Lotte INEOS Chemical is preparing to take offline its acetic acid unit in Ulsan, South Korea, for a planned maintenance turnaround.
According to market sources, the company is expected to halt operations at the facility by mid-October 2025. While the specific duration of the shutdown has not yet been revealed, the move is drawing attention within the Asian chemicals market as the plant is a significant contributor to regional acetic acid supply.
The Ulsan-based unit boasts a production capacity of 710,000 metric tons per year, making it one of the major facilities in the sector. Any prolonged outage could influence market sentiment, especially at a time when demand fluctuations and global trade uncertainties are already affecting the acetic acid chain.
Although no official statement has been released by Lotte INEOS Chemical, industry participants remain alert to the potential implications of the maintenance schedule. Traders and downstream consumers will be closely monitoring the situation, given the possibility of tightening availability in the weeks ahead.
