September 28th News
According to the Spotcom AI assistant, this report is compiled based on the spot price system. As of September 27, 2026, the national average spot price of maleic anhydride in China was reported at 9,650 CNY per ton, unchanged from the previous day. Based on the mean difference method, the current maleic anhydride market is in a slightly bearish fluctuation phase, with prices at a high level within the past year. The potential for further increases is limited, and it is recommended to closely monitor changes in upstream raw material prices and the recovery of downstream demand.
Note: The latest available data is up to September 27, 2026. It is recommended to refer to real-time data.
I. Table of Finite Differences
| Mean Difference Indicator | Today’s Value (2026.9.27) | Yesterday’s Value (2026.9.26) | Direction of Change |
|---|---|---|---|
| 5-Day Mean Difference (D5) | 0 | 0 | No Change |
| 10-Day Mean Difference (D10) | -15 | -32.5 | Upward |
| 20-Day Mean Difference (D20) | 284.37 | 371.87 | Downward |
II. Signal State Determination
The current three differences in direction are not entirely consistent, indicating a volatile market. The portfolio characteristics match the rebound (biased bearish) type.
III. Conclusions on Trend Directions
The current trend is oscillating (with a bearish bias), reason: the changes in the 5-day, 10-day, and 20-day moving average differences from the previous day are not fully aligned, failing to meet the criteria for a clear upward or downward trend, and the overall situation is in a high-level consolidation phase with a bearish bias.
IV. Positional Spatial Reference
Maleic anhydride 60-day, 3-month, and 1-year cycle prices are all in the 5th tier (high) range. The current price is already at the top of the range over the past year, with limited room for further increases, and there is a need to be cautious of the risk of a pullback from these high levels.

VI. Regional Market Trends and Industry Chain Insights
Regional Market Update: On September 23–24, maleic anhydride prices rose in Jiangsu and Shandong. In Jiangsu, solid maleic anhydride was quoted at RMB 8,400–9,000 per ton, while liquid maleic anhydride ranged from RMB 8,600 to 8,800 per ton. In Shandong, solid maleic anhydride was priced at RMB 8,400–9,000 per ton, and liquid maleic anhydride at RMB 8,200–8,500 per ton. Major producers raised their ex‑factory prices, with quotations remaining stable from September 25 to 27.
Upstream and downstream of the industrial chain: Upstream raw materials include hydrogenated benzene, n-butane, coking benzene, liquefied gas, and pure benzene. Currently, the prices of upstream pure benzene and liquefied gas are at high levels, providing strong cost support for maleic anhydride. Downstream applications include polyaspartic acid, tetrahydrophthalic anhydride, succinic acid, unsaturated polyester resins, tetrahydrofuran, 1,4-butanediol, etc., with overall stable demand in China.
