Sustainable Supply Chain Management

Sustainable Supply Chain Management Strategies

Nanya Technology's screening criteria for direct production material suppliers mandate not only ISO 9001 and ISO 14001 third-party verification but also rigorous internal evaluations. Utilizing an electronic supplier evaluation management system, we assess suppliers across six key aspects: quality, delivery, service, cost, technology, and sustainability. Among the evaluation criteria, the sustainability management indicator (sustainability) accounts for 19% of the total score to ensure suppliers meet the Company's sustainable supplier management requirements. Once suppliers are approved, Nanya Technology further verifies the implementation status of sustainable supplier management through document reviews and on-site audits.

Sustainable supplier risk management
Implement risk assessment through self-evaluation questionnaires for suppliers, and strengthen supplier risk management through audits and improvement tracking.
Supplier cooperation and exchanges
Periodically organize supplier conferences and supplier evaluations on the basis of cooperation and mutual aid, and provide guidance for suppliers to increase social, economic, and environmental benefits, in order to achieve sustainable development of suppliers.
Improve the sustainability of suppliers
Nanya pays attention to environmental and social sustainability issues while pursuing economic benefits, and continues to work with suppliers in projects related to sustainability.
Responsible Mineral Procurement
Nanya is committed to a responsible procurement management strategy for the ban on conflict minerals to satisfy current and future market, legal, and regulatory expectations.

Sustainable Supply Chain Management Process

Nanya Technology has established a comprehensive supply chain management procedure. We ensure our suppliers meet our standards and requirements through a cycle involving five key processes: sustainability regulation, active risk assessment, sustainability risk assessment questionnaire, sustainability audit/improvement guidance, and supplier capacity building. Through risk assessment and audits, we monitor the risk level of our supply chain and guide suppliers to improve and build capacity, gradually strengthening the sustainability performance of the supply chain.

Supply Chain Sustainability Projects

To address evolving sustainability trends and updates, Nanya Technology enhances suppliers' sustainability as well as their awareness and capacity in sustainable development through seminars and project-based guidance.

Sustainable Development Mutual Benefit Initiative

As the era of carbon pricing approaches, Nanya Technology continues to advance low-carbon transformation across its supply chain while actively investing in the in-house development of 10nm-class advanced process technologies. Through industry-academic technological collaboration, cross-sector capability sharing, and the implementation of digital tools, we empower our suppliers and jointly strengthen the momentum for low-carbon transformation, hoping to build a resilient, competitive, and sustainable industry chain. Therefore, in 2023, Nanya Technology collaborated with 10 suppliers to join the DRAM Supply Chain Low-Carbon Transformation Program led by the Industrial Development Administration, Ministry of Economic Affairs. This two-year program allowed Nanya Technology to join forces with its supply chain partners as well as the Industrial Technology Research Institute and National Taiwan University of Science and Technology. Completed in December 2025, the program delivered 26 projects and achieved a carbon reduction of 8,536 metric tons—surpassing the original estimation of 6,300 metric tons and reaching a 135% achievement rate.

Responsible Mineral Sourcing Management

Nanya Technology is committed to managing conflict-free minerals and implementing a responsible procurement strategy. We have also published a Responsible Mineral Sourcing Policy to align with the requirements for responsible metal procurement, uphold our responsibilities as part of the Responsible Business Alliance (RBA), and achieve the goals of the Responsible Minerals Assurance Process (RMAP). Since 2022, Nanya Technology has added the statement "Comply with RMI Policy and Conflict Mineral-Free" to its product labels, declaring that the company's products meet the mandate of the Responsible Minerals Initiative (RMI) and are free from conflict minerals. RMI Grievance Mechanism to implement responsible mineral procurement management, Nanya Technology has established a responsible mineral grievance channel for employees, suppliers, customers, and other stakeholders to raise concerns, complaints, or suggestions related to conflict minerals, cobalt, mica, and other responsible minerals. We will handle these matters carefully in accordance with relevant procedures and keep the complainant's information confidential.

Result of Responsible Mineral Procurement Due Diligence

As a DRAM supplier, Nanya Technology conducted due diligence on its supply chain. After comparing its findings with the Responsible Minerals Initiative (RMI) qualified smelter list, 250 smelters or suppliers were identified in the 2025 supply chain investigation. Among them, 211 smelters or suppliers reported information concerning the gold, tantalum, tin, tungsten, cobalt, and mica currently used in our company's product supply chain. Approximately 46% (115) of these smelters reported that their mineral sources might originate from the Democratic Republic of Congo or adjoining countries, or from recycled/scrap metals. According to supply chain reports, these 115 smelters have all confirmed that their mineral sources comply with the Responsible Minerals Assurance Process (RMAP) policy requirements and have been approved as legitimate smelters by the Responsible Minerals Initiative (RMI).
