Supply Chain Management

WNC considers supplier management to be one of its most effective tools for promoting social responsibility. In addition to requiring suppliers to enhance their performance on quality, delivery, service, and price, WNC also works with suppliers in the implementation of P-D-C-A (Plan-Do-Check-Action) improvement cycles to realize the sustainability of our supply chains, and formulates the WNC Supplier Code of Conduct in accordance with the Responsible Business Alliance (RBA, formally the Electronic Industry Citizenship Coalition (EICC)) Code of Conduct. WNC also activates a supplier corporate social responsibility audit plan (Supplier CSR Audit).

Supplier Code of Conduct


WNC Prohibition of Conflict Minerals Policy

  • No product shall use ores from the DRC and illegal mines in the surrounding area as well as those mined in poor working conditions.
  • Require suppliers to ban the use of conflict minerals and disclose their sources for Tin (Sn), Tungsten (W), Tantalum (Ta), and Gold (Au) ore.
  • Suppliers are asked to convey this policy to their own upstream suppliers and supply chain.

CSR Audit

In October 2013, WNC officially launched its supplier corporate social responsibility audit (hereinafter referred to as the “supplier CSR audit”) program, in which different types of major suppliers are divided into A (high risk), B (moderate risk) and C (low risk) according to the level of risk they exhibit in aspects of labor, ethics, health and safety, and environment and management systems. With the exception of certain suppliers named by customers, Group C suppliers are only subject to document review given the low level of risks they exhibit, while the other two groups of suppliers must undergo supplier CSR audits according to the following the four steps and be assessed on aspects of labor, ethics, health and safety, environment, and management systems.


Customer Relations

Customer Focus has always been one of WNC’s core values, and we strive to provide the best service to our customers. WNC’s Customer Service Section is managed by the Quality Assurance Division and is responsible for customer-service tasks, which include Dead on Arrival (DOA), Return of Materials Authorization (RMA), sales of repaired parts, customer complaint handling and reporting, as well as the annual customer satisfaction survey.

Each business unit, the quality assurance group, R&D, production planning, and manufacturing units are designated as the point-of-contact for different customers. According to project needs, each unit and their respective customers participate in weekly and monthly meetings to review product development progress and each item’s achievement rate. Each unit also appoints representative to participate in the quarterly supplier business review meeting with their respective customer to immediately communicate and build mutual trust.


Contractor Health and Safety Management

WNC has drawn up a Contractor EHS Management Procedure to ensure the safety of both contractors and WNC employees and maintain facility safety and observe related labor health and safety regulations. This document clearly demarcates the powers and responsibilities of company units and contractors and describes EHS issues requiring attention.
