About Diplom-Is
Diplom-Is is Norway's leading ice cream supplier, based in Nittedal and wholly owned by TINE, which lists it as acquired in 1991. It had record ice cream sales in the summer of 2025, and that autumn it stopped delivering to shops with its own fleet and moved to wholesale distribution, a change planned for several years that let it sell off its delivery vehicles.
