CPV code 24542000 designates Primary-form acrylic polymers in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
24542000 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 24540000 (Primary-form of vinyl polymers).
