Rigid intermediate bulk containers are stackable, reusable, versatile containers with an integrated pallet base mount that provides forklift and/or pallet jack maneuverability. These containers can be made from metal, plastic, or a composite construction of the two materials. Rigid IBC design types are manufactured across a volume range that is in between that of standard shipping drums and intermodal tank containers, hence the title "intermediate“ bulk container. IBC totes are authorized per Title 49 CFR codes[3] to be fabricated of volume from 110 gallons up to 793 gallons while maintaining the "IBC" name and their federal shipping and handling permits.
IBC tank capacities generally used are often 275 and 330 US gallons (229 and 275 imp gal; 1,040 and 1,250 L).[4]Intermediate bulk containers are standardized shipping containers often UN/DOT certified for the transport handling of hazardous and non-hazardous, packing group II and packing group III commodities. Many IBC totes are manufactured according to federal and NSF/ANSI regulations and mandates, and are often IMDG approved as well for domestic and maritime transport. Metal alloy IBC tanks are also manufactured according to NFPA and UL142 certification standards for extensive storage of materials labeled as flammable and/or combustible.[5]
Intermediate bulk containers can be manufactured from various materials based on the requirements of the application or service the IBC will be used for. Traditional materials include:
Plastic (high-density polyethylene)
Composite: galvanized steel and plastic
Carbon steel
Stainless steel (304 and 316/316L grades)
The most widely utilized and known IBC is the limited re-use, caged IBC tote container. Caged IBC totes are composite intermediate bulk containers — a white/translucent plastic container (typically high-density polyethylene) contained and protected by a tubular galvanized steel grid, common. Caged IBC totes are commonly used due to their low cost, wide compatibility, and versatility.
