To my knowledge, grain export was not a major contributor to the first famine, especially since the Allied blockade wasn’t even lifted until the famine was already underway. Even as late as 1923 Soviet imports of food was considerable (and much of the remainder being consumer goods and raw materials, not industrial machinery) with industrialization not being emphasized until the 14th Party Congress in late 1925.
