CPV code 16630000 designates Machinery for preparing animal feeding stuffs in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
16630000 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 16600000 (Specialist agricultural or forestry machinery).
