40ft Used High Cube Shipping Containers
40ft used high cube shipping containers are ISO-built steel containers offering extra internal height and large storage capacity at a lower cost than new units. Supplied wind and watertight with a valid 12-month CSC, they are suitable for export shipping, long-term storage, and container conversion projects across the UK.
What Is a 40ft Used High Cube Shipping Container?
A 40ft used high cube shipping container is a standard ISO container that has previously been used in international transport and is then decommissioned from active service. Buyers comparing container types may also find it useful to read our 40ft Used High Cube Shipping Container for Sale: Price, Specs & Buying Guide, which explains the typical specifications, pricing, and buying considerations.
Buyers who are still weighing up condition, access, and budget can also read our How to Buy a 40ft Shipping Container guide for a step-by-step overview of what to check before ordering.
Compared to standard 40ft containers, high cube units provide:
an additional 1ft (300mm) of internal height
increased cubic capacity
improved usability for tall goods and container conversions
Once removed from shipping fleets, these containers are inspected and graded to ensure they remain structurally sound, wind and watertight, and suitable for secure storage.
Why Choose a Used High Cube Over a Standard 40ft Container?
If you have sufficient space, a 40ft high cube container often delivers the best value per cubic metre.
Key advantages include:
- More usable internal volume without increasing footprint. Buyers who need exact measurements can read our 40ft Shipping Container Dimensions UK guide for full internal and external specs
- Better suitability for conversion projects (offices, workshops, retail units)
- Lower purchase cost compared to new one-trip high cube containers
- Ideal for storing large or tall machinery, stock, and equipment
Where height matters, the high cube option is usually the smarter choice.
Condition & Appearance (Important)
Used high cube containers are sold for function and performance, not cosmetic perfection.
You should expect:
- Dents and surface wear
- Evidence of previous repairs
- Cosmetic marks from prior service
However, every unit supplied is:
- Structurally sound
- Secure
- Guaranteed wind and watertight
Cosmetic condition does not affect strength, weather resistance, or lifespan.
Used containers vary in age, repair history, and visual condition, so buyers comparing value should also read How Much Does a 40ft Shipping Container Cost in the UK? to understand how condition affects price.
Shipping Certification (CSC)
Our 40ft used high cube shipping containers are supplied with:
- A valid CSC for 12 months, suitable for export shipping
The CSC can be extended if required, subject to inspection, making these containers a flexible option for both shipping and static use.
Buyers planning export use should also understand payload limits and plated weights, which are explained in our 40ft Shipping Container Weight: Tare, Payload & Gross Explained guide.
