Tampa — The Mosaic Co. has changed the company it uses to provide transportation for most of its sulfur, phosphoric acid, and finished phosphate products after issuing a request for proposals a few months ago, according to David Townsend, Mosaic spokesman. The contract had been held by CTL Transport of Mulberry, Fla., which lost out to Dillion Transport on its bid to continue the service. Previously, Dillion was hauling primarily sulfuric acid for the company, but will assume the tasks previously conducted by CTL. Townsend said price was a consideration, but was not the determining factor in the decision. The new contract takes effect on March 1.
