Quality Management

Chapter 2 of the Cosmo Energy Group Code of Conduct states, “We live up to customer expectations concerning reliability and satisfaction.” It is our mission to deliver products and services that meet customer expectations concerning reliability and satisfaction in a stable manner. Our Quality Policy sets out our fundamental approach to quality, based on our Code of Conduct, which states that we actively and continuously strive to maintain the quality and ensure the safety of our products and services.

The Cosmo Energy Group engages in quality assurance activities to maintain and improve the quality of products and services that fulfill customer needs. We have introduced a quality management system in our manufacturing departments and plants to ensure the quality of the products and services we provide. We have obtained ISO 9001 certification at eight of our refineries and plants. In addition to conducting internal audits, we undergo external inspections to verify the implementation of initiatives to maintain quality and ensure safety, as well as legal compliance.

Ensuring the Reliability of Petroleum Products

Based on the Cosmo Energy Group’s Quality Policy, the Sustainability Strategy Committee at Cosmo Energy Holdings sets quality targets for the entire Group. Cosmo Oil also has a Sustainability Promotion Committee, which determines quality assurance policies and promotes activities in line with Group quality targets.

 

In fiscal 2022, we made the prevention of serious product (quality) accidents a KPI and stepped up our quality control activities. Our refineries and plants continued to maintain a record of zero serious quality-related issues and shipments of non-conforming products.

 

Cosmo Oil and Cosmo Oil Marketing have established committees related to quality assurance to decide on quality assurance policy and promote activities in order to provide safe products that meet the quality requirements of customers in an economical, stable manner. The committees of the two companies work with the Sustainability Strategy Committee at Cosmo Energy Holdings, forming the Group quality assurance structure.
