Isophthalic acid markets in the United States cooled after a March rally, as buyers and sellers rebalanced amid volatile landed costs and constrained domestic availability. Early March momentum rested on light merchant inventories and tight domestic-to-import balances, allowing sellers to push higher offers; late March maintained firmness supported by freight premiums and feedstock inflation. In early April the market reversed some gains as prompt rebalancing and spot activity accelerated a correction. Overall tone remains sensitive to upstream aromatics, freight risk premiums, and limited incremental domestic output. Demand across coatings and resin applications supported activity, while import flows and opportunistic buying faced resistance from elevated logistics costs. Kingsport’s constrained run-rate and domestic producers covering about sixty percent of demand kept merchant stocks light and supported peak landed indications in late March. The market continues to reflect tighter supply, higher input costs, and thinner cushions. Near-term outlook points to stability to modest firmness, with volatility likely as freight and upstream costs evolve.
