Responsible Minerals Procurement

TAIYO YUDEN Group established "CSR Charter" and "CSR Code of Conduct" and promotes CSR activities in order to fulfill corporate social responsibility. As "Mutual Trust / CSR" in our Basic Procurement Policy, TAIYO YUDEN Group shall actively practice the CSR management in procurement activities and further establish sound partnership to build mutual trust and development.

There are concerns that the minerals such as tin, tantalum, tungsten, gold (3TG), cobalt and mica in the Democratic Republic of the Congo and adjoining countries or Conflict Affected and High-Risk Areas (CAHRAs) can finance armed groups in those conflict regions through illegal mining and trading of minerals and raise human rights abuses or labor issues such as child labor, forced labor. As one way of fulfilling its social responsibility in its supply chain, TAIYO YUDEN Group implements appropriate measures to procure minerals, ensuring that we do not become involved in such issues through the trade of minerals used in our products.

TAIYO YUDEN Group requests suppliers to understand the TAIYO YUDEN's procurement policy and cooperate with the survey in the procurement process. Furthermore, TAIYO YUDEN Group requests suppliers to procure minerals from the refiners/smelters approved by globally recognized frameworks such as RMI^*1.

TAIYO YUDEN is a member of the "Responsible Minerals Trade Working Group" established within JEITA (Japan Electronics and Information Technology Industries Association), which is an association member of the Responsible Minerals Initiative (RMI). Through this Working Group, TAIYO YUDEN Group collaborates and coordinates with the industry initiative RMI.

TAIYO YUDEN Group is involved in the preparation of educational materials and the operation of the "Responsible Minerals Sourcing Inquiry Briefings" hosted by JEITA. TAIYO YUDEN Group also requests suppliers to participate in these briefings and conducts educational and promotional activities for participating companies regarding the background, survey process, and due diligence of responsible minerals sourcing. Furthermore, TAIYO YUDEN Group promotes awareness of its policy among its suppliers through its supply chain.

TAIYO YUDEN Group policy was revised in accordance with the expansion of target areas and risks from "Conflict risk of DRC and adjoining countries" to "CAHRAs defined by OECD Due Diligence Guidance Annex Ⅱ^*3.

TAIYO YUDEN Group has regularly conducted Responsible mineral survey, including confirmation of country of origin with our suppliers.
TAIYO YUDEN Group conducted the Responsible Mineral Survey to our target suppliers in FY2025, with the target of a 100% response rate.

In the survey to suppliers which handle 3TG, TAIYO YUDEN Group received 100% survey responses from suppliers and identified 348 smelters/refiners. TAIYO YUDEN Group confirmed that the percentage of RMAP^*4-certified smelters is 63% of all smelters. TAIYO YUDEN Group confirmed that all smelters (100%) of the minerals contained in TAIYO YUDEN Group's mainstay products such as multilayer ceramic capacitors and inductors are RMAP certified. Most of these smelters were located in Asia, Europe and the United States.
TAIYO YUDEN Group continues the cobalt and mica survey.

From the survey results so far, no minerals involved in the source of funding for armed groups have been found in all suppliers. TAIYO YUDEN Group will continue regular surveys and disclosure of the results in collaboration with suppliers and the industry.
