It seems to me I've reported smth like this already, but today SovFed (upper chamber of State Duma) has officially permitted 10K EUR (and 50 kg) upper limit for personally imported goods if carried in by air transport to Customs Union (Belorussia, Russian Federation, Kazakhstan): - in Russian

All exceeding of 50 kg is subject of 30% customs taxes, but not less than 4 EUR/kg.

3L of alcohol is tax free, 2L extra is permitted, but taxed.
200 cigarettes, or 250g of tobacco, or 50 cigars are tax free.

For car, sea or railway transport the limit is still 1.5K EUR.
