At the same time, a road development cess of 50 paise a litre has been imposed on petrol and diesel.

"The proposed changes are revenue neutral and I have been assured that there will be no increase in the retail prices of these products as a result of the changes in the duty structure," he said in his Budget speech.

The reduction in duties on domestic cooking gas (LPG) and kerosene for public distribution system will help oil companies contain their losses they were incurring because of not being allowed to change retail prices in line with the change in prices of raw materials.

Besides, the government has left subsidies on domestic LPG and Kerosene unchanged. Customs duty on crude oil has been halved to 5 per cent while that on kerosene for public distribution system and LPG for domestic use has been slashed from 5 per cent to nil.

Excise duty on the two has also been brought down to nil, from 12 per cent (Kerosene) and 8 per cent (LPG) respectively.

Import duty on petrol and diesel has also been reduced from 15 per cent to 10 per cent each while on the excise duty front, the government, with a view to check the impact of the volatility in international oil prices, moved from ad valorem duty structure on petrol and diesel to a combination of lower ad valorem duty plus specific duty.
