The Optex supply chain extends throughout the world. We have built a seamless supply chain consisting of a series of activities, through which we can stably source reliable raw materials, carry out planned production, and use logistics to steadily and speedily deliver high-quality products to customers in over 80 countries around the world.

Minerals mined in the Democratic Republic of the Congo and neighboring countries and conflict-affected and high-risk areas (CAHRAs) are not only a source of human rights violations such as child labor and environmental destruction, but also a source of funding for armed groups and are feared to contribute to conflict itself. In order to reduce the risks of sourcing these minerals and ensure more responsible sourcing, we will implement the following initiatives based on the OECD Due Diligence Guidance.

- We will explain our policy to our suppliers and conduct a supply chain investigation.
In the investigation, we will use standardized templates such as the CMRT (Conflict Minerals Reporting Template), a tool provided
by the RMI (Responsible Minerals Initiative), to understand the supply chain.

- We will encourage our suppliers to procure from smelters certified by third-party organizations such as RMI, and to change suppliers or transition to lower-risk sources if high risk is suspected.
In FY2024, we received responses for 86% of the items surveyed from our suppliers. As a result of the survey, we confirmed that 230 smelters in our supply chain are RMI certified.
