At the National Commodity and Derivatives Exchange, sugar for delivery in December declined by Rs 34, or 0.98 per cent, to Rs 3,425 per quintal with an open interest of 1,930 lots.
On similar lines, the sweetener for delivery in March contract traded lower by Rs 15, or 0.41 per cent to Rs 3,615 per quintal in 4,710 lots.
Analysts said trimming of positions by traders, amid sufficient stocks on increased supplies from mills in the physical market against lower demand from bulk consumers, mainly led to the fall in sugar prices at futures trade.
