Tosoh to Strengthen Bromine Production Capacity

Tokyo, Japan—Tosoh Corporation plans to expand its production capacity for bromine for use in flame retardants, fungicides, medicines, and agrochemicals at its Nanyo Complex in Shunan City, Yamaguchi Prefecture.

Tosoh is Japan’s largest manufacturer of bromine, which the company sells domestically and throughout Asia. While current demand for bromine is steady, particularly in Asia, remarkably insufficient supply in China is driving continued tightness in the bromine supply-demand balance.

Tosoh seeks to bolster its production capacity by renewing its bromine production facility. This will enable the company to maintain stable supply to meet expanding demand for bromine and to broaden the scale of its business and strengthen its profitability.
