Recently, the acetic acid market in China first weakened and then stabilized. In early August, due to increased production rates and weaker downstream demand in many regions, prices fell to varying degrees. On August 13, the North China region was the first to stop falling and began to increase, with marginal improvements in demand boosting market sentiment. Based on the analysis of average difference indicators, the current acetic acid price is in a phase of fluctuating rebound, supported by its position at a low level within a one-year cycle, indicating limited room for further short-term declines.
