September 21st, news:
According to the Spotcom AI assistant, on September 20, 2026, the maleic anhydride market in the two major production areas of Jiangsu and Shandong in China showed a general downward trend, with the factory prices of major manufacturers generally decreasing. Based on the average difference analysis model, the current operating signal for maleic anhydride is a moderate correction (bearish), with prices at a high level over the past year. There is insufficient short-term upward momentum, and there is a need to be cautious about the risk of further corrections.
I. Statistics on Changes in Differences of Means
| Average Difference Type | Calculated Value on 2026.09.20 | Calculated Value on 2026.09.19 | Direction of Change |
|---|---|---|---|
| 5-Day Average Difference (D5 = Today’s Price − 5-Day Average) | -65.00 | 65.00 | - |
| 10-Day Average Difference (D10 = 5-Day Average − 10-Day Average) | 266.25 | 332.50 | - |
| 20-Day Average Difference (D20 = 10-Day Average − 20-Day Average) | 565.62 | 541.87 | + |
Note: The latest available data is up to September 20, 2026. It is recommended to refer to real-time data.
II. Signal State Determination
The current deviation change direction combination is (－, －, ＋), corresponding to a moderate correction (bearish, corrective in nature).
III. Conclusions on Trend Directions
The current maleic anhydride price trend is fluctuating. The reason is that the changes in the three averages compared to the previous day are not entirely consistent. The short-term 5-day and 10-day averages have both declined compared to yesterday, indicating that the short-term price is under pressure and declining. Only the long-term 20-day average has slightly increased, providing some medium- to long-term support. Overall, it is in a bearish correction phase.
IV. Positional Space Reference
Maleic anhydride 60-day, 3-month, and 1-year cycle prices are all at high levels, corresponding to the 5th tier out of 5 price tiers, with limited room for further increases and significant resistance to continued upward movement.
V. Price Trends Over the Past Year
VI. Spot Market Dynamics
On September 20, 2026, the maleic anhydride market in Jiangsu region of China declined. The factory price for solid anhydride was around 8,700-9,000 CNY/ton, and the factory price for liquid anhydride was around 8,800-8,900 CNY/ton. The prices implemented by major surrounding factories also decreased.
On September 20, 2026, the maleic anhydride market in Shandong region of China showed a downward trend. The factory price of solid anhydride was operating around 8,700-9,000 CNY/ton, and the factory price of liquid anhydride was operating around 8,500-8,600 CNY/ton. The main factories implemented lower prices.
From September 15-18, the maleic anhydride markets in both regions were in a weak consolidation phase. Factory quotes remained generally stable, and market transactions were mainly driven by rigid demand.
VII. Industry Chain Reference
Maleic anhydride upstream commodities: hydrogenated benzene, n-butane, coker benzene, liquefied petroleum gas, and pure benzene.
Downstream products of maleic anhydride include: polyaspartic acid, tetrahydrophthalic anhydride, succinic acid, tartaric acid, gamma-butyrolactone, unsaturated polyester resins, tetrahydrofuran, and 1,4-butanediol.
