The Denka Group handles a broad range of operations with an extensive product lineup ranging from various organic and inorganic materials to electronic materials and pharmaceuticals. Reflecting a quality policy that aligns with the Denka Group ESG Basic Policy, we are engaging in quality assurance activities encompassing this diversity, striving to satisfy quality requirements in the business fields relevant to our products and services and to meet customer needs in light of the latest social expectations.
The Denka Group maintains a hygiene control system for food additives, food packaging materials and other food-related products that conforms with the mandatory Hazard Analysis and Critical Control Point (HACCP)*food hygiene control method stipulated by the 2018 partial revision of the Food Sanitation Act.
The Denka Group constantly monitors and collects information regarding the status of legal revisions at home and abroad to ensure it is positioned to swiftly respond appropriately to the latest laws and regulations governing chemical substances. Whenever a new chemical substance-related regulation comes into effect, we ensure that all relevant business units are informed and weigh our options regarding the adoption of safer alternatives or otherwise implementing the measures necessary to maintain regulatory compliance.
To enhance customer satisfaction, we are developing an IT-based infrastructure that supports our quality management. Encompassing an upgrade of the existing customer complaint management system, the infrastructure is expected to enhance our ability to address customer grievances and complaints. Moreover, it will help increase the sophistication of design reviews undertaken at the research, design and development stages to ensure that customer needs are promptly and accurately met while updating our system for managing the functional and quality specification documents furnished to customers at the time of delivery. In these ways, we strive to enhance the reliability and efficiency of our operations and facilitate the effective utilization of accumulated data.
The Denka Group handles diverse products from commodities to specialty products and is positioned to handle a similar level of diversity in the risk arising from each product. Moreover, the risk arising from each product is changing by social needs, such as the growing public call for businesses to contribute to the United Nations Sustainable Development Goals even as they strive to meet customer requirements for even higher product quality. With this in mind, we annually review results of the quality risk assessments for all products from the perspective of both the market environment and business environment. We also perform systematic initiatives to mitigate various quality risks based on assessments of their characteristics and magnitude.
In November 2021, we confirmed that the some products in our QuickNaviTM-COVID-19 Ag rapid antigen diagnostic test kits for novel coronavirus antigens may have an increased false positive rate. Denka made the decision to recall all applicable products (Class II*) in consideration of the safety of consumers. The collection and replacement work was completed by the end of March 2022, and we have received no reports of adverse health effects. We will continue to strengthen our quality assurance framework and strive to provide more reliable products and services.
