This report is based on the mean difference analysis system, combining the latest spot quotes for MIBK, moving average data, and cyclical price positions as of September 17, 2026, to conduct market analysis. The current MIBK market is in a moderate correction phase, with prices at a high level over the past year, and the upward space is limited. This is for reference by industry practitioners in China.
I. Table of Mean Difference Changes
Difference Type Today's Value (CNY/ton) Yesterday's Value (CNY/ton) Direction of Change
5-day average difference (D5) -246.66 -120.00 -
10-day average difference (D10) 600.00 920.00 -
20-day average difference (D20) 1317.50 1245.84 +
Note: The latest available data is up to September 17, 2026. It is recommended to refer to real-time data.
II. Signal Status Determination
The current three average difference change direction combinations are (－, －, ＋), which align with the characteristics of a moderate correction (bearish, corrective nature) signal in China.
III. Conclusion on Trend Direction
The current MIBK price trend is fluctuating. Reason: The changes in the three averages compared to the previous day are not entirely consistent, which does not meet the criteria for a clear upward or downward trend. This is considered a mild pullback within a fluctuating range, with a short-term bearish attribute.
Latest spot market situation: On September 17, 2026, the mainstream negotiation price for MIBK in East China's ex-works bulk water pickup was 13,500-13,600 CNY/ton. Anhui Zhonghuifa New Materials' 50,000 tons/year MIBK plant is operating normally, with moderate inventory, and limited spot sales. The quoted price on that day was 15,000 CNY/ton.
IV. Positional Spatial Reference
The MIBK price is at the 5th level (high) of the 1-year cycle, with limited room for further upside; the 60-day and 3-month cycles are also at high levels, so caution is advised regarding the risk of a pullback from these elevated levels.

VI. Industry Chain Reference
MIBK upstream products include diacetone alcohol, isopropanol, and acetone; downstream products include dewaxing agents, extraction agents, antidegradants, and solvents. On September 17, 2026, the price of acetone from Sino-Saudi Tianjin Petrochemical in China was reduced by 400 CNY/ton to 8,900 CNY/ton. The 350,000 tons/year phenol and acetone unit is operating normally with appropriate inventory. Changes in the prices of upstream raw materials may subsequently affect the cost of MIBK.
