There are both smaller and larger tank containers, which usually have a size different from the ISO standard sizes. For example, there are some 27,000 liters (5,900 imp gal; 7,100 U.S. gal) and above litre tank containers in the European swap body fleets in Europe but they are not used on international business only on intra European traffic.
