About us

CONTRAF-NICOTEX-TOBACCO GmbH (CNT) is a family owned corporation under German law, with its headquarters in Heilbronn/ Germany. CNT is a worldwide operating company involved in growing, sourcing, developing, processing, extracting and the production of agriculturally originated products. The company operates in Argentina, Germany, India, Zambia, Zimbabwe and is represented with a sales office in Singapore. The activities of CNT are centred on three divisions: Tobacco, Nicotine and Natural Ingredients. The company is supplying directly, or through its subsidiaries and affiliates the tobacco, pharmaceutical and food & beverage industry.

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.


In December 2014 CNT partnered with a start-up from Liverpool to develop Europe’s largest outsourced manufacturing facility for nicotine products.

The new company called Nerudia will focus on the development, production, testing and regulatory compliance of nicotine products specifically for the fast-growing e-cigarette market, supplying brand owners rather than consumers.
