Mitsui Chemicals


The Mitsui Chemicals Group is providing products and services that foster the satisfaction while responding to the trust of customers by continually improving the level of its quality management based on the Responsible Care Policy.

Management System


Under our Responsible Care Policy, we have identified details of our quality structure and other key issues such as PDCA procedures as basic matters concerning quality management in our internal regulations. In carrying out the appropriate procedures, we are providing products and services that foster the satisfaction and trust of customers.

In conjunction with the global expansion of the Group’s business, we have identified specific principles for global quality management in order to ensure a uniform awareness toward the basic level of quality. Steps are being taken to roll out these principles across the Group as a whole.

Quality Management System and Responsible Officers

Monitoring Methods

Quality management:

Steps are taken to identify quality audit program and priority audit items and to confirm the status of quality management implementation across the Group as a whole. A review of certain items including observations raised during fiscal year-end audits is undertaken. The results of this review are reflected in the audit program for the following fiscal year.

Quality of Products:

In addition to systematically collating customer complaints, steps are taken to monitor the details, causes, and each customer’s response with respect to each complaint. After analyzing the information gleaned on a monthly basis, the results are shared within the Group. After conducting a review of complaints over the year, quality targets are identified for the following fiscal year.

Achievements and Reviews:

Quality complaints also remained at record low levels in fiscal 2016. This reflects successful efforts to uncover the underlying cause of each complaint and measures aimed at preventing any recurrence promoted horizontally across the Group.
In addition, considerable emphasis is placed on nurturing increased awareness toward quality within the Mitsui Chemicals Group through explanations of the Global Quality Management Principles put in place in 2015 during audits and training sessions.
Looking ahead, and amid the growing trend toward globalization and increased product performance, every effort will be made to further raise awareness toward quality and to address the critical need for an increasingly customer-oriented and sophisticated quality management system.
