A finance ministry official said the base import price of crude palm oil had been cut to $417 a tonne from $433, while that of crude soybean oil had been reduced to $497 a tonne from $510. India fixes base prices to calculate customs duties to prevent the loss of revenue due to under-invoicing by importers. Traders pay import duties on base values irrespective of the prices paid for the oil. The government also reduced the prices of RBD (refined, bleached and deoderised) palm oil to $432 a tonne from $435, other palm oil to $425 from $434, crude palmolein to $418 from $440, RBD palmolein to $421 from $445 and other palmolein to $420 from $443. India imports 150,000-200,000 tonnes of crude palm oil every month.
