The tax, which may come in form of a cess, will kick in the moment oil prices cross USD 70 per barrel, sources privy to the development said.



Under the scheme, oil producers, who get paid international rates for the oil they produce from domestic fields, would have to part with any revenue they earn from prices crossing USD 70 per barrel mark.

Petrol and diesel prices were raised for the 11th day in succession today as the state-owned oil firms gradually passed on to the consumer the increased cost of international oil that had accumulated since a 19-day freeze was imposed just before Karnataka elections.
