NORTH AMERICA
The American subsidiary Tessenderlo Kerley Inc. (TKI) is based in Phoenix, Arizona.
TKI is the world’s largest producer of ammonium thiosulphate (THIO-SUL ® , ATS) and
potassium thiosulphate (KTS ® ). TKI has 13 production plants in the United States.
These plants are generally located near refineries whose acidic gases TKI processes
into liquid sulphur-containing fertilisers and derivatives, the vast majority of which
(60%) are used in agriculture and the balance in process chemistry.
