Sustainable Supply Chain

Considering corporate sustainability from the perspective of the value chain, sustainability factors must be incorporated into the work design and training from inbound logistics and manufacturing to outbound logistics to effectively promote sustainable supply chain management. 
In 2023, Winbond focused on a dual-axis transformation strategy, encompassing digitalization and decarbonization, complemented by an ecosystem approach in work design to implement sustainable supply chain management initiatives. This encompasses managing supplier from the source, conducting internal sustainability training, executing procurement tasks, establishing internal green logistics systems, and closely collaborating with outsourcing partners. Faced with a challenging business environment, Winbond emphasizes the importance of maintaining innovative management thinking and the ability to rapidly adjust and react. This ensures the evolution of timely and adaptive business capabilities with suppliers, ultimately achieving the goal of a sustainable supply chain.

Sustainable Risk Assessment

Sustainable Supply Chain Risk Management

Winbond's supply chain structure is composed to meet customer quality and delivery requirements, as well as Winbond's own production and routine administrative needs. This demand aggregates enterprises from various countries worldwide (geographical aspect) with different production bases, supplying products, technologies, and services from various industries (industry aspect). Consequently, the supply chain faces diverse types of risks, each with varying degrees of impact. In managing these risks, Winbond employs a four-step approach aimed at achieving optimal costs and minimizing impacts.

  • First, Winbond monitors and assesses impacts using the systematic thinking of ISO 31000 risk management.

  • Second, identify and categorize the types and sources of risks, distinguishing between Internal Risk, Intra-partnership Risk, and External Risk.

  • Third, establish corresponding preventive mechanisms in response to the types and sources of risks.

  • Fourth, review each management event and improve based on identified deficiencies to mitigate the impact of future risks on supply chain operations, ensuring continuous improvement and preventive capabilities.




Material Risk

  • Winbond regards the Responsible Business Alliance (RBA) requirements for conflict-free minerals as a core management principle. Annually, Winbond conducts due diligence investigations on critical suppliers using the Conflict Minerals Reporting Template (CMRT) provided by the Responsible Minerals Initiative (RMI) and publishes an annual Conflict Minerals Due Diligence Report.
  • To uphold product quality, Winbond has established the Process/Product Change Notice (PCN) management principle for suppliers. This management mechanism is activated whenever there is any change in raw materials or in suppliers’ raw material, process, or packaging materials.


Intra-partnership Risk

  • Require newly qualified suppliers to sign Winbond's Supplier Code of Conduct  Commitment Letter.
  • Conduct biannual ethics and integrity policy advocacy for all suppliers.
  • Declare Winbond's information security management policy and intellectual property rights policy within the order, requiring suppliers to strictly adhere to confidentiality obligations arising from the transaction relationship.
  • Specify in the order the measures and compensation responsibilities for both parties in the event of the aforementioned risks.


External Risk

  • In the event of natural disasters such as earthquakes, Winbond utilizes its Emergency Response System to promptly reflect seismic intensity worldwide, allowing procurement colleagues to assess the impact on suppliers.
  • In controlling the impact of climate change, Winbond has analyzed the disaster potential of more than 1,400 domestic suppliers at their operating sites according to various warming scenarios.
  • Regarding political-economic risks (e.g., Russia-Ukraine and Israel wars) and social risks (e.g., supplier factory safety accidents, strikes) that may cause supply disruptions, Winbond promptly establishes an emergency response team to manage situation reporting, compilation, notification, analysis, and assessment.
  • Winbond strictly adheres to the regulations of the Customs Administration, Ministry of Finance, regarding "Authorized Economic Operator" (AEO) status, and requires contractors to comply with and improve trade security  management.
  • Winbond strictly adheres to the Ministry of Economic Affairs' International Trade Administration's Internal Compliance Program (ICP) to prevent inadvertent export of its products to entities posing risks related to weapons proliferation.

Mitigation and adaptation measures for supply chain climate risks

Winbond, as a semiconductor manufacturer, faces potential severe impacts on operational and financial fronts from natural disasters, accidents, human errors, changes in international political and economic situations, emergence of new technologies, and regulatory changes. Suppliers are critical partners in Winbond's operations, and their ability to adapt to climate risks is naturally a key success factor in advancing supply chain sustainability efforts. Through regular climate-related financial disclosures, Winbond identifies climate risks and opportunities. In 2023, a total of 14 climate risks and 12 climate opportunities were identified. Immediate impacts were identified on suppliers' operations, particularly in energy and water management. Currently, ongoing efforts include regular assessments to monitor first-tier suppliers' actions in energy and water resource management, and encouraging waste reduction and management within their existing operational frameworks.

Sustainable risk Due Diligence in the supply chain

In recent years, significant occurrences of extreme weather events, unpredictable fluctuations in global health crises, and geopolitical conflicts have led to rapid shifts in various industry landscapes. This has highlighted the importance of maintaining resilience within supply chains and strengthening adaptive capabilities to manage diverse disasters and changes. These capabilities have become a core focus in corporate management.

To effectively ensure and support suppliers in their sustainable journey, Winbond conducts regular due diligence investigations on sustainability risks among suppliers. This helps in identifying the types and impacts of risks across the supply chain, and in planning improvement strategies to ensure stability, quality, and reliability of supply.

Sustainability risk due diligence process

Winbond has four major steps to implement supply chain sustainability risks.

  • First, we use the RBA Code of Conduct, ISO 20400 Sustainable Procurement Guidelines, and PAS7000 Supply Chain Risk Management to establish due diligence content, and regularly classify and target annual transaction suppliers. First-level key suppliers proactively issue surveys.

    • First-tier key supplier identification criteria:

      • Directly related to manufacturing

      • The first 85% of the purchase amount of this type

      • Single source

      • For spare parts that are critical and affect production (photo masks, PAD, quartz, packaging materials for shipment)

    • In 2023, there will be a total of 1,027 annual transaction suppliers, of which a total of 69 first-level key suppliers that meet the identification criteria, and In terms of purchase amount, the proportion is approximately 24%.

  • Second, issue surveys, track suppliers’ filling status, and provide explanations and assistance as needed.

  • Third, after the investigation and recovery, the sustainability evaluation and audit work will be started. In the written audit, the documents attached by the supplier will be comprehensively reviewed based on the environmental aspect (E), social aspect (S), and governance aspect (G). The degree of compliance with the scoring content identifies suppliers with negative impacts. Among them, those whose average score does not reach 80 points are listed as key suppliers, and the suppliers are notified to conduct on-site audits, on-site visits and inspections, to understand the reasons for the negative impact.

  • Fourth, concentrate coaching resources to require high-risk suppliers to improve their deficiencies; at the same time, observe the operational resource status of high-risk suppliers and match coaching resources to intervene to reduce their transformation burden.



Content of supplier ESG risk assessments

Winbond utilizes the Responsible Business Alliance (RBA) Code of Conduct, ISO 20400 Sustainable Procurement Guidelines, and PAS7000 Supply Chain Risk Management to establish due diligence frameworks. The approach includes:


  • Environmental considerations and protection aligned with the Eco-Management and Audit Scheme (EMAS) within the core of the RBA framework.
  • Human rights assessments referencing the OECD Guidelines for Multinational Enterprises, UN Guiding Principles on Business and Human Rights, UN Universal Declaration of Human Rights, ILO Declaration of Fundamental Principles and Rights at Work, and ILO Fundamental Conventions.
  • Governance aspects incorporating Social Accountability International (SAI, SA8000) standards and the UN Convention against Corruption.

These frameworks collectively form the basis for Winbond's Supplier Code of Conduct and Winbond Sustainability Assessment Questionnaire (SAQ), ensuring comprehensive evaluations and commitments to sustainability and responsible business practices throughout its supply chain.

Supply chain sustainability risk due diligence results

In 2023, Winbond proactively conducted surveys among key first-tier suppliers, achieving a response rate of over 90%. Among these suppliers, the overall ESG (Environmental, Social, and Governance) average score was 84.2. High-performing groups included international raw material suppliers and outsourced packaging and testing contractors.

Further observations across specific categories revealed strong performances in service quality management, occupational health and safety, human rights, and labor guarantees, with average scores ranging from 92 to 95. However, for enhancing overall supply chain resilience, suppliers need to improve formalization of corporate sustainability practices, such as formal organizational structures and management systems. Environmental adaptation and protection efforts, particularly in greenhouse gas management, biodiversity, and resource recycling, also require strengthening.


  • Regularly survey, evaluate, and identify key risks and their impact levels in the supply chain.
  • Conduct written audits based on ESG criteria to identify key focus suppliers among first-tier critical suppliers.
  • Perform on-site audits of key focus suppliers to identify high-risk categories and assess impact levels.
  • Provide suppliers with improvement recommendations and appropriate resources.
  • Mitigate concerns about the expansion of risk impacts.
