"It is available to any Indian airline, in other words, to all Indian airlines," it said.

As per the 1994 notification, the duty exemption is given when the quantity of the fuel is equal to the quantity of the same type of fuel which was taken out of India in the tanks.

Also, the rate of duty of customs or Central Excise leviable on such fuel should be same at the time of the arrivals and departures of such aircraft.
