The NCDEX has marked 2,160 tonne of coriander for staggered delivery in the June contract. The bourse has also marked 1,530 tonne of soybean, 260 tonne of cottonseed oilcake, 240 tonne each of castor seed and guar seed, 200 tonne of guar gum, 195 tonne turmeric, 170 tonne of barley and 78 tonne of jeera staggered delivery. Staggered delivery is used to check any artificial rise in prices. Under this mechanism, sellers can indicate intention of delivery to the exchange during the tender period, currently a 10-day span before the contract expires.
