Russians from Moscow may try another official way (though it is difficult):

In short, if you have got status of juridical entity in Russia, you may get "FSS approvement" for individual shipment.

Thanks on the tips. Unless the carrier service can guarantee good passage to Russia, we will not proceed. The Pinebook has very thin profit margin, especially recently the Flash and DRAM price jack up crazily, and we cannot afford to keep subsidize the "unsure" shipping cost.
