Pasadena, Texas, and Phoenix, Ariz.-Agrifos Fertilizer LLC and Tessenderlo Kerley Inc. (TKI), said Nov. 3 that they have signed a multi-year agreement extension for TKI to be the exclusive marketer of the ammonium thiosulfate solution produced at Agrifos’ Pasadena, Texas, plant. “This is another significant step in redefining the business model of Agrifos as it transitions from a phosphoric acid producer to a multi-product producer and warehousing terminal,” said Dave Gutacker, Agrifos president. “Combining with a marketing company such as TKI with their extensive knowledge and sales coverage of the ammonium thiosulfate market is the right formula for our continued success.” “Our continued association with Agrifos will allow us to further expand our supply efforts in meeting the demand for sulfur-based nutrient solutions in today’s world agricultural markets,” said Jordan Burns, TKI CEO. The Agrifos facility is situated on the Houston ship channel, producing sulfuric acid, ammonium thiosulfate, phosphoric acid, and ammonium phosphates. Next year Agrifos plans to transition from phos acid production to ammonium sulfate production and increase their terminal business, while expanding their sulfuric acid and ammonium thiosulfate production.
