Before expanding further, here are three of the most commonly used ways to transport liquids securely and safely:
Drums and barrels: Available in fiber, plastic, and steel, drums and barrels have always been the standard choice for liquid cargo weighing 5 to 60 gallons. If you are planning to load liquid consumables, drum containers require a coating or liner. Securing them with pallets and strapping are essential for their stability and safety, respectively.
ISO tank containers: Following the standards set by International Organization for Standardization (ISO), this container has a length of 20 feet and a cubic capacity from 5,200 gallons up to 6,800 gallons. Made of anti-corrosive material and robust steel, this is the safest option for transporting large quantities of liquid material.
IBC containers: Intermediate bulk containers, or IBC, fall between drums and ISO tank containers. These vessels can accommodate a capacity between 53 to 1,250 gallons. IBC is a common choice for transporting hazardous materials because of its superior stability due to the galvanized steel frame around the barrel. In addition, these containers have both top and bottom discharge/loading points.
Flexitanks fall under the same category as the ISO tank containers. However, flexitank is the better option for non-hazardous liquids. It is also more cost-effective since it does not require special machinery for loading and unloading liquid cargo.
