Conflict Minerals Management

At UMC, we enforce conflict minerals management according to the Disclosures Relating to Conflict Minerals prescribed in Rule 13p-1 of the U.S. Securities and Exchange Act of 1934 of the US Securities and Exchange Commission (SEC). During new supplier selection, UMC requires new suppliers to introduce assessment systems and to present sourcing of minerals from conflict regions. Existing suppliers are also required to actively investigate and verify specified materials (gold, tantalum, tin, and tungsten, cobalt, and mica), sign agreements prohibiting the use of conflict minerals, or provide a declaration thereof. UMC also exercises due diligence when implementing our investigations, and annual supplier audits were carried out to check whether upstream smelters / refiners of the suppliers utilize conflict minerals. Lot traceability for the supply chain is in place to ensure that no conflict minerals have been used. UMC is also an active participant of global advocacy groups such as the Conflict-free Sourcing Initiative (CFSI) of EICC-GeSI. Information on suppliers that meet conflict mineral requirements was acquired from the Conflict-free Smelter Program (CFSP) as a basis for supply chain and source management. Suppliers were also required to refer to the latest Conflict Minerals Reporting Template of EICC to provide information related to conflict minerals. Dedicated UMC personnel were assigned to verify a supplier’s compliance to EICC standards for ensuring the total exclusion of conflict minerals usage.

2016-2022 Complete audits of all conflict minerals suppliers ,comply with RBA certification ,and complete conflict-free supply chain management.

In addition to implementing conflict minerals management according to corporate policy and commitment, UMC also submits Specialized Disclosure (SD) forms to the U.S. SEC while publishing the completed forms on its official website to declare the outcomes of conflict minerals management efforts and demonstrate our commitment to corporate social responsibilities.
