In order to improve issues such as human rights violations and environmental destruction that occur when mining minerals in conflict regions in Africa, BH strives to build a responsible supply chain management system and fulfill its social responsibilities by actively participating in the ban on the use of conflict minerals. Minerals used in BH's products are based on international standards and guidelines such as the OECD Due Diligence Guidance, and we strive throughout the supply chain to procure ethical and socially responsible parts.

Conflict minerals refer to the four major minerals, such as tin, tantalum, and tungsten gold mined in the Democratic Republic of the Congo and nine neighboring countries. The target countries are 10 countries such as Sudan, Uganda, Rwanda, Burundi, Tanzania, Central Africa, Congo, Angola, and Zambia, including the Democratic Republic of the Congo. Armed forces such as rebels and government forces dominate the mining and distribution of minerals in the area, which is believed to secure funds and continue the conflict. This causes human casualties as well as human rights issues such as human rights violations of local residents and labor exploitation in the process of mineral extraction, and social problems such as environmental pollution.

BH has established policies to prevent environmental pollution, human casualties, labor exploitation, and human rights violations in the conflict areas, and excludes the use of conflict minerals from the stage of purchasing raw materials. In order to establish a system of not using conflict minerals, we have established and implemented a management process for the supply chain of conflict minerals that meets the OCED Due Diligence Guidance. We will actively support activities to ban the use of conflict minerals promoted by the Responsible Minerals Initiative (RMI). Except for conflict minerals supplied by smelters and refineries that have obtained certification through RMAP (Responsible Minerals Assurance Process), the use of unethically mined conflict minerals is prohibited. BH thoroughly investigates whether conflict minerals are included in the product using the Conflict Minerals Reporting Template of the Electronics Industry Citizenship Coalition (EICC) in the United States, and has established a basic policy of providing products that have gone through a legal and ethical distribution process and is operating a partner management process. We are making efforts to help understand the internal and external Conflict Minerals Regulation Act through training for BH employees and partner companies. Through various communication channels such as customers, partners, affiliates, and specialized organizations, we are closely monitoring related trends and conducting reasonable response activities.

BH will do its best to ensure responsible mineral procurement so as not to use unethical minerals that cause human rights violations and environmental destruction, as well as minerals related to armed forces in conflict areas. Through supply chain due diligence and training, we will raise awareness of the regulation on conflict minerals so that we can respond voluntarily.
