Quality Assurance

Ensuring Provision of Safe Products

Basic Stance

The Teijin Group conducts product liability/quality assurance activities under an original management system that ensures safe products are provided to our customers and enables quick response to needs in the ever-diversifying social environment.

Code of Conduct

Environment , Safety & Health

We put the global environment, human safety and health as our top priorities when conducting business.


We act with integrity in compliance with laws and regulations, and show respect for human rights and local communities in which we operate.

Product Liability/Quality Assurance Management System

The Teijin Group Product Liability/Quality Assurance Regulations apply to all Teijin Group products and services and are the basis for our product liability/quality assurance activities. Based on these regulations, the Group CSR Committee and the Group Product Liability/Quality Assurance Subcommittee decide the basic policies and associated targets for all product liability/quality assurance issues of the Teijin Group, and reflect them in product liability/quality assurance activities conducted by business groups.

We have also created an original unit-based management system for product liability/quality assurance that is applied to the products of each business group. This management system aims to enhance customer satisfaction, prevent product defects, and ensure appropriate responses in the event that defects occur. The system not only covers the whole scope of the ISO standards for quality management systems but also incorporates perspectives of product liability/quality assurance, such as response to customers and product safety.

Group-wide Product Liability/Quality Assurance System

As of April 1, 2018

Implementation of Product Liability/Quality Assurance Audits

Product liability/quality assurance activities are conducted as the responsibility of each product liability/quality assurance unit. The CSR and Compliance Department, which is in charge of supervising Group-wide quality, audits these activities and checks that product liability/quality assurance mechanisms are operating appropriately.

In FY2017, we conducted regular audits of 11 business units and 5 directly managed companies with the objective of verifying operational status. Based on feedback from the audit results, we are continually enhancing the product liability/quality assurance system and process.
