Basic Approach
In order to gain the trust of society through sustainability promotion activities and to contribute to the creation of a sustainable society, our purchasing activities prioritize stable procurement through continuous transactions with suppliers based on mutual understanding and strict evaluation according to fair and impartial standards, always on an equal footing with our suppliers.
To accurately understand changing user needs, evaluate social utility (environmental conservation, resource conservation, safety, etc.), and continue providing products that satisfy users, we will build trust with our business partners and promote sustainable procurement.
Kanto Denka Kogyo Purchasing Policy
We have established the Kanto Denka Kogyo Purchasing Policy to share our values for a sustainable society with our suppliers. We aim to enhance our mutual corporate value and improve the entire supply chain by having our business partners understand and support these guidelines, and extend them throughout their supply chains.
We actively pursue products and services with low environmental impact and environmental considerations, and as part of our procurement policy, procure materials from companies that follow the RBA Code of Conduct, OECD Due Diligence and mineral resource disclosure rules. We have established these guidelines to work to respect human rights throughout the supply chain and address social issues such as child labor and environmental challenges, particularly climate change. To continue providing stable and safe products, we ensure product and service safety throughout all processes from design to manufacturing, sales, distribution, use, and disposal. We also aim to provide products with minimal impact on stakeholder health and the natural environment by properly managing and reporting chemicals in products (CiP).
To promote initiatives aligned with these guidelines, we perform face-to-face audits to provide an opportunity for mutual growth through active exchange of opinions and information sharing.
