This issue of the phthalic anhydride price market daily report is based on the latest spot data as of August 26, 2026. The analysis using the mean difference method shows that the current phthalic anhydride prices are in a deep correction phase, with the overall trend being volatile and bearish. Prices are at a high level over the past year, with limited room for increase. Most phthalic anhydride manufacturers in China are operating with low inventory and limited order acceptance. Subsequent attention should be paid to the supply of upstream raw materials and changes in demand from the downstream plasticizers and resins industries.
