Toluene Diisocyanate (TDI) prices in the US strengthened through late May as the market shifted from steady early-month conditions to a firmer close. Early May saw stable buying and mild pressure, while mid-month activity remained calm before tighter Gulf Coast availability and rising feedstock costs pushed spot indications higher. Demand for TDI held steady throughout the month, with late-May buyers actively covering needs amid limited alternative supply options. Upstream dynamics also supported the rise, as higher toluene costs and constrained import flows tightened effective availability. A short-term production disruption further reinforced the upward trend. Looking ahead, the outlook for TDI in June is firm, with expectations of a moderate incline driven by continued feedstock strength, restricted imports, and limited prompt supply.
