The company was founded in 1982 conducting business on both European leaf tobacco and nicotine supply. Founders Henning Siemann and the late Walter Leupi had both held leading positions in the tobacco and chemical industry respectively. The resulting synergy led to a continuous growth of the company over the years. In 1997, Dirk Siemann and Torsten Siemann took over the full operational responsibility from their father Henning Siemann, who moved on to the supervisory board. In 2005 Sascha Siemann joined his brothers as a Managing Director of CNT.
Under the stewardship of Dirk, Torsten and Sascha, CNT has continued its business development and growth within the ever changing international marketplace.
