Polyurethane (PU) resin prices in the United States rose 2.56% in the week ending 3 April 2026, supported by tightening supply and sustained cost pressures. Elevated feedstock prices, particularly MDI, TDI, and polyols, were driven by disruptions in crude flows through the Strait of Hormuz amid ongoing geopolitical tensions, inflating production and logistics costs. Reduced operating rates and declining inventories further constrained market availability. On the demand side, construction, automotive, and furniture sectors remained firm, with buyers accepting higher PU resin prices to secure supply. The near-term outlook remains bullish, as continued geopolitical uncertainty is expected to sustain cost pressures, though stabilization may emerge if feedstock markets ease.
Polyurethane (PU) resin prices in the United States registered a week-on-week increase of 2.56% during the week ending 3 April 2026, marking a firm start to Q2 for the versatile polymer system. The advance was underpinned by tightened upstream feedstock availability, elevated energy costs, and persistent geopolitical risk premiums stemming from the ongoing U.S.-Israel-Iran conflict.
Supply-side fundamentals deteriorated notably during the reference week, with cost pressures transmitting through both principal feedstock chains underpinning PU resin production. MDI prices remained stable at elevated levels, while TDI isocyanate values continued to firm, as procurement costs reflected sustained upstream pressure from disrupted crude oil flows through the Strait of Hormuz. These disruptions have inflated feedstock and logistics costs across the value chain resulting in higher PU resin prices. Simultaneously, polyol prices faced upward momentum as propylene oxide — a critical polyol precursor derived from propylene — tracked broader crude-linked petrochemical inflation. Multiple domestic PU resin producers reported reduced operating rates tied to feedstock allocation constraints and compressed margin profiles, limiting spot market availability across both flexible and rigid grade segments. Distributor inventories across the Gulf Coast and Midwest regions were reported to have declined materially, with restocking opportunities constrained by both limited import availability and elevated logistics costs arising from Persian Gulf freight market disruptions.
Demand conditions across key PU resin consuming sectors remained constructive heading into the second quarter. The construction industry — a primary end-use market for rigid PU foam insulation systems — sustained robust procurement activity, supported by an active spring residential and commercial building season. The furniture and bedding segment, a significant consumer of flexible foam grades, reported stable-to-firm order volumes, while the automotive sector continued to draw upon PU resin supplies for seating, headliner, and noise-dampening applications in line with sustained Q1 production momentum. Procurement managers across downstream sectors demonstrated a discernible willingness to accept higher offered PU resin prices, reflecting both genuine supply tightness and a strategic imperative to secure near-term coverage against anticipated further cost escalation driven by geopolitical developments.
The near-term price outlook for U.S. PU resin remains directionally bullish, with the trajectory closely tied to geopolitical developments in the Persian Gulf. Any further escalation of U.S.-Israeli military engagement with Iran — particularly actions affecting Strait of Hormuz transit capacity or triggering expanded sanctions on Iranian petrochemical and crude exports — would exert additional upward pressure on benzene, toluene, and propylene feedstock costs, amplifying PU resin production economics. Conversely, a ceasefire or credible diplomatic de-escalation could release pent-up supply and moderate spot premiums in H2 2026. In the interim, market participants are advised to monitor Federal Reserve monetary policy communications and domestic construction sector indicators alongside geopolitical developments as complementary determinants of PU resin demand resilience.
