ENEOS has established quality assurance procedures for quality assurance systems and operations covering all of our products and services.
In addition, all ENEOS refineries and plants have obtained ISO 9001 certification.
Furthermore, we have developed a proprietary Quality Management System that is specifically focused on requirements for managing the quality of petroleum and petrochemical products, based on ISO 9001. We have implemented this system at all of our refineries and plants, and are carrying out activities to expand it throughout the supply chain.
One of the features of this system is the performance of quality management risk assessments and risk reduction measures to prevent quality-related issues from occurring. Employees learn quality management risk analysis methods, enabling them to identify risks and take appropriate measures to address them, thus contributing to the achievement of proactive, highly effective quality management.
For product quality design and the establishment of manufacturing standards, in addition to fulfilling legal requirements, standard specifications such as those prescribed by JIS, and the contractual requirements of customers, we have developed an extensive database of our abundant experience and knowledge, thus giving due consideration to the prevention of issues in the use of our products by customers and providing reliable, high-quality products.

Information about quality complaints and issues that have occurred at ENEOS refineries and plants is shared via databases with other refineries and plants, and company-wide measures to prevent recurrence are discussed and implemented, thus contributing to the future prevention of quality-related issues.

ENEOS carries out inspections of the quality management systems of its refineries and plants based on the Quality Management System. These inspection activities include internal audits conducted by each plant or refinery and audits implemented by the head office Quality Assurance Department. Inspections identify the strengths and weaknesses of each location, and the results are shared throughout the company, enabling us to strengthen the quality management systems at each site and make further improvements to the Quality Management System.
In the inspection activities conducted in fiscal 2022, we found no irregularities, including irregularities in terms of information and labeling, in product safety and quality in fiscal 2022. We will continue to strengthen our quality assurance systems by utilizing and improving upon the Quality Management System.

At ENEOS, in accordance with company procedures, each department conducts self-audits, while independent departments that supervise and manage quality assurance perform quality audits. In this way, we conduct regular audits of the quality control work and activities for the products and services of each department. Through these efforts, we strive to properly maintain and manage the quality of products and services while carrying out continuous improvement.
JX Metals has developed an internal quality audit program based on guidelines for conducting internal quality audits and in accordance with management needs and risks. Through this program, the Quality Control Department conducts quality control inspections and each site conducts voluntary inspections. The results of internal quality audits are analyzed and reported to the Quality Management Meeting, which is made up of top management, and are reflected in the continuous improvement of the quality management system.

ENEOS systematically conducts training for each department on matters necessary to ensure the quality of its products and services and their continuous improvement, and also provides training on laws, regulations, contracts and internal rules. It also holds training sessions for quality assurance personnel and in-house seminars with highly specialized content, such as compliance with laws and regulations related to chemical substance management, to help promote quality assurance activities.
The JX Metals Group is thoroughly disseminating its Basic Quality Policy through e-learning and other means. It also provides quality control training for all employees to raise the level of quality control. For this quality control training, JX Metals has prepared various training programs, which range from introductory courses to advanced courses according to the level of the participants, and which employees are encouraged to take systematically according to job function and year of employment. These programs have become an established part of employee training.
