Must the winning bidder be a manufacturer in the procurement of consumables with quantity?

No, the winning enterprise must be a public medical institution, according to the inquiry of a good doctor. Centralized procurement of pharmaceutical consumables can be understood as "group purchase" of pharmaceutical consumables, that is, countries, provinces and cities package drugs purchased by hospitals in a decentralized way and place orders directly with production enterprises in the form of group purchase, thus reducing circulation links, ensuring product quality, lowering the prices of drugs and consumables and reducing the burden on patients.
