DDC is one of the first enterprises in the industry to pass ISO9001 certification. As early as 2002, it passed the system certification. With the development of the company's overseas market, in 2018, the company also passed the FAMI-QS (European Feed Additives and Premixed Feed Quality System) certification. In 2023, the company's system construction work took it to a new level. After a five day on-site audit by the expert group of the China Quality Certification Center in March, it successfully passed the ISO 9001, ISO 45001, and ISO 14001 three system certifications. The system certification certificate was officially issued in April.
