Developing and manufacturing innovative, competitive products for our globally active customers requires outstanding dedication from all Winkelmann Group companies and sites and constant openness to new ideas from every corner of the world. To meet this requirement, we need highly capable, reliable suppliers.
    On average 50% of Winkelmann Group turnover is comprised of raw materials and services purchased externally. Our success is therefore highly dependent on the capabilities of our selected suppliers.

    Your Perspective
    We are always on the lookout for new, highly capable suppliers, who are prepared to make a major contribution to the success of our company. In return, we offer partner businesses excellent growth prospects and a long-term trust-based business relationship with a solid, internationally-oriented group of companies.

    We expect our suppliers to work in genuine partnership with us – we demand a lot from our partners.

    What we expect:
    • deadlines to be honoured and flexibility
    • responsibility to be taken for quality
    • cost transparency and improvements
    • environmental and social responsibility
    • product and service innovation

  • Procurement Organisation


    The Winkelmann Group is a group of companies made up of multiple companies and factories with their own operational structures. Strategic management and coordination of procurement is the responsibility of the head of strategic procurement and four product group managers.

    The procurement organisation thus consists of clearly focused units – multi-site strategic procurement and site-specific Operational Procurement. The Strategic Procurement team is responsible for procuring key material groups such as raw materials, energy, etc.

    By bundling demand from multiple sites and sourcing materials and services globally, we aim to systematically realise synergies and exploit potential for cost reductions.

    The site-based Operational Procurement teams are responsible for procuring materials for day-to-day operational requirements, always in coordination with the Strategic Procurement unit. They form the direct link between internal points of consumption and our suppliers.

  • Suppliers Code

    Our company’s social and environmental responsibilities are increasingly coming to include our choice of business partner, in particular suppliers and service providers. The Winkelmann Group’s head of Strategic Procurement has therefore decreed that, in addition to price, quality and reliability of supply, environmental and social factors must also be taken into account when selecting suppliers.

    Since May 1, 2010, a Winkelmann Group Suppliers Code defines requirements which must be met by suppliers of goods, capital goods and services. The core points of the code are ethical conduct, respect for human rights, socially acceptable working conditions, adherence to environmental standards and the use of management systems.

    The principles set out in this code reflect the Winkelmann Group’s mission and are based on the following international conventions and standards:

    • The principles of the United Nations Global Compact
    • The Organisation for Economic Co-operation and Development’s (OECD) guidelines for multinational enterprises
    • International Labour Organisation (ILO) agreements
    • The International Chamber of Commerce (ICC) Business Charter for Sustainable Development
    • SA 8000 (standard for socially responsible company management)

    The Winkelmann Group expects its suppliers to promote adherence to these principles in their own supply chains.
