CPV code 33732000 designates Contact lenses lotions in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
33732000 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 33730000 (Eye care products and corrective lenses).
