What are ISO containers?

ISO containers are standardised steel shipping containers built to the specifications set by the International Organisation for Standardisation. These types of containers are used globally for the transport and storage of goods, and also for portable cabin and conversion applications.

What is the difference between ISO and non-ISO containers?

ISO containers conform to internationally recognised standards for size, structure and markings, making them approved for global shipping. Non-ISO containers are those that have been cut down or significantly modified so no longer meet these standards. Because of this, they can’t be used for international transit, but can be used for static or on-site applications.

Do I need planning permission for an ISO container?

In many cases, temporary placement of an ISO container does not require planning permission, particularly on commercial or industrial sites. However, it depends on factors including the intended use, duration, and local planning authority. We recommend checking with your local council before installation.

What are the ISO standards?

The three core standards governing ISO shipping containers are: ISO 668:2020 (dimensions and design)ISO 1496 (structural strength and durability)ISO 6346 (identification and marking) Together, these ensure that every container is safe, robust and traceable throughout its working life.

What is an ISO Shipping Container?

ISO shipping containers are used to transport and store a variety of goods, with standards for their dimensions being 8ft wide, 8ft 6” high and either 10ft, 20ft or 40ft in length.

The uniformity in dimensions benefits logistics and transportation, allowing for containers to be easily stacked on top of each other during shipping via road and sea.

ISO shipping containers have found new uses beyond storage.

Shipping container conversions transform ISO containers into a wide range of applications, including office spaces, pop-up shops, workshops and living accommodations, providing a much faster and cost-effective solution for those requiring new spaces.

Benefit of ISO Containers

Durable

Built to withstand harsh conditions at sea and on land, ISO containers are made from high-strength steel and reinforced corner castings. This robustness ensures they resist weather, impact and heavy loads, providing secure and long-lasting storage or transport for goods, or even converted spaces.

Versatile

An ISO shipping container can be modified and converted for countless applications. They can be used as container housing, offices, cafes, container workshops and much more. Their height can also increase to become high cube containers, as well as feature different door designs for specific access requirements.

Use Cases for ISO containers

ISO shipping containers for sale come in standard dimensions, with options for 10ft shipping containers, ideal for storage and extensions, and 20ft shipping containers, which are ideal for conversions as well as long-haul and high-volume shipping.

No matter the length you choose, ISO containers are ideal for shipping and logistics, providing secure, stackable transport for goods of all sizes.

Even awkward, tall and bulky items can be stored thanks to high cube containers featuring an extra foot in height while still built to ISO standard widths and lengths.

ISO shipping containers are becoming increasingly popular for conversions into portable offices, workshops or retail units, offering flexible and cost-effective spaces.

They can also be adapted to feature different cladding, finishes and colours, perfect for specific settings requiring professional aesthetics.

Insulated shipping containers are also available, ready to be fitted out for a range of purposes.

ISO Container Standards

ISO container standards form the backbone of the global shipping industry, ensuring every container that arrives on your site meets strict safety requirements.

ISO 668:2020 (Dimensions and Design)

This standard defines the external and internal dimensions, door clearances and maximum gross weights for all ISO shipping containers. For the end user, it gives peace of mind that their container will fit onto any vehicle or vessel with no issues.

ISO 1496 (Strength and Durability)

ISO 1496 sets the structural performance requirements that every container must pass before it can be certified for use. For the end user, this means confidence that your container will remain safe and secure under real-world working conditions.

ISO 6346 (Identification and Marking)

Every ISO container must carry a standardised identification code, making it traceable across its operational life. For businesses operating across multiple sites or supply chains, this simplifies container management.

Non-ISO Containers

Not all containers on the market are ISO compliant. A container is classified as non-ISO when it no longer conforms to the dimension, structural or marking standards set out above.

This most commonly happens when a container has been modified with new openings for windows and doors, or the size is cut down.

That said, non-ISO containers are still perfectly usable in many applications, including for storage, site accommodation and static conversions. ISO certification isn’t always a practical requirement.
