Quality Assurance

Quality Control

Po Sum On is dedicated to putting quality first and foremost. The company’s production units comply with the standards of the Hong Kong Department of Health’s Good Manufacturing Practice (GMP), and the company has established a comprehensive medicine manufacturing and quality management system accordingly.


In recent years, GMP has been adopted internationally by the pharmaceutical sector as a benchmark for ensuring drug quality and safeguarding public health. Specifically, GMP requires medicine manufacturers to establish standards for every production procedure. Every step of the manufacturing process is monitored for strict and full compliance, including workplace hygiene condition, workplace and equipment, manufacturing, quality control, personnel training and documentation, to ensure optimum product quality. We have stringent standard operating procedures (SOP) in place for every step of the manufacturing process, from procurement of raw materials, production to packaging of the finished product, ensuring that our products are safe and effective and of standardized quality, as well as providing a channel for tracing individual products or shipments. Once a product goes on shelf, our marketing department starts gathering market information, following up on any complaints about product quality or packaging for further investigation and rectification. As the heart of the monitoring system, our quality assurance department is manned by qualified technical staff and equipped with state-of-the-art facilities such as gas chromograph, high-performance liquid chromograph and multi-purpose microscope for faster and more accurate monitoring, as well as better control of product quality.
