We have obtained GMP certifications for all of our workshops and production lines. We have also received EU GMP certification for the production of our Biqi-branded diosmectite powder in our Yaogu facility. In addition, we have passed the U.S. FDA inspection for our solid dosage form production workshop in our Nanjing facility. Our Yaogu facility and Nanjing facility have been granted ISO9001 certifications for their quality management systems.

We have established comprehensive quality control procedures and protocols that span across the entire production lifecycle. Our senior management team is actively involved in formulating internal quality control policies and monitoring our overall quality control process. Our quality control personnel are independent from our production team and are responsible for the implementation of such procedures and protocols. In addition, we utilize equipment and devices to inspect, test and ensure the quality of our raw materials, production-in-progress and final products.
