CPV code 39712300 designates Hand-drying apparatus in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
39712300 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 39712000 (Electrical domestic appliances for use with the human body).
