CPV code 33141900 designates Blood lancets in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
33141900 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 33141000 (Disposable non-chemical medical consumables and haematological consumables).
