Global TDI production in 2025 is estimated at roughly 2.5 to 2.9 million tonnes, reflecting a market supported by flexible polyurethane foam use across furniture, bedding, packaging and automotive interiors, with capacity shaped by feedstock availability, plant reliability and regional demand patterns.
Asia Pacific has added the most new units and now influences international trade flows. Europe and North America rely on upgraded plants that focus on operational reliability, quality control and integration with downstream foam systems. Utilisation shifts follow furniture demand cycles and periods of maintenance at major sites.
Prices respond to plant outages, export decisions and feedstock cost changes. Any restart or increase in exports can rebalance regional price levels quickly. Buyers monitor seasonal foam demand, logistics conditions and operating rate signals to manage exposure.
Key questions answered
Most demand concentrates in 80 20 blends because these grades support the processing window required by slabstock and molded flexible foam producers. High purity grades serve coatings, adhesives, sealants and elastomer applications where reactivity control matters. Low emission grades are increasingly used by furniture and automotive suppliers.
Key questions answered
Phosgene based conversion remains the principal route because it provides predictable yields at industrial scale. Alternative non phosgene routes continue to progress in research and early commercial development. Adoption is gradual because TDI requires robust safety systems, consistent output and proven long term reliability.
Key questions answered
Flexible foam remains the dominant sector because TDI delivers the required elasticity and comfort performance. CASE users value cure speed and control, while automotive and construction markets focus on consistency and emission performance.
Key questions answered
North America maintains a stable TDI footprint supported by integrated feedstocks, downstream flexible foam production and established chemical parks. Imports and exports vary with maintenance cycles and seasonal foam demand.
Europe operates advanced, energy efficient TDI units that compete on quality and reliability. Energy prices, environmental standards and automotive production cycles influence operating rates.
Asia Pacific has added significant capacity, particularly in China. Newer large units influence global availability and shape export flows toward regions with limited domestic production. Regional demand spans flexible foam, CASE and broader manufacturing sectors.
Latin America relies on a mix of domestic production in selected countries and imports to serve furniture and footwear industries. Distributors emphasise safety, quality documentation and reliability.
The Middle East benefits from integrated upstream resources and petrochemical clusters. Many African markets depend on imports and operate distribution systems tailored to local foam and industrial users.
Key questions answered
TDI production begins with aromatics and chlor alkali feedstocks which are converted into TDA and then into TDI. The process involves controlled operating conditions and specialised equipment for reaction, purification and fractionation. Finished TDI requires regulated logistics, including bulk, packaged or iso tank shipments.
Feedstock cost, energy use and recovery systems form a large share of unit costs. Upstream conditions in toluene, nitric acid, hydrogen and chlorine directly influence economics. Transport, storage and safety compliance contribute additional cost layers and vary across regions.
Trade patterns follow production in Asia and established plants in Europe and North America. Export flows shift when major producers change utilisation or when domestic demand changes. Buyers use multi origin sourcing, indexed contracts and buffer storage to manage volatility.
Key questions answered
The ecosystem includes aromatics producers, chlor alkali suppliers, TDA converters, TDI manufacturers, polyurethane systems houses, flexible foam producers, CASE formulators and distributors. Integrated producers hold strong influence because they manage feedstocks, technology and downstream relationships.
Equipment and technology providers support hydrogenation systems, phosgenation units, fractionation columns, waste treatment facilities and safety infrastructure. Downstream buyers require consistent quality, predictable supply and continuous improvement in product performance and environmental attributes.
