UMC enforces conflict minerals management according to the disclosure rule on conflict minerals released under Rule 13p-1 of the U.S. Securities Exchange Act of 1934 of the U.S. Securities and Exchange Commission (SEC). We have implemented a new supplier evaluation system.  At the new supplier selection stage, we have required the procurement of "conflict-free minerals," which refers to minerals sourced from smelters recognized by the Responsible Minerals Initiative (RMI) or equivalent organizations. Existing suppliers are also required to actively investigate and verify specified materials (gold, tantalum, tin, and tungsten, cobalt, and mica), and sign a Responsible Minerals Declaration. We also conduct due diligence, and through annual supplier audit operations, examine whether suppliers' upstream smelters / refiners use conflict minerals. Adopting a supply chain material traceability and control method to reconfirm the absence of conflict minerals. On the other hand, UMC is also an active participant of global advocacy groups such as RMI of RBA. Through the Responsible Minerals Assurance Process (RMAP), obtain supplier information that complies with conflict mineral requirements as the basis for upstream supply chain management. Require all suppliers to respond to conflict mineral information based on the latest RBA Conflict Minerals Reporting Template (CMRT). UMC's dedicated personnel will then verify whether it complies with RBA-approved smelters to ensure the procurement of conflict-free minerals. If a supplier uses minerals from smelters not listed as qualified under RMAP, UMC will refuse to use the product and request the supplier to submit a plan for improvement within a specified timeframe.

UMC aims to audit all conflict mineral suppliers every three years, having completed audits for all conflict mineral suppliers from 2016 to 2022, and complying with RBA certification, achieving 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.

1. (1) Sector-specific risk suppliers screening: On-site service provider suppliers as defined  by Responsible Business Alliance Code (Responsible Business Alliance, RBA).
   (2) Country specific risk suppliers screening :Conduct an annual BCP risk survey on key raw material suppliers, and classify the country with a supply chain risk map (such as frequent natural disasters, geopolitics, war...)

   (3) Commodity-specific risk suppliers screening :Conduct annual BCP risk surveys on key raw material suppliers, and classify key raw materials with supply chain risk maps (such as: high purchase volume, single source, non-substitutable,...)

2. Tier1 suppliers: Direct transactions with more than 2 orders per year and transaction amount greater than NT$2 million Tier 1 suppliers are also classified by importance such as procurement volume, critical material, and critical/non-substitutable suppliers. In 2023 631ppliers met the criteria. Significant Tier1 Suppliers: The annual purchase amount of the suppliers for more than 80%. Significant High Risk Suppliers:Suppliers who still do not meet UMC standards after providing corrective action plans in the previous year audit.

The following five standards were adopted to regulate and guide suppliers, hoping to establish a supply chain management system with sustainable development.

The core value of UMC's sustainable supply chain is "Sustainability and Mutual-Development." In addition to the existing environmental training for the suppliers, UMC extended its supply chain management to implement initiatives for sustainability, strengthening the guidance for local suppliers to establish sustainable supply chain capability To enhance the awareness of procurement personnel on sustainability initiatives and effectively implement the sustainable supply chain management, UMC held a number of educational training courses to accelerate the development of sustainable supply chain management.
