Types Of Shipping Containers

Shipping containers come in a wide range of formats designed to support diverse cargo types and transport conditions. These intermodal containers are built for seamless movement across ships, trains, and trucks, making them essential to global logistics. From general freight to specialized goods, each container type serves a specific purpose based on how it's loaded, what it carries, and how it travels. This guide introduces the most common container types used in global logistics.
Different type of shipping containers serves different purposes. the red containers in the picture are general purpose container that do not require temperature control. The white reefer container, Refrigerated shipping containers have built-in cooling systems to maintain specific temperatures for temperature-sensitive cargo during transport.

Dry (General Purpose) Containers

Dry containers, often referred to as general purpose containers, are fully enclosed units designed to protect cargo from the external environment. They are the most commonly used container type for transporting goods that do not require temperature control or special handling.

this is a dry (general purpose) container. Most commonly used container type for transporting goods that do not require temperature control or special handling.

General purpose containers are widely available and compatible with standard handling and transport systems. Thanks to their availability and straightforward design, they are typically the most cost-effective option (see our container pricing guide to compare costs across different container types).

High Cube Containers

High cube containers are similar in structure to standard dry containers but are built with extra height to increase internal volume. This design allows for more space without altering the container’s footprint, making them useful for certain types of bulky or lightweight cargo.

High cube containers are similar in structure to standard dry containers but are built with extra height to increase internal volume. This design allows for more space without altering the container’s footprint, making them useful for certain types of bulky or lightweight cargo.

High cube containers are commonly selected when volume capacity is more important than weight limits.

Open top containers

Open top containers feature a removable cover instead of a solid roof, allowing goods to be loaded from above. This configuration is useful when cargo is too tall or irregularly shaped to fit through standard doors, or when it must be lifted into place by crane. A tarpaulin or similar material is typically used to secure and protect the load.

Other Specialized Container Types

While the container types above are widely used, additional formats exist for specific applications.

Half-height containers

These are shorter containers designed to carry dense cargo that does not require full-height space. Their reduced profile allows for easier loading and unloading of heavy materials.

Car carrier containers

Car carrier containers are configured to safely transport vehicles. They may include internal fittings or supports that help secure one or more vehicles during transit.

Cargo storage roll containers

These are mobile containers designed for short-distance movement of goods, often used within warehouses or distribution centers.

Swap body containers

Swap bodies are used primarily in European intermodal transport. Unlike ISO containers, they are not always stackable and are optimized for road and rail use.

Intermediate bulk containers (IBCs) and drums

These containers are used for shipping smaller quantities of liquids or powders. They are often stackable and designed to be handled efficiently in storage and transport operations.

Radioactive and hazardous material containers

Specialized containers are built to transport hazardous or regulated materials safely. They comply with international standards for containment, labeling, and handling of dangerous goods.

ISO Codes And Container Abbreviations Explained

All shipping containers are marked using standardized ISO 6346 codes, which include the owner code, serial number, check digit, and type identifier. Abbreviations such as GP (general purpose), HC (high cube), RF (refrigerated), OT (open top), and TK (tank) help identify the container’s design and function at a glance.

Container Shipping Standards And Classifications

Shipping containers must meet international standards that support safety and compatibility across transport modes. These include ISO specifications for sizing and construction, CSC certification for structural integrity, and TIR and DNV classifications for specific transit and offshore requirements. These frameworks ensure containers can be used safely and consistently around the world.

Shipping Container Sizes

Shipping containers are produced in standardized sizes to streamline handling and logistics. Common lengths include 10-foot, 20-foot, 40-foot, and 45-foot units. These dimensions allow for predictable capacity planning and ensure compatibility with global shipping and transport infrastructure.

Container Usage Beyond Shipping

Beyond their original logistics function, shipping containers are widely adapted for alternative uses. They can be seen as storage units, temporary offices, emergency shelters, or modular structures for retail and housing. Their durability and modular design make them a popular choice for both commercial and personal projects.

Frequently asked questions

There are over a dozen standard container types used in global logistics. These include general purpose (dry) containers, high cube containers, refrigerated (reefer) containers, flat racks, open tops, open side containers, double door containers, ISO tank containers, and insulated or thermal containers. In addition, there are specialized formats such as car carriers, half-height containers, cargo roll containers, swap bodies, and hazardous material containers.

General purpose (dry) containers are typically the most cost-effective option. Their simple design, high availability, and widespread use make them more affordable compared to specialized containers like reefers, tanks, or open-side units.

The most popular container type worldwide is the 20-foot or 40-foot general purpose container. These units are used across nearly every industry for transporting goods that don’t require temperature control or special handling.

The standard dry container – also referred to as a general purpose or GP container – is the most common type. It is fully enclosed, weatherproof, and suitable for most cargo that can be loaded through end doors.

ISO containers are built to international standards (ISO 668) that ensure uniform sizing, stacking, and transport compatibility across global shipping networks. Conex containers, originally developed for U.S. military use, may refer to similar steel containers but do not always conform to ISO standards. Today, “conex” is often used informally in North America to describe storage containers, whether or not they are ISO-compliant.
