DDC is certified under the ISO 9001, ISO 14001, and ISO 45001 standards.

Chengdu Dadi Hank Biotechnology Co., Ltd. is one of the pioneering companies in the industry to have achieved ISO 9001 certification, having first obtained this accreditation as early as 2002. As the company expanded into overseas markets, it further pursued FAMI-QS certification (the European Quality System for Feed Additives and Premixes) in 2018. In 2023, the company took its quality management system development to a new level, successfully passing a five-day on-site audit by an expert team from the China Quality Certification Center in March. As a result, it smoothly earned ISO 9001, ISO 45001, and ISO 14001 certifications, with the official certificates being officially issued in April.

ISO 9001 is the quality management system standard developed by the International Organization for Standardization (ISO), while ISO 14001 is the environmental management system standard, and ISO 45001 focuses on occupational health and safety management systems. Product quality is regarded as the company’s lifeline. By rigorously implementing both the ISO 9001 and FAMI-QS management systems, the company adopts a comprehensive product-centric approach—from product research and development to design, raw materials, production facilities, and inspection and testing—striving to push product quality to its absolute limit. Green and sustainable development is the company’s long-term value-driven strategy. Safety, environmental protection, and occupational health are firmly established as the cornerstones of the company’s growth, seamlessly integrated into its overall business management framework. In terms of infrastructure construction and technological upgrades, the company strictly adheres to the "three simultaneous" principle: ensuring environmental protection, production safety, and occupational hazard control measures are implemented concurrently at every stage—ranging from preliminary assessments and facility design to effectiveness evaluations and final acceptance. This systematic, end-to-end approach has yielded remarkable results. For instance, the company has continuously invested over 12 million yuan in upgrading and improving its proprietary bio-environmental protection system, which now boasts independent intellectual property rights and has earned high recognition within the industry. Moreover, the company has been consistently rated by Chengdu’s Bureau of Ecology and Environment as an “Environmentally Trusted Enterprise”—the highest-level designation for environmental credibility—for multiple years running. Through ongoing technological innovation and proactive implementation of intrinsic safety measures, the company has significantly enhanced workplace environments and working conditions, achieving full compliance with safety standards and effectively eliminating occupational health risks. These efforts have not only ensured stable business operations but also made substantial contributions to environmental protection, employee well-being, and societal stability.

Through this three-system certification, the company will further enhance its standardized practices in quality, safety, environmental protection, and occupational hazard management. It will establish a proactive mechanism for self-improvement and continuous enhancement, leveraging the system’s unique features such as daily monitoring and measurement, annual audits, and management reviews. This approach will enable the company to promptly identify potential management issues, fulfill its social responsibilities as a corporate citizen, and achieve ongoing improvements in its overall management effectiveness.
