CP50: Sumitomo Chemical America Inc.
Company Information
The origins of Sumitomo Chemical can be traced back to 1913 when the company used sulfur dioxide emissions from the Besshi Copper Mine in the Shikoku region of Japan to produce calcium superphosphate fertilizers, thereby reducing pollution from the mine. In addition to helping preserve the environment by preventing the emission of pollutants, the company was thereby also able to contribute toward increasing the harvest of agricultural products. Sumitomo Chemical thus found its start with the solving of environmental problems and the goal of improving living standards. Today, the Sumitomo Chemical Group includes some 100 companies operating around the world in six business sectors: basic chemicals, petrochemicals and plastics, fine chemicals, IT-related chemicals, agricultural chemicals, and pharmaceuticals. Sumitomo Chemical's U.S. headquarters is based in New York. The parent headquarters is located in Tokyo, Japan. The majority of the company's sales is based in the petrochemicals sector, comprising 32% of total company sales.
