CPV code 42810000 designates Parts of machinery for paper or paperboard production in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42810000 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 42800000 (Machinery for paper or paperboard production).
