The resolution posted on the Web site of the Russian government says that the tax takes effect from Sept. 1, 2012.
The document does not mention any special regime for supplies from Ukraine.
Ukrainian experts says that the introduction of the tax at the first
stage could fully stop supplies of vehicles from Ukraine to Russia, of
both trucks and buses and passenger cars, which today are shipped
without additional fees under a free trade agreement. Additional
payments for trucks are assessed at up to $27,000, for a large bus – up
to $20,000-22,000 and for a passenger car – up to $500-1,000.
