September 17 news
According to the SpotCom AI assistant, on September 16, 2026, the spot quotes for maleic anhydride in the main production areas of China remained stable, with no significant adjustments in the quotations from major factories. Based on the average difference analysis, the current maleic anhydride prices are in a strong consolidation (bullish) state, at a high level within the nearly 1-year cycle. In the short term, attention should be paid to the price fluctuations of upstream raw materials such as pure benzene and liquefied gas, as well as the demand release for downstream products such as unsaturated resins and tetrahydrofuran.
