The first country where Sisus were exported was Estonia, where SAT sold the first SH-2 chassis in 1936. Due to the contemporary Estonian taxation system, complete vehicles could not be exported there, and therefore the cabins and superstructures were built locally. More units were sold in 1938. Latvia was the first country where complete Sisus were exported. The city of Riga bought a series of forward control buses powered by Hercules diesel engines which were delivered in 1937 and 1938. The complete number of vehicles exported to the Baltic states before the Second World War is not known but the business was regarded successful.
