Overview
Outdoor chemical storage in a bunded container
Bunded chemical storage shipping containers are outdoor steel stores with an integrated leak-tight bund, a chemical-resistant internal finish, and high and low ventilation, built to hold flammable, corrosive, or toxic chemicals safely. SCS Global makes them factory-direct in 10ft, 20ft, 20ft side-opening, and large-sump builds, each compliant with AS 1940:2017 and AS 3780:2023. Many buyers search for chemical storage without knowing their goods are classified dangerous goods: if you store solvents, acids, oxidisers, or agricultural chemistry, those goods almost certainly fall under a dangerous goods class, and a bunded container is the compliant answer. Every unit is part of our range of dangerous goods containers and ships with a Certificate of Compliance. The bund is a welded steel floor that captures the full contents of a spill or leak below the working floor, so nothing reaches the ground or the stormwater system. SCS builds factory-direct from Yixing, Jiangsu, then ships each unit ready-signed and AS-compliant.
Specifications
Bunded Chemical Store Capability
Every bunded chemical store carries the same core capability set, scaled to size. The bund is integrated into the welded floor frame, the lining is matched to the chemistry, and ventilation disperses vapour, all sized to the chemicals the unit will hold rather than fixed at one figure.
| Specification | Value |
|---|---|
| Secondary containment (bund / sump) | Integrated welded steel bund, 100% leak containment. SCS design 800 L (10ft), 1,200 L (20ft), large-capacity builds to 5,000 L. Volume governed by AS 1940 and AS 3780, sized to the chemicals stored. |
| Floor | Fully welded steel floor on an RHS frame, with a non-spark mesh floor covering (no timber) over the integrated bund. |
| Internal lining | Chemical-resistant internal finish. Thermoplastic or polyethylene lining meets the AS 3780 chemical-resistant-finish requirement for Class 8 corrosives. |

Australia
Chemical Storage Containers in Australia
In Australia, chemical storage in a bunded DG container is governed by AS 1940, AS 3780, and AS 3833:2024, and discharges the operator's WHS dangerous-goods duties under the state regulator. The controlling standards are Australian, so chemical storage containers in Australia are specified against those documents rather than overseas codes. SCS ships factory-direct, delivered DDP to your nearest port, so the unit arrives built, signed, and certified, with one supplier covering build, shipping, and compliance documentation. New Zealand runs the separate HSNO regime, so assess NZ deployments against HSNO instead.
Sizes
Container Sizes and Configurations
SCS builds bunded chemical stores in 10ft, 20ft, 20ft side-opening, and 40ft or large-sump configurations, with bund capacity from 800 L to 5,000 L. The 10ft (2,840 mm internal, 800 L bund) is one of the more portable chemical storage containers for tight worksites, depots, and laboratories. The 20ft (5,900 mm internal, 1,200 L bund) and the side-opening build add full-bay forklift access, while the 40ft and large-sump builds answer the brief for large chemical storage containers holding bulk drum and IBC inventory. The size spokes carry full dimensional tables.
Platform
Chemical Storage Shipping Containers
A shipping-container platform makes a sound chemical store: a fully welded Corten steel shell, ISO corner castings, forklift pockets, and crane lugs make it relocatable and site-ready. Chemical storage shipping containers start from a structure already rated for stacking, craning, and sea transport, so the box tolerates rough handling a purpose-built fixed bund store is not designed for. When the site moves, the store moves with it, craned into place with no demolition. A container-derived build also lands at lower cost and shorter lead time than fixed infrastructure.
Compliance
Hazardous Chemical Storage Compliance
Which standard governs a chemical store depends on the goods: AS 1940 for flammable and combustible liquids, AS 3780 for corrosives, and AS 3833:2024 where incompatible classes are stored together. Hazardous chemical containers are not specified by container size alone, but by the class of chemistry inside them. Map your inventory to its class first, and the controlling standard follows: flammable solvents and fuels to Class 3, acids and alkalis to Class 8, oxidisers to Class 5.1, toxics to Class 6.1, and any mixed inventory to the segregation rules of AS 3833:2024. SCS supplies hazardous chemical storage containers built to the standard that matches your register, with a Certificate of Compliance and third-party inspection on each unit.

Frequently Asked Questions
Three questions procurement and HSE teams ask most often about bunded chemical storage containers.
What is chemical storage?
Chemical storage is the controlled holding of hazardous chemicals in a way that contains spills, manages vapour, and separates incompatible substances. For outdoor or bulk volumes, that means a bunded, ventilated steel store built to AS 1940 and AS 3780, sized to the chemicals held and supplied with a Certificate of Compliance.
What chemicals require bunded storage?
Flammable and combustible liquids, corrosive acids and bases, oxidisers, toxics, and most working chemistry held in drums or IBCs require secondary containment under AS 1940 or AS 3780. If a spill could reach the ground or the stormwater system, the store needs a bund sized to the chemicals held.
What is the difference between a chemical storage cabinet and a chemical storage container?
A cabinet is an indoor, small-volume unit for litres of chemistry inside a building. A chemical storage container is an outdoor, bulk, relocatable steel store for drums and IBCs, with an integrated bund and AS-compliant ventilation. Choose a container for outdoor bulk storage and a cabinet for small indoor quantities.
