What is an ISO tank?
An ISO tank is a container that is built to the ISO (International Organization for Standardization) stands and designed to carry hazardous and non-hazardous bulk liquids.
ISO tanks offer a safe, reliable, and cost-effective transportation package for moving bulk liquids around the world. Easier to handle, more robust, and safer than drums, totes, and flexibags.
ISO Tanks are ideal for:
A lower cost intermodal solution to replace long haul truck movements and reduce your carbon footprint.
Combat capacity restraints in the truck tank market.
Intermodal solutions that include marine shipping.
When maintaining high purity is an issue (tanks move from manufacturer to customer without any transfers).
When storage is required — ISO tanks can be stacked and they are much less expensive to keep onsite than tanker trucks.
