The Directorate General of Foreign Trade (DGFT) in a notification said that "export of potatoes is permitted subject to MEP of USD 450 per tonne".
The MEP comes into immediate effect, it said.
As part of government's effort to rein in food prices, Finance Minister Arun Jaitley had announced government would impose export curbs in form of higher MEP on onion and potatoes.
While the MEP on onion of USD 300 per tonne was notified on June 17, the same on potatoes was announced today.
Rising prices of essential food items like vegetables, fruits and cereals pushed up wholesale price index based inflation to five-month high of 6.01 per cent in May.
