Supported by the firm international urea market and increased buying demand, the price of standard caprolactam grade ammonium sulphate is at $140-145/ton FOB. Most suppliers offer cargoes at $140-145/ton FOB and have no inventory pressure. Several caprolactam enterprises plan to carry out maintenance in April-May, which may tighten overall supply. More inquiries were also received from India, Egypt and Latin America this week. Due to the bullish sentiment in the urea market, increased inquiries from Brazilian importers and firm raw material prices, the price of extruded pellets has risen to $150-162/ton FOB. But some Brazilian importers are still waiting and have not started large-scale purchases. It is reported that 6,000-8,000 tons of extruded pellets that may be shipped to Brazil at the end of April were traded at $150-155/ton FOB. A river supplier sold a small amount of 2,000 tons of extruded pellets at about $175/ton cfr for April shipment, but did not specify the destination.
