March 13th News: On March 13th, Changzhou Xinyang's phthalic anhydride plant, with a capacity of 100,000 tons, is operating at less than 50% utilization. The manufacturer's inventory is low, and the phthalic anhydride price is quoted at 8,350 yuan per ton, representing an increase of 450 yuan per ton. Chempricehub's analysis of phthalic anhydride, with a bullish-bearish score of 2, indicates that Changzhou Xinyang's phthalic anhydride plant operating at less than 50% utilization suggests supply constraints; low inventory further exacerbates supply tightness; the price increase of 450 yuan per ton to 8,350 yuan per ton demonstrates strong upward price momentum. These factors combined are expected to have a significant positive impact on the spot price of phthalic anhydride, with short-term prices likely to continue rising.
