A named container is a container that starts with the ISO group code SN and is used for multipurpose containers that do not fall under any other ISO code groups. The ISO code is a standardized system used to identify different types of shipping containers.
Here under you can find the containers that have already a ISO code.

Livestock Carrier Container

 Live stock carrier containers are specialized containers that are designed for transporting livestock, such as poultry, cattle, and other animals. They are configured to meet the specific needs of the livestock being transported, and are available in different sizes and configurations to accommodate different types of animals.

Live stock carrier containers are identified by an ISO code that ends with the code “S0” (e.g. 28S0). This code indicates that the container is a live stock carrier container and helps to distinguish it from other types of containers. Live stock carrier containers are an important part of the global trade in livestock, and help to ensure the safe and humane transportation of animals.

Car Carrier Container

Car carrier containers are used to move cars by road and rail. However, in exceptional cases, the car carrier containers are used to ship by sea also. Generally, RORO (Role On Roll Off) shipping arrangements are done to move cars and other automobiles by sea. Under a RORO shipping, vehicles are directly driven on to RORO vessel. Compared to shipment of automobiles with car carrier containers, the cost of transportation is less in RORO shipping. Although the term car carrier container is used, almost all types of automobile vehicles can be transported in such containers by making necessary changes in manufacture.
This ISO container code ends with the code: S2 (e.g. 42S2)
