What is an IBC container? It is an industrial package designed to store and move liquids in larger volumes than a drum can usually handle. Warehouses, manufacturers and distribution sites use IBCs for products ranging from food ingredients to chemicals and oils. This guide explains how the common types are constructed, the capacities available and the practical points to consider when storing them, including spill control, physical protection and temperature exposure.

What is an IBC container?
IBC stands for intermediate bulk container. It is a transport and storage package for liquids, designed to hold more than a drum while remaining suitable for mechanical handling. The term IBC tank is also commonly used in industry.
A common composite IBC has a rigid inner container, often made from high-density polyethylene (HDPE), within a protective metal cage. The cage sits on a pallet base so the unit can be moved using suitable handling equipment. A filling opening is usually located at the top, with a discharge valve near the bottom.
Not every IBC has the same construction. Materials, cage design, base type and fittings can vary, so check that the container is suitable for its contents and intended use. The product’s label and technical information should guide decisions about compatibility, handling and storage.
Common IBC sizes and capacities
The capacity of an IBC is the volume it is designed to hold. A 1,000-litre IBC is the most common size, while smaller and larger options are available for different processes and site requirements.
| Capacity | Typical consideration |
|---|---|
| 600 litres | A smaller-volume option where lower quantities or site constraints matter |
| 1,000 litres | A widely used capacity for industrial liquid storage and handling |
| Around 1,250 litres | A larger-volume option where the process and handling equipment allow |
Capacity does not tell you the exact footprint or height of a container. Dimensions vary by design, and the full weight depends on the IBC and the liquid inside. Confirm dimensions, tare weight, filled weight and handling requirements before planning a storage area.
Types of IBC
Caged rigid IBCs are commonly used for industrial liquids. In a composite design, a rigid inner container sits inside a protective outer cage. Some designs use different materials or construction, so check the product specification for the application.
Flexible IBCs, often called bulk bags, are generally used for dry bulk materials rather than liquids. They are a different type of package and should not be treated as interchangeable with rigid liquid containers.
IBCs may be supplied new, rebottled or reconditioned. The container’s condition, previous use and cleaning history matter, especially when it will hold food ingredients or a substance that could react with residues. UN-rated IBCs are designed and tested for specified dangerous-goods transport requirements; check the rating and permitted use for the substance and route.
What are IBCs used for?
Food and drink manufacturers use IBCs for liquid ingredients such as syrups, concentrates and processing liquids. The container must be suitable for the product and meet the site’s hygiene and handling requirements.
Chemical and cleaning-product businesses use them for products that may need to be stored or transferred in larger volumes. Compatibility between the contents, the container and its fittings needs to be checked before use.
Solvents, oils and lubricants are also handled in IBCs. Their storage arrangements depend on the substance, site conditions and applicable requirements, including the controls needed to manage leaks or spills.
Agricultural businesses use IBCs for a range of liquid products. Whatever the sector, clear identification and a suitable storage plan help staff understand what each container holds and how it should be handled.
How to store IBCs safely
Safe storage involves more than finding enough floor space. The site should consider what could happen if an IBC leaks, is struck by handling equipment or is exposed to temperatures that could affect the contents or container.
Manage spill risk with secondary containment
Secondary containment is an additional barrier, such as a bund or suitable drip tray, intended to catch liquid if the main container leaks. Its design and capacity should be suitable for the substance, the number of containers and the site layout.
As a UK reference, GOV.UK’s pollution-prevention guidance for businesses recommends secondary containment of at least 110% of the capacity of storage containers over 205 litres. For multiple containers, capacity guidance also takes account of the combined volume and the largest container. Requirements can vary with the substance, storage arrangement and location, so check the rules that apply to the site.
A spill tray may be suitable for a specific IBC and storage arrangement. Sites should also consider whether spill kits are appropriate for the liquids handled and whether staff know how to respond to a spill.
Reduce the risk of physical damage
Position IBCs away from vehicle routes and other areas where they could be struck. Where traffic or handling activity creates a risk, consider whether barriers or a separate storage area are needed.
Inspect the container, cage, pallet base, valve and fittings as part of the site’s routine checks. Look for leaks, visible damage or loose components, and follow the site process for isolating or reporting a damaged container. Keep valves secured when they are not in use and make sure container labels remain readable.
Consider temperature and weather exposure
Cold conditions can change how a liquid flows. Some contents may thicken, crystallise or freeze, and freezing may damage fittings or valves depending on the product and container. Heat and direct sunlight can also affect some liquids and may increase exposure of the IBC bottle to UV.
Where temperature changes could affect the product, consider the storage location and whether additional protection is needed. An insulated cover can slow heat transfer, but it does not actively heat the container or guarantee that contents will not freeze.

Common questions about IBCs
How many litres is an IBC?
A 1,000-litre IBC is the most common capacity, but smaller options such as 600 litres and larger formats around 1,250 litres are also available.
What does IBC stand for?
IBC stands for intermediate bulk container.
Can IBCs be stored outside?
That depends on the contents, container, site conditions and storage controls. Consider exposure to temperature, sunlight, weather and physical damage, as well as the secondary containment required for the substance.
How long does an IBC last?
There is no single service life that applies to every IBC. Condition, previous use, contents, maintenance and the requirements of the particular application all matter. Follow the supplier’s guidance and your site’s inspection process.
