CPV code 15543200 designates Cheddar cheese in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
15543200 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 15543000 (Grated, powdered, blue-veined and other cheese).
