Our History at Twin State Inc.
Twin State, Inc., formerly Twin-State Engineering and Chemical Company is a privately held Iowa corporation, incorporated in 1958, with three major manufacturing facilities (Durant, Iowa; Hampton, Iowa; and Janesville, Wisconsin) with over 53 years of fluid fertilizer leadership. We manufacture and market a complete line of liquid fertilizers, including suspensions, all NPK and 10-34-0 starters and minor elements (sulfur, zinc, boron, etc.). In addition, Twin State markets 32% Nitrogen solution and has 3 terminals and access to others on the river.
Twin State, Inc, formerly Twin-State Engineering & Chemical Company, was incorporated in March, 1958, in the state of Iowa. The company was founded by brothers Hovey and Scott Tinsman and continues to operate as a privately held firm. The initial purpose was to design a manufacturing process for clear liquid fertilizer analyses for the agricultural market in eastern Iowa and northwestern Illinois. A small pilot plant was constructed in 1959 in Walcott, Iowa, and all products were moved through a small number of newly established dealers. In addition, mixing systems were constructed for the dealer network.
As Twin State, Inc, expanded, employee numbers grew from two to approximately 125 full-time and some 200 seasonal. Twin State, Inc, pioneered the development of the “pipe reactor” to produce clear polyphosphate 10-34-0, N-P-K starter grades, and SLX high potash suspension grade analyses. Three production plants were constructed in order to reach a much larger market. The distribution system evolved whereby nitrogen solutions and concentrated solutions of phosphate, potash, and sulfur are shipped to over one-hundred independent and cooperative dealer locations for further mixing to meet the growers’ needs. All these products travel to the market under the trademark, “Liqui-Grow.”
People buy from people. Twin State, Inc, has concentrated on hiring quality staff in all areas… that includes administration, production, research, and sales. Training and teamwork, in addition to product quality and timely delivery, have been critical to our growth.
Twin State continues to create innovative new products. Most recently, they designed an automated railcar cleaner and railcar cleaning service.
