Tosoh is one of the largest chlor-alkali manufacturers in Asia. The company supplies the plastic resins and an array of the basic chemicals that support modern life. Tosoh’s petrochemical operations supply ethylene, polyethylene, and functional polymers, while its advanced materials business serves the global semiconductor, display, and solar industries. Tosoh has also pioneered sophisticated bioscience systems that are used for the monitoring of life-threatening diseases. In addition, Tosoh demonstrates its commitment to a sustainable future in part by manufacturing a variety of eco-products.

The Tosoh Group has a long list of accomplishments. We’re number one in Japan in the production of caustic soda and vinyl chloride monomer (VCM), with a production capacity of over one million tons a year for each. Our main plant is nothing less than a self-contained city, with its own electricity generating power plant and its own port and shipping facilities. Dedicated Tosoh ships and trucks guarantee a distribution line of the utmost efficiency and reliability.

On the global stage, Tosoh has the world’s largest production capacity of high-purity zirconia powders and electrolytic manganese dioxide (EMD), with around 20-percent of the market for alkaline dry cell batteries. We’re a leader in key commodity markets in the Asia Pacific region. And we’re a top worldwide producer of quartzware and sputtering targets.

Tosoh is a model of environmental responsibility, too. All Tosoh manufacturing sites in Japan have been awarded ISO 14001 certification for environmental management, and 100% of the products we create adhere to ISO 9000-series International Standards for quality assurance.
