Intermediate bulk containers (also known as IBC tank, IBC tote, IBC, or pallet tank) are industrial-grade containers engineered for the mass handling, transport, and storage of liquids, semi-solids, pastes, or solids. The two main categories of IBC tanks are flexible IBCs and rigid IBCs. Many IBCs are reused or repurposed. Description Rigid IBC tanks 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 to be fabricated of a volume up to while maintaining the "IBC" name and their federal shipping and handling permits. IBC tank capacities generally used are often . 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. 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. Flexible IBC tanks A standard flexible intermediate bulk container can hold and manufacturers offer bags with a volume of . In addition to the above materials, flexible IBCs can also be made of fiberboard, wood, aluminum, and folding plastic. Folding IBCs are also made of heavy plastic. Their sides fold inward when the unit is empty allowing the IBC to collapse into a much smaller package for return
