Sinopec Mitsui Chemicals has halted operations at its Bisphenol A (BPA) facility in Caojing, Shanghai, following an unplanned maintenance shutdown that began on September 9, 2025, according to a market source in China.
The company has not issued an official statement on the outage, and the timeline for restarting the plant remains uncertain, keeping market participants on alert for potential supply impacts.
The Caojing plant is a significant regional producer with a nameplate capacity of 120,000 metric tons per year, making it an important source of BPA for downstream applications such as polycarbonate and epoxy resins. Traders and downstream manufacturers are expected to monitor developments closely, as any extended outage could tighten availability and influence prices in the Asian market.
