Building a cooperative partnership

Code of Conduct for Suppliers


Woco is an internationally active group with the flexibility and organization of a modern medium-sized company based in Bad Soden-Salmünster. The Woco Group has plants, production facilities and partners in Europe, NAFTA and Asia. 
The portfolio includes products for damping and sealing, for preventing vibrations, and for sealing, separating, guiding and controlling media such as air, water and oil, mainly for the automotive industry. The diverse solutions are also used in numerous other industrial applications. These include industrial anti-vibration systems, measurement and control systems, piping systems and railtrack products. Woco products contribute to environmental protection by reducing emissions, immissions and noise.


Woco recognizes its responsibility to its own company, to its business partners, and to the environment and society. In particular, our actions are guided by the values of integrity and fairness, regardless of whether the activity is carried out inside or outside Germany.  We can only achieve this by introducing due diligence requirements in our processes and by our suppliers being guided by the same values described in the Code of Conduct for Suppliers. Due diligence at Woco and our partners and suppliers is based on legal regulations such as the German Supply Chain Due Diligence Act (LkSG) as well as internationally recognized standards such as the International Bill of Human Rights, the UN Guiding Principles on Business and Human Rights, the OECD Guidelines for Multinational Enterprises as well as the ILO Core Labor Standards and the principles of the UN Global Compact. We commit ourselves and our business partners to embed these in their business principles and procedures.

This Supplier Code of Conduct outlines the standards with regard to business integrity and ethics, labor / social standards, environmental protection, competition, general business principles and the associated management system that Woco requires its suppliers to comply with. 

Suppliers must ensure that these requirements are also known and adhered to downstream in the supply chain, by their own employees and by all direct and indirect sub-suppliers.

General principles

The supplier shall comply with the law, regulations and directives. The Supplier undertakes to comply with the applicable laws and other relevant provisions of the countries in which it operates in all business actions and decisions. This also includes the necessary duties of care.

1. Social Responsibility: respect for fundamental and human rights 

The supplier respects and supports the observance of internationally recognized human rights. This includes that the supplier, if potentially negative impacts on human rights are to be feared, establishes processes for human rights due diligence (e.g. Human Rights Due Diligence Process) in his company within an appropriate period of time and takes systematic and appropriate due diligence measures in connection with human rights on the basis of this. The national due diligence laws applicable to the partner, as well as the guidelines of the UN Global Compact initiative and the ILO Declaration on Fundamental Principles and Rights at Work and their Follow-up, and the due diligence processes from the requirements of the United Nations Guiding Principles on Business and Human Rights are authoritative in this regard.

In order to implement these requirements, we expect the supplier to draw up a policy on basic rights and the associated working conditions and human rights within his own company:

  • establish a policy on fundamental rights and the associated working conditions and human rights.
  • Conduct training on this policy.

1.1 Child labor

The supplier observes the regulations of the United Nations on human rights and children's rights and undertakes in particular,

  • the Convention on the Minimum Age for Admission to Employment (Convention 138 of the International Labor Organization)

shall be complied with.

If a national regulation concerning child labor provides for stricter standards, the supplier shall observe these as a matter of priority.

Wages must be paid in full for services rendered and may not be withheld under the law. The supplier shall set clear guidelines for working hours of employees in accordance with ILO Conventions No. 1 and No. 30 on working hours.
