CPV code 30199140 designates Paper duplicator stencils in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
30199140 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 30199100 (Carbon paper, self-copy paper, paper duplicator stencils and carbonless paper).
