China American Petrochemical has taken its purified terephthalic acid unit in Taichung, Taiwan, offline for scheduled maintenance, according to market sources. A contact familiar with the situation told a team member that the shutdown began around September 24, 2025, though the exact duration has not been confirmed and no official statement has been released.
The Taichung facility, with an annual production capacity of 760,000 metric tons, is one of the key PTA producers in the region and a significant supplier to downstream polyester operations. Market participants are watching closely for updates, as the timing and length of the outage could influence regional PTA availability if it extends beyond typical maintenance windows.
Industry observers note that such planned turnarounds are routine for large chemical plants to ensure long-term reliability and efficiency. However, uncertainty over how long the plant will remain out of service has introduced a measure of caution among buyers and traders, who are monitoring inventory levels and alternative supply options in case the downtime is prolonged.
