CPV code 03121100 designates Live plants, bulbs, roots, cuttings and slips in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
03121100 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 03121000 (Horticultural products).
