Isophthalic Acid Price Trend Q1 2026
In Q1 2026, Isophthalic Acid prices have increased across global markets, supported by recovering demand from key sectors such as construction, coatings, automotive, and packaging. The upward trend has been primarily driven by tightening supply conditions, rising feedstock costs like PX and naphtha, and increasing energy prices. A significant surge has been observed in March, where prices have risen sharply due to escalating geopolitical tensions in the Middle East, disrupting crude oil supply routes and creating volatility in energy markets.
These disruptions have led to higher production costs, logistical challenges, and limited material availability. Additionally, force majeure situations and reduced operating rates have further tightened supply. Overall, the market has remained highly sensitive to global macroeconomic factors, resulting in strong price escalation during the latter half of the quarter.
