CPV code 42991400 designates Dryers for wood, paper pulp, paper or paperboard in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42991400 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 42991000 (Paper, printing and bookbinding machinery and parts).
