  • We believe that the cornerstone of corporate management is to fulfill our economic, environmental, and social responsibilities. We voluntarily reinforce the Company's commitment to these responsibilities and promote benefits to customers, employees, suppliers, communities, and all stakeholders.
  • We monitor supply chain for fire, earthquake damage, health, safety, security, environment, labor, and human rights. The Company places emphasis on the risks associated with suppliers responsible for the supply chain, recognizing that effective supply chain risk management can also serve as a competitive advantage. As such, the Company provides support to our suppliers as needed. We request suppliers to research and manage their current business operations, diversification of raw material procurement, and dispersion of supplier production regions to mitigate the risk of material shortages due to extreme weather or severe natural disasters.
  • We build a risk assessment program for the supply chain and establish a methodology for evaluating supplier sustainability. This method is considered a risk assessment element and is one of the most important references in USJC's procurement strategy, which includes delivery, quality, financial, and business operations elements.
  • UMC Group actively requests its suppliers to sign a declaration prohibiting the use of metals (gold, tantalum, tin, and tungsten) with high risks of conflict and associated with forced labor and human rights violations, from conflict mining countries, or to provide a declaration to prevent the procurement of conflict metals from the Democratic Republic of Congo (DRC) or Central Africa. UMC Group also encourages our suppliers to promote similar management policies. We respect and protect intellectual property rights and conduct fair trade, advertising and competition.
  • We strive to operate our business with integrity and do not engage in any fraudulent or unfair profit-taking.

In order to support this supply chain policy, UMC Group requires our suppliers to comply with the following Code of Conduct.
