Sony GP Certificate

The Company's Hsinchu Site has been certified by the quality-related system certifications including ISO 9001, SONY GP, and Amazon. The site has also been certified by the customer audits. A quality management system has been set up based on the relevant principles, and with the PDCA cycle of the management system, the customers have visited the production site for onsite process audits to ensure that the product quality and commitment satisfy customer requirements. E Ink has received several customer acknowledgments and recognitions for our product quality. Starting from 2018, our Hsinchu Site, Linkou Site, and Yangzhou Site have all received the Grade-A Supplier distinction from our key customer, SONY Green Partner. Not only that, the Company has passed subsequent quality audits to preserve this distinction in 2021; the certification is valid through 2024.


After establishing quality policies and objectives concerning the framework of these QMSes, we implemented them throughout the organization for all employees to understand and follow the relevant

regulations in order to provide customers with quality products and services.
