Food-grade IBCs for edible oils must meet UN and food contact material standards. The key specification is: UN 31HA1/Y (HDPE composite IBC with metal cage, rated for hazardous and non-hazardous food liquids). All IBCs supplied for food use should carry UN certification markings embossed on the container.
Food contact compliance: The HDPE inner bottle must be certified food-contact compliant under EU Regulation 10/2011 (plastic food contact materials) or equivalent national standard. Request a Declaration of Compliance (DoC) from the IBC supplier confirming the container is food-contact approved for edible oil use.
Reconditioning and reuse: Food-grade composite IBCs (caged plastic IBCs) are typically reconditioned and reused multiple times. Reconditioned IBCs must be properly inspected, cleaned, and leak-tested before refilling with food products. Ask whether the IBCs supplied are new or reconditioned — for food-grade edible oil, reconditioned IBCs are acceptable if certified for food use, inspected, and sourced from a reputable reconditioner. New IBCs are preferable for initial use or where a rigorous food safety management system requires new packaging.
Solid oil handling in IBCs: For palm oil, coconut oil, or PKO supplied in IBCs in cooler climates, the oil will solidify at low ambient temperature. IBCs for solid oils require heated storage or heated discharge — electric IBC heating jackets or steam-heated rooms are the standard approaches. Confirm heated storage infrastructure at your facility before ordering solid-fraction oils in IBC format.
Filling and labelling standards: Each IBC should be labelled with: oil type and grade, lot number, production date, best-before date, net weight (tared IBC weight vs gross weight), supplier name and country of origin, food-contact compliant sticker, and Halal/organic certification markings if applicable.
Number of IBCs per 20ft container: A standard 20ft container typically holds 5–6 × 1,000-litre IBCs (the exact number depends on IBC external dimensions — most standard composite IBCs are 1,200mm × 1,000mm footprint × 1,165mm height, fitting 5 per container 20ft). A 40ft container holds 10–12 IBCs. Some buyers use 600-litre or 800-litre IBCs for specific applications — confirm with your supplier.
