A large range of transportable, fully compliant diesel tanks for the safe transportation of diesel fuel. Tanks over 450 litres or for multi site refuelling require a full ADR diesel approved tank or UN approved diesel tank. Tanks under 450 litres may be transported without full ADR or UN approval, if the person transporting the fuel is doing so for the main business and is using the fuel on one site. These diesel tanks are, according to ADR 1.1.3.1c, "approved for transport for immediate consumption". Another name for this is the "Craftsman's exemption".
