If my pharmaceutical wholesale business is very small and I have only rented a small warehouse, do I still need to meet all GDP requirements?

Yes, this is absolutely required. A fundamental principle of Hong Kong's pharmaceutical regulation is that all licence holders are treated equally. Regardless of the size of your business, if you engage in the wholesale, storage or distribution of medicines, you must fully comply with all applicable requirements of the Pharmacy and Poisons Ordinance and Good Distribution Practice (GDP). The regulatory authority's primary concern is the quality and safety of medicines, which is unrelated to company size. A poorly managed small warehouse may also lead to medicines deteriorating, being stolen or being dispatched in error, posing a threat to public health. Therefore, even if you have only a small warehouse and a few staff, you still need to establish a complete Quality Management System (QMS), including a compliant premises layout (functional zoning), temperature and humidity controls and records, security measures, written SOPs, complete record-keeping and staff training.
