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 Responsible Minerals Initiative (RMI) of RBA. Information on suppliers that meet conflict mineral requirements was acquired from the Responsible Minerals Assurance Process(RMAP) as a basis for supply chain and source management. Suppliers were also required to refer to the latest Conflict Minerals Reporting Template(CMRT) of RBA to provide information related to conflict minerals. Dedicated UMC personnel were assigned to verify a supplier’s compliance to RBA standards for ensuring the total exclusion of conflict minerals usage. If the supplier does not use minerals from qualified smelters in the RMAP list, UMC will refuse to use the product and ask the supplier to propose an improvement plan within a time limit.

The goal of UMC is audit all conflict minerals suppliers every three years.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.

UMC have a high regard for the sustainable management of suppliers. In terms of sustainability, we focus on the environmental,

social and corporate governance requirements of suppliers. In response to the supplier's sustainable management, UMC established the "Supply Chain Management Committee" and formulated the "Supplier Evaluation Mechanism" (or the Dow Jones Sustainability Index Selection Mechanism) to regularly manage, evaluate, coach, and track the improvement efforts that vendors are making. The management object of the Supplier Assessment Mechanism evaluation is crucial suppliers who support production, including equipment suppliers, raw material suppliers, facility engineering suppliers, consumables and component suppliers. Each year, these crucial suppliers’ Q (Quality,22.5%), C

(Cost/Financial,22.5%), D (Delivery,22.5%), S (Service,22.5%), S (Sustainability,10%) are evaluated.

Supplier with good sustainable performance, UMC will hold public commendations from time to time UMC supplier evaluation mechanism defines sustainable supplier rating and corresponding measures, and incorporates sustainable management requirements items into the evaluation items according to the level of importance, and send out The questionnaires to suppliers for reply anually. Suppliers having certifications related to environmental protection or hazardous substance management (ISO 14001, TS 16949, or QC080000) or can demonstrate capabilities in fulfilling the requirements of the RBA Code of Conduct may receive extra points. This incentive was provided to help guide and encourage suppliers to comply with these standards. 65% of process-releated significant vendors acquire ISO 14001 or other international EHS Management certifications.
