On this page you will find information on the different types of standard shipping containers as well as basic internal and external dimension data.
The data provided here are derived from standards developed by the International Organization for Standardization (ISO). The information presented here should be used for guidance purposes only. Please be aware that the actual specifications of any given container may vary from these and from the containers provided by individual carriers.
High-cube general purpose containers are similar to standard containers except for their greater height. While a general purpose container has a maximum height of 2591 mm (8'6"), a high-cube general purpose container has a height measurement of 2896 mm, or 9'6". Most high-cube general purpose containers are 40' long.
A hard top container has a removable steel roof which can make it easier pack and unpack the container using a crane. The roof can also be lashed to the wall of the container to allow for the shipment of over-height cargo. The hard top container comes in 20' and 40' length as well as in the taller high cube configuration.
Flatracks are essentially containers without roofs or side walls along their lengths, but with floors that have been designed for high loading capacity. The end walls of flatracks are designed to still support stacking and can support cargo lashings. Some flatracks feature fixed end walls or collapsible walls. Flatracks are available in 20' and 40' lengths and are also produced in high cube configurations.
A platform is similar to a flatrack but has no side or end walls. Platforms are designed with extremely heavy cargo in mind and thus have a much higher loading capacity through a reinforced floor. This means that large weights can be concentrated on small areas of the platform surface. Platforms are produced in 20' and 40' lengths.
A refrigerated container, also known as a 'reefer' is a special type of container that contains a built in refrigeration unit for controlling its internal temperature. The refrigeration unit can be powered by an internal or external generator known as a genset. Alternatively, the unit can be powered from a container ship's own power supply.
