This daily report is based on phthalic anhydride price data, major manufacturer quotes, and industry chain information up to September 13, 2026. The current spot price of phthalic anhydride in China is at a near one-year high. The signal from the average difference indicates that the market is in a strong consolidation (bullish) pattern. The tight supply from the upstream sector supports the strong price trend, but the room for further increases at these high levels is relatively limited.

6. Physical Market Fundamentals Update
Recently, the operations of major phthalic anhydride manufacturers in China have been generally stable, but inventories are generally low, and the supply is clearly tight: since September, the phthalic anhydride price of Tongling Chemical Industry Group has cumulatively increased by 200 CNY/ton, with the current quotation at 10,000 CNY/ton, and sales are limited; Shijiazhuang Bailong Chemical's phthalic anhydride quotation is 10,000 CNY/ton, with limited inventory mainly for internal use; Changzhou Xinyang's phthalic anhydride facility utilization rate is around 60%, with low inventory, limited orders, and sometimes no quotations, the upward quotations from the manufacturers provide strong support to the spot prices.
VII. Overview of the Industrial Chain
Phthalic anhydride's core raw materials upstream are refined naphthalene and OX; downstream, it covers agricultural chemical categories such as bentazon, phthalate plasticizers, unsaturated resins, alkyd resins, and other chemical products. The overall stable demand downstream provides a bottom support for the price.
