Health & Crop Sciences Sector

The Health & Crop Sciences Sector is engaged in the manufacture and sale of crop protection chemicals, fertilizers, feed additives, household and public hygiene insecticides, and active pharmaceutical ingredients and intermediates. By providing these products, we aim to contribute to a stable supply of crops, help increase food production in response to an increase in the world population, prevent the spread of infectious diseases, and achieve hygienic and healthy lives.

Oita Works

Oita Works

In 1939, a factory was established as the intermediates production base for dyes and pharmaceuticals by Japan Dyestuffs Manufacturing Co., which was founded in 1916 for the domestic production of synthetic dyes and eventually became the largest dyestuffs manufacturing company in Japan. Following the merger of this company with Sumitomo Chemical, the factory became Sumitomo Chemical's Oita Works in 1944. Subsequently the Works began the production of agricultural chemicals and in 1962 started manufacturing a pesticide known as Sumithion™, which has become popular not only in Japan but also in overseas markets. Using its advanced organic synthesis technologies, the Works is now engaged in the manufacture of a wide range of agricultural chemicals, resorcinol used in adhesives for tires and other applications, and a polymer additive called Sumilizer™ GP. In 2014, the Utajima Pilot Production Department, the Okayama Plant, and the Gifu Plant were added as production sites to enhance the manufacturing organization for pharmaceutical chemicals. The Oita Works is also home to the pharmaceuticals manufacturing plant of Sumitomo Dainippon Pharma Co., Ltd., and plays a core role in the globalization of the Sumitomo Chemical Group's life science chemicals business.

Main Products
Agricultural insecticide (SUMITHION, Clothianidin, SUMICIDIN, CYANOX, and AGROTHRIN), Agricultural herbicide (SUMISOYA, Imazosulfuron, Sulfosulfuron, and CREMART), Agricultural fungicides (DELAUS and RIZOLEX), Polymer additive (SUMILIZER GP), Resorcinol, and Intermediate(LPPS)

Utajima Pilot Production Department

Utajima Pilot Production Department

Utajima Pilot Production Department works to scale up the development of new pharmaceutical chemicals contracted out by both domestic and overseas companies to commercial-scale production. The department is committed to contributing to the actual production of these chemicals through laboratory experiments, and collects chemical and industrial data required for the safe and stable production of pharmaceutical chemicals at the manufacturers' plants.

Okayama Plant

Okayama Plant

The Okayama plant manufactures mainly pharmaceutical chemicals while also producing a variety of specialty fine chemicals. It can flexibly handle everything from batch production for the development phase to a large-scale production, and has the capabilities to scale production in response to the diversified needs of customers.

Gifu Plant

Gifu Plant

The Gifu plant manufactures a variety of specialty fine chemicals while producing mainly pharmaceutical chemicals. Responding to the growing demand for more advanced quality control, the plant has been increasing the proportion of high value-added products it manufactures using its proprietary production and new synthesis methods.

Misawa Works

Misawa Works

In 1949, Sumitomo Chemical established a technology to industrially synthesize pyrethroid, a compound related to the insecticidal component contained in pyrethrums, and constructed a plant to manufacture PYNAMIN on the premises of its former factory in Torishima, Osaka. Subsequently, in response to an increase in demand for the product, the company launched a new plant in 1978 in Misawa City, Aomori Prefecture. Since then, the Misawa Works has been playing an important role as the company's supply base from which a range of pyrethroid insecticides for household use, public hygiene, and agricultural use are exported to countries around the world.

Main Products
Household insecticides (SumiOne, (EMINENCE), FAIRY TALE, Pi Wen Ling,ETOC, PRALLE, PYNAMINFORTE, NEO-PYNAMINFORTE, SUMITHRIN and CRYSRON)
