What is ISO Tank Container?

ISO tank also known as ISO tank container. ISO tank containers are used to transport and store hazardous and non-hazardous materials such as liquids, powders and gases. 

ISO tanks are made of stainless steel and feature insulation as well as aluminum or polyurethane protective layers . This makes them a safe choice for transporting a variety of materials


An ISO tank container is a type of container used to transport bulk liquids, chemicals, and gases in an intermodal shipping container. 

The term "ISO" refers to the International Organization for Standardization, which sets the standards for the design, manufacturing, and testing of these containers. 

ISO tank containers comply with the ISO standards to ensure uniformity and compatibility with various modes of transportation.


Key features of ISO tank containers include:

  • Standardization: ISO tank containers adhere to standardized dimensions and specifications, making them compatible with various transportation modes such as ships, trains, and trucks.

  • Material: They are typically made of stainless steel or carbon steel, providing strength and durability to handle the transportation of liquids and gases.

  • Capacity: ISO tank containers come in various capacities, ranging from a few thousand to several tens of thousands of liters, depending on the specific requirements of the cargo.

  • Design: The containers are designed to be stackable, facilitating efficient storage and handling when not in use.

  • Safety: ISO tank containers are designed with safety features, including pressure relief valves and secure closures, to ensure the safe transport of hazardous materials.

  • Modes of Transport: These containers can be easily transferred between different modes of transport without the need for unloading and reloading the cargo. This intermodal flexibility is a key advantage.

  • Fittings: ISO tank containers are equipped with standardized fittings for easy loading, unloading, and monitoring of the cargo.

Advantages and Disadvantages of ISO Tank Container

Advantages of ISO Tank Containers:

  • Intermodal Compatibility: ISO tank containers are designed to be compatible with various modes of transportation, including ships, trains, and trucks, allowing for seamless and efficient movement of cargo across different transport networks.

  • Standardization: Adherence to international standards ensures uniformity in design, manufacturing, and testing, making ISO tank containers widely accepted and easily interchangeable.

  • Safety: ISO tank containers are equipped with safety features, such as pressure relief valves and secure closures, to ensure the safe transport of hazardous materials. This contributes to the overall safety of the transportation process.

  • Cost-Effective: The standardized design and construction of ISO tank containers make them cost-effective for both manufacturers and shippers, as they can be easily handled, stored, and transported.

  • Reduced Handling: The intermodal nature of ISO tank containers minimizes the need for multiple handling processes. The container can be transferred directly from one mode of transport to another, reducing the risk of product contamination or damage.

  • Stackability: ISO tank containers are designed to be stackable, which optimizes storage space when they are not in use, whether at shipping terminals or storage facilities.

  • Flexibility: These containers can transport a wide range of liquids, including chemicals, food-grade products, and liquefied gases, making them versatile for various industries.

Disadvantages of ISO Tank Containers:

  • Initial Investment: Acquiring ISO tank containers can involve a significant upfront cost, especially for businesses or industries that require a large fleet for regular transportation needs.

  • Limited Routes for Certain Goods: While ISO tank containers are versatile, there may be restrictions on the transportation of certain hazardous or sensitive materials on specific routes, which could limit their use in some cases.

  • Cleaning and Maintenance: After transporting certain types of cargo, ISO tank containers may require thorough cleaning to prevent contamination of subsequent loads. Maintenance, inspection, and cleaning processes add to operational costs.

  • Weight Limitations: ISO tank containers have weight limitations based on international standards. This can be a constraint for certain types of cargo, especially those with high density or weight.

  • Specialized Handling Equipment: Loading and unloading ISO tank containers may require specialized handling equipment, and not all ports or facilities may be equipped to handle them, potentially causing delays or additional costs.

  • Environmental Impact: In the event of accidents or spills, the transportation of hazardous materials in ISO tank containers can pose environmental risks. However, the safety features incorporated into the containers are designed to minimize such risks.

Despite these disadvantages, ISO tank containers remain a widely used and efficient means of transporting bulk liquids, chemicals, and gases globally.


What do you need to pay attention to?

  • - Highly corrosive products, few tank owners are willing to rent short term, such as high concentration of sulfuric acid, sodium hydroxide solution, although this product is classified as class 8, but because of its highly corrosive, so it will lead to difficult to rent to ISO tank container, this product is best or manufacturers provide their own.

  • - There are special odors, particularly difficult to clean products such as dimethyl disulfide such rotten egg smell, and particularly difficult to clean the product, the tank owner will generally increase the price of the tank set.

  • - Some products can be volatile at room temperature and may be dangerous when reloading, so such products need to be filled with inert gas and sealed when using ISO tank containers for transportation.

  • - ISO tank containers are not exportable by any manufacturer, even if they are qualified for production. Because the port of Shanghai when exporting canned dangerous goods, filling manufacturers need to record in the customs, only qualified manufacturers can do the record.

ISO tank containers are designed to be versatile and can be transported using various modes of transportation. The intermodal nature of these containers allows for seamless movement across different transportation networks. 

Here are the common ways in which ISO tank containers can be transported:

Maritime (Ship): ISO tank containers are often transported by sea on container ships. They are loaded onto the vessel and secured in accordance with maritime safety standards. This mode is particularly suitable for long-distance transportation between countries and continents.

Rail (Train): ISO tank containers can be loaded onto flatbed railcars for transportation by train. Rail transport is an efficient way to move large quantities of cargo over land, and ISO tank containers are designed to fit securely on standard railcars.

Road (Truck): Trucks equipped with suitable chassis can transport ISO tank containers on roads. This is a common method for transporting goods from ports to final destinations or between different logistics hubs. Specialized trucks with twist-lock mechanisms secure the containers to the chassis.

Intermodal Transportation: ISO tank containers are specifically designed for intermodal transportation, meaning they can be easily transferred between different modes of transportation without the need for unloading and reloading the cargo. For example, a container arriving by ship can be seamlessly transferred to a train or truck for further inland transportation.

Multimodal Transportation: This involves using a combination of different transportation modes, such as sea and rail or road and rail, to transport ISO tank containers from the point of origin to the final destination. Multimodal transportation optimizes the efficiency of the logistics chain.

Container Depots and Storage: ISO tank containers can be stored at container depots when not in use or awaiting transportation. These depots often have facilities for cleaning, inspecting, and maintaining the containers.

It's important to note that the handling and transportation of ISO tank containers require specialized equipment, including cranes for loading and unloading at ports, flatbed railcars, chassis for trucks, and other intermodal infrastructure. 

Additionally, safety regulations and international standards must be followed to ensure the secure and efficient movement of goods in ISO tank containers.

Before transportation, shippers must also consider factors such as the type of cargo, required safety measures, and compliance with regulatory requirements for the specific goods being transported.Shawn.Liao(Mr.)
