CPV code 42716200 designates Drying machines in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42716200 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 42716000 (Laundry washing, dry-cleaning and drying machines).
