with Customers

Our basic thinking on quality

Cosel has established the quality policy "Creating customer confidence through our products and services." based on our management philosophy (organizational goal) of "Responding to the Trust of Society by Putting Quality as the Most Important Priority."
The bases of quality activities are product reliability and delivery of peace of mind to customers. We believe that these will enable us to earn the trust of society.
To realize this policy, we have identified the concept of total quality management (TQM) as a pillar of management, and we aim to link this concept to our sustained growth as an enterprise through raising the levels of quality of not only our products and services but also our work and our management.
Cosel will strive to improve quality at all stages from product planning and development through production, sales, and service, in order to provide our customers with attractive products and services that win their trust and deliver peace of mind and satisfaction.

ISO 9001 certification

We were the first company in Toyama Prefecture to earn ISO 9001 international certification through establishing a quality management system, and we continue to implement thorough quality management.
We began application of the FY 2015 version of ISO 9001 in October 2016. We successfully acquired certification under the FY 2015 version following a transition audit in June 2017, and we have maintained this certification ever since.
We will continue striving to improve quality further and increase customer satisfaction.
