CSR Audits

WNC has formulated a WNC Supplier Code of Conduct and requires that all suppliers sign the Supplier CSR Declaration and the Supplier’s Commitment to the Code of Ethics, in which they declare their commitment to fulfilling social responsibilities, promise to ban child labor and forced labor, implement occupational safety and health management, fight against bribery and corruption, promote fair trade, and support employees’ freedom of association and bargaining rights with management. WNC also requests that suppliers fill out the WNC Supplier CSR Questionnaire to state their implementation results in the areas of labor, health and safety, environmental protection, business ethics, and management systems.

WNC Suppliers CSR Audit Measures

WNC’s major suppliers are divided into A (high risk: suppliers of printed circuit boards, paint, plastic injection parts, chemical plating, and stamped parts), B (moderate risk: suppliers of antennas, packing materials, wiring, adapters, connectors, and passive elements) and C (low risk: suppliers of other electronic materials) according to the level of risk they exhibit in aspects of labor, ethics, health and safety, and environment and management systems. Further, WNC requests that selected suppliers conduct a CSR audit based on conditions including “Top 10 suppliers in terms of incoming quantities in the previous year which were not audited in the past year;” “complying with customers’ CSR requests;” and “Had priority deficiencies in the previous year’s audit,” and includes them in the annual CSR audit scheme. With the exception of specific suppliers designated by customers, Group C suppliers are only subject to document review given the low level of risk they exhibit, while the other two groups of suppliers must undergo supplier CSR audits according to the following five aspects of labor, ethics, health and safety, environment, ethics and management systems of the RBA Code of Conduct.

Prohibition of Conflict Minerals

WNC does not directly purchase raw metal materials, and has a declared policy to ban the use of conflict minerals. WNC supports the Responsible Minerals Initiative (RMI) that was jointly initiated by the RBA and the Global e-Sustainability Initiative (GeSI), adopts the Conflict Minerals Reporting Template (CMRT) stipulated to conduct conflict minerals investigations for suppliers every year since 2010, and identifies supplier risk levels based on the investigation results in accordance with WNC’s conflict minerals management procedure.
