CPV code 39711420 designates Hobs in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
39711420 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 39711400 (Roasters, hobs, hotplates and boiling rings).
