Procurement

The Company will promote material procurement activities based on the following three basic polices:

In September 2025, in response to revisions of the Basic Procurement Policy, the Group established Sustainable Procurement Guidelines for the Mitsubishi Steel Group. These Guidelines clarify the thinking and guidelines essential to sustainable procurement activities in areas including equitable and fair business, compliance, the environment, human rights, and health and safety, for all suppliers who do business with the Mitsubishi Steel Group. They set as goals growth and progress alongside our suppliers by partnering with them based on trust and mutual efforts.

In support of the aims of the Council on Promoting Partnership Building for Cultivating the Future under the Cabinet Office, the Small and Medium Enterprise Agency, and others, we have announced our Declaration of Partnership Building. We plan to build new partnerships by promoting cooperation, coexistence, and co-prosperity with members of our supply chain and the other businesses with whom we create value.

We undertake CSR surveys throughout our supply chain, including our business partners. To help them better understand our procurement policies, we ask business partners to participate in surveys on CSR procurement. Results of CSR surveys are provided to suppliers and briefings are held on new social issues and other matters to gain their understanding of our business activities.

Recognizing human rights as an important social issue, we undertake human rights due diligence to identify human rights risks in our business activities and supply chain. In FY2024, we surveyed suppliers of melting materials, spring materials, auxiliary materials, refractories, and other important supplies. No serious violations were identified.We will continue to identify and assess human rights risks in our business activities and promote business activities that account for human rights.

To protect the earth's environment by reducing CO₂ emissions and other measures, we prioritize use of recycled and eco-friendly products. We also actively seek out proposals for products and services that contribute to environmental conservation activities. We partner with business partners and other stakeholders to prevent use of conflict minerals that might fund armed forces and foster human rights abuses and conflict.

Conflict minerals refer to the four minerals of tin, tantalum, tungsten, and gold sourced from the Democratic Republic of the Congo and nine neighboring countries. There are concerns that sales of these minerals play a role in human rights violations, armed conflict, and funding for military actions.
We investigate whether suppliers use conflict minerals. As requested by customers, we also use the investigation template issued by the Responsible Minerals Initiative (RMI) to report that products are free of conflict minerals.
