2. NOK Group Sustainability Procurement Guidelines

We, NOK Group, are committed to being an entity that fulfills the role of driving efforts toward the realization of a sustainable society while upholding the principle of fair and free competition, through creating added value that is socially useful, generating employment, and acting autonomously and responsibly.
We believe that if we are to achieve this goal, it is essential that our awareness is shared across suppliers and to work together throughout the supply chain to realize a sustainable society, and established NOK Group Sustainability Procurement Guidelines as our code of conduct.
We ask our suppliers, who are important business partners of the NOK Group, to understand the purpose of this guideline and to implement it on their own, and we also ask their own suppliers to implement it.

6. Green Procurement Guidelines

NOK's production activities are centered on industrial components made from polymeric materials, such as synthetic rubber and resin. We are committed to environmental conservation activities such as managing environmentally hazardous substances used in production processes, saving energy and resources, and reducing waste.
To extend these controls beyond production processes to procurement activities, we have established the NOK Group Green Procurement Guideline. Controlling environmentally hazardous substances and building a system to guarantee the non-inclusion of these substances throughout the supply chain are our priorities.
