This scheme is actual for any type of goods export. This is the most comon use of offshore companies.
At the beginning, we don't use any tax optimization schemes and company pays revenue taxes in Russian Federation. I.e. foreign buyer pays 600 units to Russian company. The Russian company pays to supplier 500 units. As result of such operations, the Russina company gets revenue 100 units, but it has to pay revenue taxes, which is 24% and finally it gets 76 units as revenue.
You can see a scheme describing tex optimizations as follows:
|0%=0||Tax on revenue|
|60||Revenue after taxation|
