CPV code 39722300 designates Parts of plate warmers in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
39722300 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 39722000 (Parts of stoves, cookers, plate warmers and domestic appliances).
