Quality management is one of the most important aspects in obtaining the trust and satisfaction of customers in the provision of products and services. All of our relevant employees are responsible for thorough quality management. In coordination with product units and individual steelworks, the Company’s Quality Assurance Department promotes measures to cope with Groupwide quality control and assurance issues.

Activities aimed at strengthening the quality assurance system of the Nippon Steel Group

As a basic policy in line with the Japan Iron and Steel Federation’s guideline, aimed at strengthening the quality assurance system, we are promoting

• the enhancement of education on quality compliance (compliance with laws and regulations)
• activities to reduce behavioral risks, and
• advanced internal quality audit. Information on quality

related examples is promptly shared across the Group and at appropriate times measures are launched to resolve issues through standardization, systemization, automatization, and other action.

These measures are then implemented to enhance identification management of actual products and to improve reliability of testing and inspection.
