Our purchasing aims to ensure the long-term, demand-oriented supply for our production facilities and services centres with products and services. We focus on efficient suppliers and providers with whom we cooperate on the basis of long-term commitment and trust. Clear and accessible supplier evaluation criteria are the basis of the further development of our supplier portfolio. 

Our suppliers know us as a competent, reliable and fair partner. Both solicitation and awarding of contracts are transparent processes. 

Framework contracts and standardised agreements ensure fair competition and a high level of dependability for both sides.
