KUALA LUMPUR: Malaysia kept its export duty on crude palm oil for May at 0%, according to a circular on the Malaysian Palm Oil Board's website on Wednesday that cited the national customs department.

The duty has been at 0% since September.

Malaysia, the world's second-largest producer of palm oil, calculated a palm oil reference price of RM1,981.03 (US$479.32) per tonne for May. Any price above RM2,250 incurs a duty.

Malaysian benchmark palm oil futures rose 1.6% to RM2,207 a tonne on Wednesday, after earlier reaching a one-week top of RM2,219.
