Tosoh USA, Inc. was initially established as Tosoh Corporation's first US representative office in NY in 1964 and has grown to become the corporation's main sales, marketing, and business development center in North America. Currently, based in Grove City, Ohio, Tosoh USA markets and sells a variety of chemical products produced by Tosoh Corporation and its affiliates that go into a myriad of industries and markets. Silica glass (a.k.a. quartz), organic chemicals, and specialty polymers are just some of the essential Tosoh USA provides to customers who produce everyday things.
