CPV code 03117120 designates Plants used in pharmacy in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
03117120 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 03117100 (Plants used in perfumery or pharmacy, or for insecticidal or similar purposes).
