Global Supply-Chain Management Policy


WNC and our suppliers work hand in hand to maintain a sustainable supply chain through continuous optimization of supplier-management strategies and of operations efficiency. This facilitates balanced growth of operating profits, while protecting the environment and fulfilling social responsibilities, in order to realize increased value for all stakeholders.

Mission Statement

Based on the principles of supporting business development and improving competitiveness, WNC will continue to effectively manage and enhance our suppliers’ performance in: quality, price, lead-time, services, environmental protection, and fulfillment of their social responsibilities. This enables us to develop an optimal supplier portfolio and purchasing guidelines, contributing to a responsible supply chain jointly managed by WNC and our suppliers.

Local Sourcing

Based on calculating the purchase amount of raw materials and components from different regions, WNC’s main suppliers were from Taiwan, accounting for 42% of the total in 2017, while suppliers from mainland China accounted for approximate 25%. Major categories of supplied raw materials and components include integrated circuits, circuit boards, display panels, electromechanical components, mechanical components and packaging materials. The other suppliers are located in Asia, Europe and the U.S.

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 value, WNC also works with suppliers in the implementation of P-D-C-A (Plan-Do-Check-Action) improvement cycles to achieve sustainable supply chains. WNC has also formulated the WNC Supplier Code of Conduct in accordance with the Responsible Business Alliance (RBA, formally the Electronic Industry Citizenship Coalition (EICC)) Code of Conduct and established a supplier corporate social responsibility audit plan (Supplier CSR Audit).

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 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. Pertinent business groups or units, the quality assurance group, R&D, production planning, and manufacturing units are designated as the point-of-contact for each different customer. According to project needs, customers and pertinent point(s)-of-contact participate in weekly and monthly meetings to review product development progress and each item’s achievement rate. Each business group/unit, also appoints representatives to participate in a 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, 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 ESH issues requiring attention.
