Quality Control and Quality Assurance

Commitment to Quality Management and Quality Assurance Initiatives

Initiatives to Ensure Product Safety

We conduct checks of product safety at each product stage, from research and development through sales based on Rule for the Product Safety. Regulations of various countries concerning chemical substances have been frequently changing, and it is essential to respond swiftly and decisively to these changes. In FY2017, we introduced a new tool aimed at better managing information on the hazardous properties of chemical substances used in our products. Having expanded the scope of departments subject to chemical information management, we have successfully responded to domestic and overseas regulations, which are evolving frequently.

Response to Complaints on Quality

In the unlikely event of serious product safety or quality issues, we follow the “Crisis Response Rules” to minimize damage and any impact on society at large. The Customer Relations Center receives quality-related complaints and inquiries and, depending on the content, works with relevant departments to provide a swift response. We had no serious quality incidents requiring company-wide response during FY2019.

Providing Appropriate Product Safety Disclosure and Labeling

We issue safety data sheets (SDS) for the products it manufactures as stipulated under the relevant laws. Each product bears labeling that indicates its hazardous properties and safety-related details in accordance with chemical classification that complies with the GHS (Globally Harmonized System of Classification and Labelling of Chemicals). Product safety information is also available via Idemitsu’s website as it is equipped with a system that enables users to search product data by name or usage.

Employee Education and Awareness Raising Regarding Quality

The Idemitsu Group conducts education and awareness raising activities aimed at increasing employees’ awareness of quality. Specifically, we hold workshops for managers in charge of quality to empower them to promote quality assurance activities at their respective divisions or affiliates, as well as internal seminars on such highly specialized topics as responding to laws and regulations on chemical substance management. Such activities help us advance quality assurance activities across the Group. Furthermore, every November, we conduct Quality Month events, holding lectures on quality, soliciting quality slogans, and putting up posters to inspire each and every employee to think about quality (in FY2020, lectures were cancelled to prevent the spread of COVID-19).
