This policy applies to all subsidiaries and facilities of the Mitsui Kinzoku group worldwide.
Strengthening of the quality assurance system
To strengthen the quality assurance system, Mitsui Kinzoku Group established the Quality Assurance Department on March 20, 2018. In addition, in order to strengthen quality assurance functions, we have promoted the independence of quality assurance departments in each business line, and have completed the construction of systems in all business divisions.
The Quality Assurance Department at the head office and the Technical Department and Quality Assurance Department of each business division make up the Quality Assurance Committee, which promotes planning and implementation of strengthening the quality assurance system.
