September 10th, it was reported that
According to the Spotcom AI assistant, the Chinese spot market for maleic anhydride has been continuously rising recently. Major factories in the main production areas of Jiangsu and Shandong have successively increased their ex-factory quotes. Based on the analysis using the average difference method, maleic anhydride has entered a clear upward trend. However, both short-term, medium-term, and long-term prices are at historically high levels, limiting further upward potential. The market needs to closely monitor fluctuations in the cost of upstream raw materials such as pure benzene and liquefied gas, as well as the demand from downstream sectors like unsaturated resins.
I. Table of Mean Difference Changes
| Mean Difference Indicator | Value as of September 9, 2026 | Value as of September 8, 2026 | Direction of Change |
|---|---|---|---|
| 5-day Mean Difference (D5) | 360.00 | 15.00 | + |
| 10-day Mean Difference (D10) | 58.75 | 17.50 | + |
| 20-day Mean Difference (D20) | 14.37 | -20.00 | + |
Note: The latest available data is up to September 9, 2026. It is recommended to refer to real-time data.
II. Signal State Determination
The current three mean difference change directions are all positive, indicating a clear upward signal.
III. Conclusion on Trend Direction
Maleic anhydride is currently in a clear upward trend. Reason: The change in the 5-day, 10-day, and 20-day moving average differences from the previous day is completely consistent, and all three types of differences are currently positive, meeting the criteria for a clear upward trend according to the moving average difference method.
IV. Positional Spatial Reference
Maleic anhydride 60-day, 3-month, and 1-year cycle prices are all in the 5th tier (high), indicating limited room for further increases.
Five, Recent Market Dynamics in China
Since early September, the maleic anhydride market in China has gradually risen: On September 4, the market was in a consolidation phase, with factory prices for solid anhydride in Jiangsu and Shandong regions ranging from 7,500 to 7,900 CNY per ton, and liquid anhydride from 7,400 to 7,800 CNY per ton; on September 7, the market saw a slight increase, and from September 8 to 9, major factories continuously raised their quotes. By September 9, the factory prices for solid anhydride in Jiangsu were 8,000 to 8,600 CNY per ton, and for liquid anhydride, 8,300 to 8,400 CNY per ton. In Shandong, the factory prices for solid anhydride were 8,000 to 8,600 CNY per ton, and for liquid anhydride, 7,900 to 8,100 CNY per ton, with price increases generally exceeding 5% compared to early September.
VI. Industry Chain Reference
Upstream: Recently, pure benzene and liquefied gas have also been on an upward trend, providing strong cost support for maleic anhydride.
Downstream: It is necessary to pay attention to the demand follow-up in the main downstream areas of maleic anhydride, such as unsaturated polyester resins, 1,4-butylene glycol, and tetrahydrofuran. If the demand side is insufficient, there may be a possibility of a price drop after the market peaks.
