Management System

Policy and Basic Approach

The Mitsui Chemicals Group is taking a two-pronged approach in quality management, based on quality control and quality assurance, to bring management levels higher than ever across the supply chain. We aim to offer products and services that fully satisfy our customers, gaining their trust through quality compliance reinforcement, quality risk reduction, and human resources development that underlies our quality management.

Under our Responsible Care Policy, we have identified details of our quality system and other key issues such as PDCA procedures as basic matters concerning quality management in our internal regulations. 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.

Business divisions, the Logistics and Purchasing divisions, Works, and laboratories are responsible for quality control. The RC & Quality Assurance Division is responsible for quality assurance. As the heads of each division, general managers engage in quality management.
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.

These complaints were eventually consolidated by promptly reporting the causes and implementing recurrence prevention measures.
