What is an ISO Tank Container? [+types & dimensions]

18 Mar.,2024

 

What are ISO tank containers?

Tank containers are used to ship and store hazardous and non-hazardous materials such as liquids, powders, and gasses. ISO tanks are made out of stainless steel, with insulation, as well as a protective layer of aluminum or polyurethane. This makes them a safe and secure option for transporting a wide variety of materials.

ISO tanks are equipped to transport the following:

  • Liquids
  • Gasses
  • Powders
  • Chemicals
  • Perishable and non-perishable food items
  • Alcohol
  • Non-alcoholic liquids

If you’re a shipper, make sure you invest in a tank container that’s classified by the International Maritime Dangerous Good Code (IMO). This classification helps to identify and separate dangerous goods from other kinds of cargo. Check out this blog to learn all about IMO types for tank containers.

Safety and efficiency are synonymous with ISO tank containers. Apart from the fact that tanks can ship a considerable amount of bulk effortlessly, they’re also extremely durable. A tank container is designed to have a long life span, typically around 20 to 35 years. So you can use tank containers over and over again, giving you great value for money in the long run!

ISO certification: A stamp of approval for ISO tank

So what is an ISO certification?

The International Organization for Standardization (ISO) upholds a set of industrial and commercial standards for various products and services. This ensures consistency in both quality and reliability.

When a tank container is manufactured, it must comply with the size, durability, and strength as per the ISO standards. Each tank goes through strict inspection process, and only then is it certified. A container safety certificate (CSC) is also issued by the manufacturer.

Never overfill or underfill a tank container

It’s important to note that a tank container should never be overfilled or underfilled.

ISO tanks should be at least 80% full at all times. This will avoid a surge during transit.

Similarly, always make sure that your tanks are less than 95% full. This allows for thermal expansion.
