Prices of sugar rose in the key wholesale markets of Muzaffarnagar and Mumbai, as demand for the sweetener improved at low prices, and as Stuckists sought to replenish inventories at the start of the month. In Muzaffarnagar and Delhi, sugar was sold up 10 rupees from previous close. In Mumbai, sugar was sold up 5 rupees from Monday. In Maharashtra, where prices had fallen for the last one week, demand also rose due to buying at lower price levels. In north India, soaring prices are unlikely to sustain due to record high sugar output in Uttar Pradesh. Mills across Uttar Pradesh produced 8.70 million tonne of sugar during Oct 1-May 1, up 28% from a year ago. The government had on Apr 5 allowed duty-free import of 500,000 tonne of raw sugar under the tariff rate quota. The most-active May contract was up 0.2%.
