Establishing and Operating a Quality Management System
The Group established a quality management system (QMS), which we operate to carry out our Basic
Quality Policy. We work to continually make quality improvements through steady PDCA cycles, aiming to
realize better quality through the QMS. As one measure, Company sites both in Japan and overseas have
acquired QMS third-party certification (ISO 9001, etc.).
In addition, the Group reviews quality improvement activities and establishes action plans through the
Quality Management Meeting, which is attended by top management. We also hold meetings with the
persons in charge of quality twice annually to share information on quality management. Participants
share the action plans adopted at Quality Management Meetings and share issues encountered and good
practices found at each manufacturing site, fostering interactions among managers. Furthermore, we are
working to improve the effectiveness of internal quality audits, automate inspections, and strengthen
the training of quality control personnel.
Our efforts to strengthen human resources development included introducing the OEA Program offered by
the International Register of Certificated Auditors (IRCA). This program is the only system in the
world on its kind, designed to train quality audit professionals to meet global standards. The JX
Advanced Metals Group focuses on improving our quality management system (QMS), not only for product
quality, but also across all business processes, placing importance on internal audit effectiveness.
We aim to double our number of professional quality auditors through the OEA Program by 2027.
Currently, we have a total of 11 employees evaluated by and registered with IRCA under its
international standards, including 2 Lead Auditors, 2 Auditors, 4 Internal Auditors, and 3 Associate
Auditors. We define those working as Auditors or higher-level positions as Professional Quality
Auditors.
These initiatives support the JX Advanced Metals Group long-term vision to become a global leader in
advanced materials. We will continue to improve our QMS to help drive innovation and contribute to
social progress.

Quality Management Department Activities
The Quality Management Department is in charge of planning, proposal, promotion, and oversight for enhancement of Group-wide quality control. This department is also engaged in clarifying Group-wide QMS requirements, improving the effectiveness of internal quality audits, supporting quality improvement activities and quality control training at manufacturing sites, introducing DX to quality management tasks.
Liability Claims
In fiscal 2024, no claims were pursued under the Product Liability Act due to personal or property damage caused by defects in products made by Group companies.
Providing Information on Products and Services
In accordance with the Basic Quality Policy, the Group provides customers with information on our products and services through product specifications and Safety Data Sheets (SDS)*. For example, sulfuric acid sold by Group companies is designated as a deleterious substance under Japan's Poisonous and Deleterious Substances Control Act. By limiting our business partners to sellers of poisonous or deleterious substances and issuing SDSs, we strive to prevent serious negative effects on the occupational health and safety for our customers and their employees after delivery.

Initiatives With Suppliers
Cooperation with suppliers is essential for thorough quality assurance. Our efforts include conducting regular evaluations and quality audits for JX Advanced Metals Group suppliers based on quality control criteria and requirements, reducing quality risks, and improving the quality level of our suppliers. We also conduct Supplier Questionnaire to promote mutual understanding with our suppliers.
Promotion of Personnel Quality Education
The Group ensures that all employees are thoroughly familiar with the Basic Quality Policy through
quality control training. In addition, we provide quality control training to all employees to improve
their problem identification and resolution capability, help them to logically infer the root cause of a
problem, independently resolve problems, and improve the quality of their work. These training programs
range from introductory to advanced courses according to the level of the participants. The programs
reflect carefully planned courses according to job rank and years of employment, and have become an
established part of employee training.
A total of 513 employees completed quality control training in fiscal year 2024. In fiscal year 2025, we
aim to train over 500 employees, further strengthening our commitment to talent development.
