As of October 21, 2026, the Chinese acetic acid market has been affected by the weakening upstream raw material methanol market, weak downstream demand, and low purchasing enthusiasm, leading to consecutive price reductions in various regions recently. Using the average difference method for quantitative analysis, the current trend of acetic acid prices is clearly downward. Over a one-year cycle, the prices are in a high range, with limited room for increase. In the short term, the acetic acid market is expected to continue to operate in a weak state.
