Russia may reduce its export duty on most crude shipments by 7.4 percent on Oct. 1, after oil prices fell.
The standard duty may decline to $411.40 a ton ($56.12 a barrel) from $444.10 in September, according to Bloomberg calculations using a tax rate of 60 percent, down from 65 percent. The discounted rate on some eastern Siberian and Caspian Sea oil may be reduced to $204.50 from $205.10 this month.
The product duty may be set at $271.50 a ton next month. That would cut the tax on middle distillates such as diesel by 8.7 percent, while raising the rate for heavy products like fuel oil by 31 percent. A special gasoline tax imposed starting May 1 to fight domestic shortages may fall to $370.20 a ton.
