A Complete Guide to ISO Containers

It’s estimated that over 20 million cargo containers are on the move at any given time. You can find shipping containers everywhere, from their original purpose on ships and in ports to being repurposed as extra storage or accommodation on construction sites. Because of their long shelf life and durability, they are easily repurposed. 

Their initial use for transporting goods efficiently and effectively worldwide through multi-modal channels led to the introduction of a globally accepted shipping container standard. Shipping containers must comply with the International Organisation for Standardisation (ISO) container standards. 

Whether you want to buy a new container or a refurbished one, Cabin Solutions can help you find top-quality ISO storage containers in the UK. In today’s blog, we’ll learn about ISO container standards. Let’s get started.

What Is an ISO Container?

ISO containers are cargo containers used to transport goods via roads or waterways through trucks, cargo ships or trains. ISO is the acronym for International Organisation for Standardisation, a global organisation that sets the standards or benchmarks to which shipping containers must adhere. 

ISO storage containers were patented in the 1960s when the organisation established the rules for freight containers to facilitate the safe transportation of goods. No matter where they are manufactured or for what purpose they are used, ISO container standards regarding strength, measurements, and ability to withstand harsh weather conditions must be complied with.

There are several types of ISO storage containers:

• Dry containers
• Refrigerated containers
• Tanks containers
• Open top containers
• Open side containers
• High cube containers
• Flat rack containers
• Tunnel containers
• Special purpose (customised) containers

ISO Storage Container Standards

ISO container standards apply to every aspect of a freight container, from its overall dimensions to its stackability, the twist locks used to fasten it, and even the terminology used to describe it.

Some common ISO container codes used in the industry are:

ISO 668:2020 – Container Dimensions and Design Requirements

This shipping container standard concerns the container’s dimensions, internal and external measurements, weight, and door mechanism. It’s designed to ensure container uniformity, making it easy to stack or fit them on ships, trucks, or trains.

ISO 1496 – Structural Strength and Durability

Cargo containers are used to transport various things, from metals to chemicals and cars. This shipping container standard ensures that the container is strong and durable enough to withstand the cargo load and transport stress. The ISO container code allows for quick specification identification and this is obtained only when certain standards are met. A container must undergo rigorous testing for structural integrity, transport stress (being lifted by forklift and stacked) and ability to withstand harsh weather conditions to become regulated.

ISO 6346 – Container Identification

This ISO container standard requires each container to be identifiable to facilitate tracking and management throughout its lifecycle. Every container must display the category identifier and serial number, as well as a check digit.

Benefits of an ISO Container

Let’s look at the advantages of using ISO storage containers:

Reduced Cost

Using a container that adheres to ISO standards helps uniformise the freight and transport industry. For example, if you use ISO storage containers, they’re all of the same size and can be easily stacked and transported. However, a non-compliant container won’t easily fit in the allocated space, and transporters will charge you more for the transit.

Extended Lifespan

To achieve ISO container standards, the containers undergo extensive testing for strength and durability. When you buy these containers, you’ll be guaranteed their longevity and can easily calculate your return on investment (ROI). ISO containers are made of COR-TEN steel, which is known to be extremely weather-resistant and strong.

Versatile Usage

The features of ISO containers make them highly versatile and flexible. They can be used not only to transport goods but also as food trucks, pop-up restaurants or even on-site accommodation. 

Safety 

ISO storage containers are fitted with industrial-grade locking mechanisms,  are leak-proof and have proper ventilation, making it easy to transport goods of different kinds safely across the world.

How to Identify ISO Container

So, how do you identify if the container you want to purchase complies with the ISO container standard?

Here are some important identification marks to look out for:

1. The BIC (Bureau International des Containers) code consists of four letters, helping to identify the owner and the purpose of the container. It’s found in the upper right corner of the container.
2. The BIC code precedes the unique six-digit serial number, which helps in easy tracking and identification.
3. The check digit is a one-digit number enclosed in a small box that helps verify the information’s authenticity.
4. A four-digit code is found on the container and signifies the dimension and type of the container.
5. The side of the container contains operational details such as payload capacity, maximum gross mass, and tare weight.
