Strengthen Restricted and Hazardous Substances Management

E Ink is committed to providing products that meet customer needs while being environmentally friendly, adhering to the management principles of "No Entry, No Use, No Output" for hazardous substances. Strict controls are implemented at every stage, from product design, raw material procurement, and manufacturing to production testing and final sales, ensuring compliance with current domestic and international regulations and commitments on hazardous substance management. E Ink currently manages restricted substances in accordance with the Restriction of Hazardous Substances Directive (RoHS), the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH), the prohibition of conflict minerals, Halogen Free , and the European Union's Waste Electrical and Electronic Equipment (WEEE) directive. No noncompliance issues were identified in 2024. Additionally, E Ink incorporates specific customers' restricted substance regulations into its controlled substance list after thorough review to further strengthen management. In 2025, E Ink plans to incorporate Persistent Organic Pollutants (POPs) and Per- and Polyfluoroalkyl Substances (PFAS) into its management scope and will continue to monitor key restricted substance regulations in its product markets to ensure compliance with the latest environmental regulations and customer requirements.


In 2021, E Ink's "Environmental Restricted Substances Management Committee" established the "Green Product" management guidelines, implementing comprehensive control over all components through the restricted and hazardous substances management process. In addition to regularly holding meetings and reviewing operations to ensure that management standards remain up-to-date, the committee also evaluates customer requests or changes in international restricted and hazardous substance regulations, adjusting control standards and operational modes as needed, and notifying relevant departments through announcements. If restricted substances are found in products, a phased-out or substitution will be developed.

E Ink requires suppliers to provide a list of controlled substances and related information, and confirm their commitment not to use such restricted and hazardous substances in the form of a declaration. If the raw materials provided by the supplier contain restricted and hazardous environmental substances or conflict minerals, they will bear corresponding compensation responsibilities. As of 2024, E Ink has engaged 187 suppliers for controlled substances, all of whom provide qualified raw materials, and no legal violations related to products have occurred.


Plastics and metals used in products

In 2022, during the UN Environment Assembly, 170 countries committed to establishing a binding global agreement, the Global Plastics Treaty, to regulate the production, use, and disposal of plastics in industries that heavily rely on plastic products. This convention has been recognized as one of the most significant global environmental agreements since the 2015 Paris Climate Agreement. Plastics have garnered widespread attention because, once they enter the oceans, they not only cause the death of marine life and destruction of habitats, but larger plastics also gradually break down into microplastics that are absorbed by marine organisms and enter the food chain, ultimately posing potential risks to human health.


Moreover, with the rapid advancement of technology and the transition of traditional industries to clean energy technologies, the demand for metal resources across various sectors continues to grow. The International Energy Agency (IEA) said that "since 2010 the average amount of minerals needed for a new unit of power generation capacity has increased by 50% as the share of renewables in new investment has risen." However, metal extraction is highly associated with child labor, forced labor, damage from hazardous materials or chemicals degradation of biodiversity, or high CO2 emissions. Therefore, promoting the use of recycled metals has become imperative.


Metals and plastics are indispensable raw materials in the production of E Ink products. To reduce the environmental and social impacts caused by the use of these raw materials in the manufacturing process, E Ink began an inventory of the metals and plastics used in its productsNote in 2024, laying the groundwork for increasing the use of recycled materials in the future. Through these efforts, E Ink is committed to achieving more sustainable product design and production processes, reducing negative impacts on the environment and society, and advancing the development of green products.


Note: The inventory focuses on products and modules that account for 80% of the shipping weight in 2024.
