CPV code 16820000 designates Parts of forestry machinery in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
16820000 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 16800000 (Parts of agricultural and forestry machinery).
