March 18th News: On March 18th, Changzhou Xinyang's phthalic anhydride plant, with a capacity of 100,000 tons, operated at less than 50% utilization. The manufacturer reported low inventory levels and quoted phthalic anhydride at 8,700 yuan/ton, representing an increase of 150 yuan/ton. Chempricehub's analysis of phthalic anhydride gave a long-short score of 1.5. The operation rate of Changzhou Xinyang's phthalic anhydride plant being below 50% indicates a reduction in supply, while low inventory levels reflect relatively strong demand or a supply shortage. The price increase of 150 yuan/ton to 8,700 yuan/ton directly demonstrates tight supply and demand in the spot market, driving prices upward. This constitutes a strong positive factor, and it is expected that the spot price of phthalic anhydride may continue to rise in the short term.
