CPV code 22993200 designates Heat-sensitive paper or paperboard in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
22993200 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 22993000 (Photosensitive, heat-sensitive or thermographic paper and paperboard).
