Values and Goals
Our collaboration is based on shared values and goals that secure our competitiveness and mutual success in the long term. We count on a constructive partnership and enduring cooperation as well as fair market conditions in good times and bad.
Quality and Reliability
You rank among the best in your market and support us with innovative products, reliable services, punctual deliveries and competitive prices.
We also expect our partners to use a management system that meets ISO 9001 (quality) requirements or one compatible with GMP (Good Manufacturing Practice). Industrial suppliers must be certified to ISO 14001 (environmental protection).
Sustainability and Social Standards
Our ambition is to contribute to a more sustainable society and to balance ecological and socio- economic interests within the entire supply chains. WACKER has implemented an ISO 50001-compliant energy management system at its German sites.
WACKER has joined international initiatives such as Responsible Care® and Global Compact and fully supports the principles described therein. We also require our suppliers, business partners and / or potential new suppliers to follow these principles.
These guidelines are summarized in our WACKER supplier code of conduct.
You can anonymously report information on compliance-relevant topics worldwide via our digital whistleblower system.
As a member of Together for Sustainability (TfS), which is an alliance of ~36 chemical companies, WACKER monitors the sustainability performance of our suppliers regularly.
WACKER engages all key suppliers to either have an Ecovadis assessment score exceeding 46 or to pass a TfS Audit without any major deviations.
Digital Collaboration with our Suppliers
We are counting on digitalization, innovation, efficient procurement processes and cutting-edge IT systems to achieve this goal. We expect our suppliers to support us in these endeavors by using standard IT interfaces.
WACKER strives for a highly efficient, digital collaboration with our suppliers.
This includes in particular:
electronic tendering via SAP ARIBA; provision of e-catalogues; electronic processing of the purchasing process from purchase order to payment via standardized IT platforms, in particular SAP ARIBA.
Therefore, WACKER expects our suppliers to support this digital collaboration platforms as an important prerequisite to become or remain among our preferred suppliers.
