Supplier Code of Conduct

Centrotherm Systemtechnik GmbH, together with its affiliated companies (collectively "Centrotherm"), understands sustainability as an essential component of our business processes. As a technology group with a high level of materials expertise, we procure raw materials, goods and services from suppliers worldwide in order to ensure the sustainable success of our customers with innovative product and service solutions. 

The basis for this is responsible corporate management geared towards long-term value creation. For this reason, we integrate suppliers directly into our sustainability strategy. In our procurement activities, we pay attention not only to process-related, economic and technical criteria, but also to social and ecological aspects such as human rights, working conditions, corruption prevention and environmental protection.

In the area of conflict between product/performance, market, region and process, costs, quality, reliability, innovation and sustainability are key factors for us in selecting and evaluating suppliers. Centrotherm expects its suppliers to comply in their activities with the applicable national laws, the principles of the United Nations Global Compact and this Centrotherm Supplier Code of Conduct. Furthermore, they are expected to implement suitable processes that support compliance with the applicable laws in their companies and promote continuous improvement with regard to the principles and requirements of the Centrotherm Supplier Code of Conduct. Furthermore, Centrotherm expects its suppliers to ensure that their affiliated companies also comply with and acknowledge all principles and requirements described herein.
