CPV code 33641300 designates Sex hormones and modulators of the genital system in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
33641300 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 33641000 (Medicinal products for the genitourinary system and sex hormones).
