Non-conflict minerals policy - Never purchase or use conflict metals

Armed rebel organizations in the Democratic Republic of the Congo (DRC) and surrounding nations operate through metal mining and trading and cause many social and environmental problems, including human right violations, armed conflict, and international disputes. The minerals are tantalum (Ta), tin (Sn), tungsten (W), and gold (Au), also known as the 3T's and gold (3TG). 3TG derived from DRC and neighboring conflict areas are called conflict minerals. As a corporate citizen responsible for protecting human rights and ameliorating armed conflicts in DRC and neighboring nations, we support the Conflict-Free Sourcing Initiative (CFSI) established by the Electronic Industry Citizenship Coalition (EICC) and Global e-Sustainability Initiative (GeSi). We also declare our non-conflict metal policy on our official website to demonstrate our dedication to social responsibility.

Our commitments:

1. Never purchase conflict metals produced from DRC or neighboring nations.
2. Demand our suppliers to never use conflict metals from the conflict areas. If the material is produced in the conflict area, it must be from a non-conflict mine approved by a third party. Please immediately notify us when non-conflict minerals are found to have been unintentionally used in our products, so we may adopt necessary measures. We will also do our best to investigate the source of metal of our suppliers. We adopt CFSI's Conflict Minerals Reporting Template (CMRT) for our investigations. We demand our suppliers to disclose mineral sources and sign the non-conflict mineral commitment letter, and expect our suppliers adhere to our non-conflict mineral policy. Through responsible procurement management, we ensure that Hodaka and its suppliers obtain materials from areas other than the conflict regions and adhere to customer and regulatory requirements.
