CPV code 33914100 designates Post-mortem thread in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
33914100 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 33914000 (Post-mortem thread, needles or incision clips).
