Reefer Containers: Sizes, Costs & How They Work in 2026

Quick Overview

A reefer container, short for refrigerated container, is an insulated shipping container with an integrated refrigeration unit that keeps temperature-sensitive cargo within a controlled temperature range during ocean, road, and rail transportation. 

Reefer containers are commonly used for fresh produce, frozen foods, seafood, pharmaceuticals, dairy products, meat, flowers, and other temperature-sensitive goods. Unlike standard dry containers, reefers continuously manage temperature, airflow, and ventilation throughout transit.

Key Facts about reefer containers at a glance:

• Reefer containers are commonly available in 20-foot and 40-foot sizes.
• They use an integrated refrigeration unit to maintain the required cargo temperature.
• Typical applications include food, pharmaceuticals, seafood, meat, dairy, and fresh produce.
• Reefers can support both chilled and frozen cargo, depending on the equipment specification.
• Cargo must be pre-cooled when required because a reefer is designed primarily to maintain temperature.
• Reefer freight costs are generally higher than dry-container freight.
• Proper temperature settings, ventilation, airflow, and monitoring are critical to prevent cargo damage.

Reefer Container Sizes

The two most common ocean-freight options are 20-foot standard reefers and 40-foot High Cube reefers.

Reefer Type	Approx. Capacity	Typical Use
20' Standard Reefer	28.3 m³	Smaller temperature-sensitive shipments
40' High Cube Reefer	67.5 m³	Larger commercial shipments
40' High Cube Super Freezer	Up to 86 m³*	Deep-frozen cargo

*Capacity varies by equipment specification. Always confirm the exact unit available from the carrier.

A reefer generally has less usable internal space than a dry container of the same nominal size because the refrigeration machinery takes up part of the container.

Critical Considerations for Reefer Cargo

Before booking, exporters should confirm the required temperature, ventilation, pre-cooling, and cargo loading requirements for their product.

Cargo should be loaded at the appropriate transport temperature and positioned to allow proper airflow. Incorrect loading or blocked air passages can create temperature variations and damage the cargo.

For India-USA shipments, exporters should also account for port dwell time, customs clearance, vessel transit, and inland delivery when planning a reefer shipment.

Reefer Container Temperature Range

The required temperature depends entirely on the cargo.For example, a carrier may offer standard reefers with operating ranges around -30°C to +30°C, while specialized super-freezer equipment can operate at much lower temperatures.

However, exporters should not select a reefer simply based on its maximum temperature range.

The cargo's required transport temperature, pre-cooling requirement, ventilation setting, and acceptable temperature variation should determine the equipment choice.

Factors That Affect Reefer Shipping Rates

Ocean freight: Reefer rates are usually higher because carriers incur additional equipment, energy, and handling costs.

Port and terminal charges: Reefer cargo can attract additional terminal and monitoring charges.

Electricity and monitoring: Reefers need continuous power while connected at terminals, creating additional operating costs.

Destination services: Drayage, storage, inspections, and delivery requirements can increase the total landed cost.

Seasonality: Agricultural seasons and peak demand can significantly affect reefer equipment availability and pricing.

A brand new refrigerated (reefer) container generally costs between $28,000 and $48,000, while used reefer containers typically cost between $9,000 and $22,000, depending heavily on size, condition, and the refrigeration unit manufacturer.

What Should Exporters Check Before Booking?

Before booking, exporters should confirm:

• The required temperature range.
• Whether the cargo needs ventilation.
• Whether the cargo must be pre-cooled.
• Packaging and airflow requirements.
• Reefer plug availability at origin and destination.
• Carrier-specific reefer acceptance requirements.
• Temperature control and documentation requirements.
• Emergency procedures in case of equipment failure.

Temperature-sensitive cargo also needs careful planning around customs clearance and inland transportation because delays can increase the risk of product deterioration.

For general container loading and securing practices, exporters can refer to the IMO/ILO/UNECE CTU Code.

Reefer vs Dry Container: Which Should You Use?

The decision depends on whether the cargo needs active temperature control.

Requirement	Reefer Container	Dry Container
Temperature control	Yes	No
Refrigerated cargo	Suitable	Not suitable
Frozen cargo	Suitable with appropriate equipment	Not suitable
General dry cargo	Usually unnecessary	Suitable
Freight cost	Higher	Lower
Equipment complexity	Higher	Lower

If the product can tolerate normal ambient conditions, a dry container will usually be the simpler and more economical option.

Key Considerations When Booking a Reefer

Reefer bookings require more operational planning than standard FCL bookings.

Exporters should provide accurate commodity information, required temperature, ventilation settings where applicable, and any special handling instructions. Incorrect information can lead to booking problems, cargo damage, or additional charges.

For India-US shipments, exporters should also coordinate the reefer booking with port handling, customs clearance, vessel schedules, US drayage, and final delivery.

How Intoglo Helps

For India–USA FCL shipments, Intoglo coordinates ocean freight, documentation, customs coordination, inland transportation, and shipment visibility.

For temperature-sensitive cargo, the key is planning the equipment, routing, documentation, and delivery timeline together.

Conclusion

Reefer containers allow exporters to move temperature-sensitive cargo across long distances while maintaining controlled conditions. Standard 20-foot reefers offer around 28.3 m³ of capacity, while 40-foot High Cube reefers provide around 67.5 m³, with equipment-specific temperature ranges extending from approximately -30°C to +30°C.

For exporters, the practical takeaway is simple: choose the reefer based on the cargo's temperature, ventilation, capacity, and routing requirements rather than container size alone.
