The Denka Group has established quality policies in line with its management plan Mission 2030 and is conducting quality assurance activities for a wide range of products from organic chemistry using synthetic resins and resin processing, inorganic chemistry using high-performance powder control technologies, to the bio field with technologies for culturing bacteria and viruses and producing antibodies and antigens.
The Denka Group sincerely accepts the full extent of inappropriate quality conduct that has come to light, as well as the points of indication and suggestions from the external investigation committee, and has established the four "Implementation of Measures" items below to address these issues. The Denka Group will continue to put forth its utmost efforts as a group to address these issues, strengthen compliance, prevent recurrences, and restore trust.
The Company has established a Quality Assurance Department at its head office, business divisions, and factories. By promoting organic collaboration among these three layers of Quality Assurance Departments, the Company is working to improve overall quality levels across the Denka Group.
The quality risks of each product are changing due to the ongoing changes in quality requirements and laws and regulations. As part of our response to these risks, we review our quality risk assessment from market and business environment perspectives every year, and implement initiatives to reduce quality risks in a planned manner according to the nature and magnitude of the risks.
Our Group constantly monitors domestic and overseas legal revision information regarding chemical substances. For the information of chemical substances contained in products subject to legal revision, we provide revised SDSs and notify customers of the information on the contents of the products. If changes to product components or production processes are required to comply with revised laws and regulations, we will respond swiftly and appropriately.
The Denka Group has established the following Quality Assurance Policy, which is the highest internal regulation regarding quality assurance: "In regard to products, ensure compliance with laws and regulations and improve customer satisfaction." In compliance with this policy, the Denka Group conducts manufacturing and provision of reliable products under management in accordance with GMP Ordinance (Standards for Manufacturing Control and Quality Control for Pharmaceuticals)/GQP Ordinance (Standards for Quality Control for Pharmaceuticals)/GVP Ordinance (Standards for Post-Marketing Safety Management for Pharmaceuticals and Medical Devices)/QMS Ordinance (Standards for Manufacturing Control and Quality Control for Medical Devices and In Vitro Diagnostic Reagents) in the pharmaceutical business.
Furthermore, the Denka Group is a member of the Japan Vaccine Industry Association, the Japan Association of Clinical Reagents, and the Japan Medical Device Industry Association, and is working together with these organizations to contribute to the improvement of health and welfare for all people.
To provide reliable products and services, we are promoting the establishment of quality control systems.
By using systems such as the Complaint Management System, which integrates and manages customer complaint information to facilitate ongoing quality improvement, and the Chemical Substance Management System, which links information on chemical substances to product safety, we are raising our level of management and striving to further improve quality and ensure product safety.

In order to reflect customer feedback in our quality assurance activities, the Electronics and Innovative Products Division conducts a customer satisfaction survey once a year.
We analyze customer feedback from the aspects of sales, technology, quality, and delivery, and implement strategic actions for quality improvement.
Through customer satisfaction surveys, we aim to gain further trust from our stakeholders.
Our Company has established the Core Values of "Integrity" and "Innovation" as the foundation of our corporate activities. Based on these Core Values, we will continue to respond to the expectations and trust of many stakeholders, including shareholders, customers, local communities, and employees.
