25°C | Some pharmaceuticals, sensitive chemicals |
| Ambient (conditioned) | 8°C to 25°C | Confectionery, wine, some cosmetics |
Note: Always refer to your specific product's storage specification (typically on the Technical Dossier or product label) rather than category defaults. A 1°C deviation from the specified range can affect product stability and regulatory compliance.
Cold Chain Transport Options
Ocean Freight: Reefer Containers
A reefer container (refrigerated container) is the standard solution for cold chain ocean freight. Modern reefer containers:
- Maintain a pre-set temperature from −30°C to +30°C throughout the voyage.
- Connect to the vessel's power supply (or a shore power supply at port terminals).
- Include internal data loggers that record temperature readings throughout the voyage — essential for pharmaceutical GDP compliance.
- Are available in 20ft and 40ft sizes; 40ft high cube reefers are most common for pharmaceuticals and food volumes.
Pre-trip inspection (PTI): Reefer containers should be pre-cooled to the set temperature and inspected before loading. Always request confirmation that a PTI has been performed before your cargo is loaded.
Reefer cargo rates: Reefer containers command a premium over standard dry containers — typically $500–$2,000 per container more on major trade lanes, depending on temperature requirements and market conditions.
Air Freight: Temperature-Controlled Options
For time-sensitive or high-value cold chain cargo (particularly pharmaceuticals), air freight is often the preferred mode despite the higher cost.
Air freight cold chain options:
- Passive (insulated) packaging — Temperature-controlled packaging with dry ice or gel packs maintains the specified range for a defined duration (typically 24–96 hours). Suitable for short transit times.
- Active (powered) container — Temperature-controlled aircraft containers (e.g., Envirotainer, CSafe) with integrated refrigeration that actively maintain temperature regardless of ambient conditions. Required for pharmaceuticals requiring 2–8°C over long intercontinental routes.
- Temperature-controlled holds — Some aircraft types have temperature-controlled belly hold sections; not universally available.
IATA CEIV Pharma certification: Look for forwarders and ground handlers with IATA CEIV Pharma certification — the international standard for pharmaceutical air freight quality management.
Road Freight: Refrigerated Trucks
For domestic inland transport and cross-border regional cold chain, refrigerated (reefer) trucks are the standard solution. In Southeast Asia, refrigerated truck networks are well-established for food distribution but less mature for pharmaceutical distribution outside Singapore and major Malaysian cities.
Cold Chain Regulations by Cargo Type
Pharmaceutical Cold Chain
Pharmaceutical cold chain is the most regulated segment. Applicable frameworks include:
- WHO GDP (Good Distribution Practice): The international baseline for pharmaceutical distribution. All parties in the distribution chain — forwarders, handlers, carriers — must operate within a GDP-compliant framework.
- EU GDP (EU Directive 2013/C 68/01): Mandatory for medicines entering the European Union. Requires temperature-controlled storage and transport, qualification of transport lanes, and temperature excursion management procedures.
- US FDA guidance on pharmaceutical distribution: Less prescriptive than EU GDP but increasingly aligned. FDA expects manufacturers and distributors to validate the cold chain for all temperature-sensitive biologics and vaccines.
- Validation studies: Pharmaceutical companies must perform transport lane validation studies demonstrating that the packaging and transport method maintain the required temperature range for the full expected journey duration, including delays and seasonal temperature extremes.
Food and Perishables Cold Chain
Food cold chain is regulated by destination country food safety authorities:
- HACCP (Hazard Analysis and Critical Control Points): The internationally recognised food safety management framework. Logistics providers handling food must operate HACCP-compliant facilities and procedures.
- Temperature logging and documentation: Commercial importers typically require a continuous temperature log from the cold chain provider covering the entire international transit.
- Phytosanitary certificates: Required for fresh fruit, vegetables, and plant-based products in most countries.
- Country-specific requirements: The EU Food Hygiene Regulations, US FDA Food Safety Modernisation Act (FSMA), and other regional frameworks impose specific obligations on importers and logistics providers.
Choosing a Cold Chain Freight Forwarder
Not all freight forwarders are qualified for cold chain operations. When evaluating a cold chain forwarder:
Essential qualifications
- GDP certification (for pharmaceutical cargo) — Verify against the relevant national GDP authority register, not just the forwarder's own claims.
- IATA CEIV Pharma (for pharmaceutical air freight) — The international benchmark for pharmaceutical air cargo.
- IATA Perishable Cargo Regulations (PCR) compliance — For food and perishable air freight.
- Established reefer container relationships — Preferred agreements with carriers for priority reefer container allocation, particularly important during periods of reefer container shortages.
Key questions to ask
- What is your temperature excursion management procedure? (How do you respond when a temperature deviation occurs during transit?)
- Can you provide a validated transport lane study for my origin-destination corridor?
- What temperature monitoring systems do you use — passive data loggers or real-time telematics?
- Do you have pre-cooled warehouse facilities at origin and destination?
- Which airlines/shipping lines do you use for pharmaceutical temperature-controlled cargo?

Common Cold Chain Failures and How to Prevent Them
| Failure mode | Typical cause | Prevention |
|---|---|---|
| Temperature excursion during transit | Reefer malfunction, power interruption at port | Pre-trip inspection; continuous monitoring; redundant data loggers |
| Delay at port/airport exceeding packaging capacity | Customs hold, flight delay, vessel rolling | Conservative package duration rating; pre-clearance where possible |
| Loading/unloading at ambient temperature | Insufficient pre-cooling time, poor terminal practices | Pre-cool loading dock; specify handling procedures in shipper's declaration |
| Temperature excursion during road transport | Driver stops engine (stops power to refrigeration unit) | Specify continuous run requirement; use standby power units |
| Incorrect temperature set point | Forwarder sets wrong temperature on reefer | Written temperature specification in booking instructions; double-check PTI |
| Documentation failure | Missing temperature log, GDP record gaps | Specify documentation requirements at booking; verify before shipment releases |
Cargo Insurance for Cold Chain Shipments
Standard cargo insurance policies exclude losses attributable to the inherent nature of perishable goods. For cold chain shipments, ensure your cargo insurance policy specifically covers:
- Temperature excursion losses
- Mechanical breakdown of refrigeration equipment
- Power failure at port terminals
Specialist marine insurers offer "all-risks including temperature" coverage for pharmaceutical and food cargo. For high-value pharmaceutical shipments, the premium difference between standard and enhanced coverage is typically small relative to the cargo value. See our guide on cargo insurance for full details.
Frequently Asked Questions
What is cold chain logistics?
Cold chain logistics is the management of temperature-sensitive products throughout the supply chain — from manufacture to end consumer — under controlled environmental conditions. It encompasses refrigerated warehousing, temperature-controlled transport (reefer containers, refrigerated trucks, temperature-controlled aircraft holds), monitoring, and documentation to ensure the cargo maintains a consistent temperature throughout transit.
What temperature ranges are used in cold chain shipping?
The main temperature ranges used in international cold chain logistics are: Frozen (−18°C or below) for frozen food and ice cream; Chilled (2°C to 8°C) for fresh produce, dairy, and most pharmaceutical biologics; Controlled Room Temperature (15°C to 25°C) for certain pharmaceuticals and sensitive chemicals; and Deep Frozen (−60°C to −90°C) for mRNA vaccines and specific biotech products.
What is a reefer container?
A reefer container (refrigerated container) is a standard intermodal shipping container fitted with an integral refrigeration unit that maintains a precise, pre-set temperature throughout the ocean voyage. Reefer containers require access to a power supply (from the vessel, port terminal, or generator) at all times. They are available in 20ft and 40ft sizes and can maintain temperatures from −30°C to +30°C.
What regulations apply to international pharmaceutical cold chain shipments?
Pharmaceutical cold chain shipments must comply with WHO Good Distribution Practice (GDP) guidelines, country-specific GDP regulations (EU GDP, US FDA guidelines), IATA Perishable Cargo Regulations (PCR) for air freight, and cold chain validation requirements that demonstrate the packaging system can maintain required temperatures for the full journey duration plus a safety margin.
Do I need a specialist freight forwarder for cold chain shipments?
Yes. Cold chain shipments require a freight forwarder with specific GDP certification (for pharmaceuticals), established relationships with reefer-capable shipping lines or temperature-controlled air cargo handlers, temperature monitoring capabilities throughout transit, and experience in the documentation and regulatory requirements for your cargo type and destination market.
