Mitsui Chemicals to Optimize TDI Production Capacity

Mitsui Chemicals, Inc. announced plans to optimize the production capacity of its Omuta Works’ toluene diisocyanate (TDI) plant in July 2025. TDI is used as a raw material in the production of polyurethane.

Objectives and Background

Mitsui Chemicals currently manufactures and sells TDI (Production capacity 120,000 tons per annual) for use as a basic material in the isocyanate chain at the Omuta Works. However, given supply and demand trends in Japan and overseas, Mitsui Chemicals has decided that a reduced output of around 50,000 tons per year will be optimal going forward.
While maintaining a stable supply setup to meet domestic demand for TDI, the Omuta Works will contribute to expansion in growth domains as part of Mitsui Chemicals’ business portfolio transformation by bolstering competitiveness as the company’s principal center for the manufacture of high-performance products, including ophthalmic lens materials and agrochemical products.
