At National Commodity and Derivatives Exchange, sugar for delivery in October declined by Rs 8, or 0.34 per cent, to Rs 2,340 per quintal with an open interest of 52,980 lots.
Similarly, the sweetener for delivery in December shed Rs 5, or 0.21 per cent, to Rs 2,365 per quintal in 37,240 lots.
Analysts said offloading of positions by traders, triggered by higher supplies from mills in the physical market against low demand from bulk consumers, kept sugar prices down at futures trade.
