The decision has come in the wake of the recently revised diesel prices, negatively impacting the cost of operations of the vast network of ground vehicles across the country, the company said in a press release issued here.
A greater impact is also being felt on air express operations with crude oil prices moving up by more than 30 per cent this year, the company said.
Price hike expected in ground is around 10-15 per cent while on air, price is expected to rise by 15-20 per cent.
