USA polyurethane resin prices surged 8.86% during the week ending March 13, 2026, driven by escalating MDI and TDI isocyanate feedstock costs and polyol price increases linked to Middle East conflict disruptions. The Strait of Hormuz closure severely constrained naphtha flows to Asian chemical complexes, forcing force majeure declarations and tightening global aromatics availability. Ocean freight disruptions added emergency surcharges reaching $2,000 per container as vessels rerouted around Africa. US buyers in construction, automotive, and furniture sectors commenced aggressive procurement and strategic stockpiling ahead of spring demand. Industry analysts anticipate continued firmness as supply chain vulnerabilities intensify from prolonged conflict affecting feedstock availability and logistics networks through March-April.
Polyurethane resin prices in the United States surged 8.86% during the week ending March 13, 2026, as escalating feedstock costs combined with global supply chain disruptions to drive the sharpest weekly advance. The increase reflected intensifying cost pressures from Middle East conflict-driven logistics constraints and mounting procurement urgency among downstream manufacturers facing uncertain supply availability.
US polyurethane resin manufacturers faced substantial cost inflation as methylene diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI) import prices increased sharply, with suppliers quoting higher prices for March deliveries following similar February gains. The closure of the Strait of Hormuz since late February severely constrained naphtha flows from Middle Eastern refineries to Asian chemical complexes, forcing producers including Indonesia's Chandra Asri to declare force majeure and Japanese buyers to cancel import tenders, tightening global aromatics availability that feeds into PU resin production pathways. Simultaneously, polyol costs firmed as propylene feedstock prices tracked crude oil movements, with propylene oxide margins compressing under energy cost pressures that manufacturers passed through to polyether and polyester polyol quotations. Ocean freight disruptions compounded these feedstock challenges as container vessels rerouted around Africa's Cape of Good Hope added 10-14 days to transit times from European and Asian suppliers, with emergency surcharges reaching $2,000 per container elevating landed costs for imported isocyanates and polyols arriving at US Gulf Coast terminals for polyurethane resin production.
US buyers in construction insulation, automotive seating, and furniture cushioning applications commenced aggressive procurement as manufacturers sought to secure polyurethane resin supplies ahead of anticipated spring building season demand and Q2 automotive production schedules. Construction sector activity demonstrated particular urgency as contractors positioned materials for residential and commercial projects despite economic uncertainty from geopolitical tensions. Automotive original equipment manufacturers accelerated polyurethane resin procurement for seating and interior component production lines, with robust light vehicle assembly forecasts supporting baseline demand even as some discretionary purchases faced scrutiny amid inflation concerns. Beyond routine seasonal restocking, polyurethane resin market participants reported widespread strategic stockpiling behavior as purchasing managers sought to establish safety stock buffers against potential supply disruptions.
Looking ahead, industry analysts anticipate continued firmness in US polyurethane resin prices as global supply chain vulnerabilities intensify from prolonged Middle East conflict affecting feedstock availability and logistics networks. The risk of additional Asian petrochemical producers reducing operating rates or declaring force majeure amid naphtha shortages threatens to further tighten MDI and TDI export availability, potentially forcing US buyers to compete more aggressively for limited supplies and supporting additional polyurethane resin price increases through March and April. Market participants expect polyurethane resin prices to remain elevated as long as crude oil sustains levels above $85-90 per barrel and shipping disruptions persist, with procurement strategies shifting toward longer-term contract commitments and inventory building to mitigate supply uncertainty.
