Isophthalic Acid Price Trend Q3 2025
In Q3 2025, Isophthalic Acid prices showed mixed trends in key markets. Prices declined in South Korea, Taiwan, Japan, Saudi Arabia, the USA, Indonesia, and India, driven by reduced demand from key sectors like automotive, construction, and textiles, along with logistical challenges and rising feedstock costs.
In contrast, Spain and Brazil saw price increases of 1.71% and 7.05%, respectively, supported by demand recovery in packaging and automotive industries. The weakening of local currencies and higher freight costs contributed to price fluctuations. The market outlook for Q4 2025 remains unpredictable, with recovery in industrial demand being key to price stabilization.
