As of September 13, 2026, the acetic acid market in China has recently maintained a strong operating trend. Many production enterprises have increased their quotations by 100-250 CNY/ton in a single day. The overall inventory in the industry is at a low level, and the high prices of upstream raw materials, such as methanol, provide significant support. The market sentiment is strongly bullish. From the perspective of the average difference analysis system, the current acetic acid is in a strong consolidation (bullish) state, with prices at a high level in the 1-year cycle. In the short term, attention should be paid to the sustainability of the price increase and the strength of downstream demand.
I. Table of Mean Difference Changes

II. Signal State Determination
The current combination of changes in the three central differences is (-, +, +), which constitutes a strong consolidation (slightly bullish) signal.
III. Trend Direction Conclusions
The current trend in acetic acid prices is volatile yet bullish. The reason: The directions of change in the three moving averages are not entirely consistent with the previous day, meeting the criteria for a volatile trend. Additionally, the combined signal indicates strong consolidation with a slight upward bias. Meanwhile, fundamental factors—such as low corporate inventories, robust raw material support, and a strong market sentiment inclined toward price increases—provide favorable support, resulting in an overall stronger price trajectory.
IV. Spatial Reference
- 60-day and 3-month cycle prices are both at the 5th level (high): the short-term upside is relatively limited;
- The 1-year cycle price is in the 4th tier (mid-to-high range): There is still some room for upward movement in the medium to long term.
