Research conducted by the Responsible Minerals Initiative (RMI) discovered that the rebel groups in the Democratic Republic of Congo and neighboring countries in Central Africa use forced labor, child labor, and other illegal means to mine tungsten, tin, tantalum, gold, cobalt, and mica, and sell them in exchange for weapons, thereby causing regional instability. Minerals obtained through illegal means are referred to as conflict minerals. Tungsten, tin, tantalum, gold, cobalt, and mica are essential for electronic products to function. To avoid the use of conflict minerals obtained from illegal operations, we have established the Responsible Raw Materials Procurement Policy and the Due Diligence Investigation on Conflict Minerals of Suppliers. Please refer to the "Delta Group Responsible Sourcing Policy” section of our website for more information.
To ensure that no conflict minerals are used in Delta products, Delta examines product ingredients and identifies suppliers that require investigation every year. In 2024, 2,525 suppliers are included. Delta conducts due diligence investigations using an online questionnaire converted from the CMRT 6.4, EMRT 1.3, and the AMRT 1.2 template* to comprehensively check the distribution and compliance of the refineries used by suppliers. We also strengthen communication and cooperation with suppliers through webinars to practice responsible manufacturing. Delta requires suppliers to disclose and purchase minerals from qualified refineries based on the latest list of valid and qualified refineries published by the Responsible Minerals Initiative (RMI).
According to the investigation, Delta's supply chain sourced materials come from 267 refineries as of the end of 2024, all of which were included in the most recently updated list of qualified refineries. Further analysis showed that Asia had the highest number of qualified refineries, followed by Europe.
