CPV code 16110000 designates Ploughs or disc harrows in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
16110000 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 16100000 (Agricultural and forestry machinery for soil preparation or cultivation).
