Re-export of raw materials exempted from export tax is prohibited. After the establishment of the common market for oil and petroleum products, EAEU member states will have to give up their regulation of internal prices for petroleum products (which remain in effect in Belarus and Kazakhstan) and unify export taxes for oil and petroleum products outside the EAEU (or even cancel them). The Russian Federation does not levy export tax on oil and petroleum products supplied to Belarus, but Belarus levies an export tax when selling refined petroleum products made from Russian raw materials to countries outside the EAEU. The Russian Federation thus insisted on the harmonisation of Belarus’ export taxes on energy with its own.
