In order to establish a more resilient and sustainable supply chain, Winbond has proactively promoted corporate sustainable development by broadening the scope of these efforts. For pursuring a long-term and sustainable partnerships with our suppliers, we also hope to attract potential suppliers who share the same vision of sustainable business operations with us. By implementing sustainable supply chain management policies, and collaborating on regular ESG supplier workshops, environmental conservation investigations, and supplier sustainability training courses, we are truly appreciated to embed sustainability elements into Winbond’s sustainable supply chain management system gradually.

Conflict Minerals

Conflict Minerals

Following the provisions on conflict minerals in the Responsible Business Alliance’s Code of Conduct, Winbond does not procure or utilize any minerals sourced from regions of the Democratic Republic of the Congo which are under the control of non-government or unlawful military groups. Prohibited minerals include gold (Au), silver (Ta), tantalum (Ta), Tungsten (W), and Tin (Sn). 100% of our main suppliers have signed the Winbond Supplier Code of Conduct Commitment Letter.Winbond have also formally announced to our suppliers our policy of not using conflict minerals through public declarations on our official website and advocacy letters.

Winbond has also used the Conflict Minerals Reporting Template (CMRT Ver. 6.22) according to the RBA Code of Conduct to investigate the use of conflict minerals by suppliers. Winbond have requested suppliers to disclose information on smelters which process conflict minerals, and taken action to ensure that information provided from suppliers is accurate. In the future, Winbond shall continue to cooperate with its suppliers to ensure that all suppliers use materials from Tier 1 Conflict-Free Smelters certified and announced in the RBA Code of Conduct as smelters which do not use any conflict minerals. Winbond conducted an investigation into conflict minerals for 18 of our suppliers (9 raw materials suppliers and 9 outsourcers). All of these suppliers were found to be compliant with related rules. In 2022, no products were prohibited from being sold to Winbond.
