If my business deals in both Western medicines and proprietary Chinese medicines, can they be stored in the same warehouse?

It is permissible to store Western medicines and proprietary Chinese medicines in the same warehouse, but strict physical segregation and operational separation are required to prevent cross-contamination and mix-ups. First, the warehouse must have clearly defined, physically separated areas for Western medicines and proprietary Chinese medicines. Ideally, use separate rooms or separate them with solid walls. If this is not feasible, at least store them in different areas of the warehouse using a racking system and provide very clear labels. The handling processes for the two product categories (receipt, inspection, put-away, picking and checking) should be separated as far as possible, and they should not be handled at the same workstation or at the same time. In particular, some Chinese herbal medicines may have a strong odour or generate dust, so they must be strictly segregated from Western medicines to prevent odour or physical cross-contamination.
