Indonesian authorities have been weighing up for months whether to cut the crude palm oil export levy, which has been at its highest level for five months in a row, hurting demand.
The tariff for export levy begins when prices are at $750 per tonne, with a $20 increase for every $50 rise in CPO.
The benchmark palm oil contract for July delivery on the Bursa Malaysia Derivatives Exchange ended down 19 ringgit, or 0.47%, at 4,042 ringgit ($981.07) a tonne, after rising 5% on Monday.
Indonesia's crude palm oil output is estimated at 48.4 million tonnes while crude palm kernel oil (CPKO) is expected to be at 7.29 million tonnes this year, IOPRI said.
The benchmark palm oil contract for June delivery on the Bursa Malaysia Derivatives Exchange slipped by 2 ringgit, or 0.05%, to 3,739 ringgit ($903.58) a tonne after rising as much as 1% earlier in the day. For the week, it was up 1.3%.
