Responsible Minerals Procurement

Taiyo Yuden is dealing with the issue of conflict minerals as a part of its Corporate Social Responsibility (CSR) activities. The OECD recommends establishing a complaint handling mechanism for conflict minerals matters in the "OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas," and Taiyo Yuden is establishing the mechanism in accordance with the intent of OECD.

Taiyo Yuden will check your concerns and information, and take corrective action based on its "Responsible Minerals Procurement Policy" if necessary.
