March 17th News: On March 17th, Changzhou Xinyang's phthalic anhydride plant, with a capacity of 100,000 tons, is operating at less than 50% utilization. The manufacturer maintains low inventory levels, and the quoted price for phthalic anhydride is 8,550 yuan per ton, representing an increase of 200 yuan per ton. Chempricehub's analysis of phthalic anhydride indicates a bullish-bearish score of 2. The operation rate of Changzhou Xinyang's phthalic anhydride plant is below 50%, leading to a significant reduction in supply under its 100,000-ton capacity. Coupled with low inventory levels, this exacerbates the tight supply situation in the market, resulting in a spot price increase of 200 yuan per ton to 8,550 yuan per ton. This contraction on the supply side directly drives up spot prices, reflecting strong bullish signals. It is expected that prices will maintain an upward trend in the short term.
