Today's phthalic anhydride spot market analysis shows that the current phthalic anhydride price is in a fluctuating stage, with the average difference indicator pointing to a mild correction (bearish) attribute. The price has already reached a high range within the past 1-year cycle, and the room for further increase is limited. Industry chain participants can focus on the price fluctuations of upstream OX and refined naphthalene raw materials, as well as the changes in procurement demand in the downstream unsaturated resins and plasticizers sectors.
Data Explanation

6. Fundamental Reference
On September 14, the mainstream phthalic anhydride manufacturers in China raised their quotes by 200 CNY/ton. The production facilities of Tongling Chemical and Shijiazhuang Bailong Chemical are operating normally, with tight supply and low inventory, leading to a synchronized increase in actual transaction prices. Phthalic anhydride's upstream materials are naphthalene and OX, while its downstream applications cover herbicides, unsaturated resins, and plasticizers such as DOP/DBP/DINP.
