Responsible Minerals Sourcing Policy
In recent years, there have been continuing conflicts in Democratic Republic of the Congo and surrounding countries, where the natural resources mined could be the source of funds for armed groups, and also serious social problems such as the human-rights violations and the environmental destructions.
We, Katayama group, are working with our suppliers to achieve responsible sourcing without using minerals related to conflicts and human-rights violations.
