What this code covers

Use this class for manufacture of tubes, pipes, hollow profiles and related fittings, of steel when the main activity includes Manufacture of seamless tubes and pipes of circular or non-circular cross section and of blanks of circular cross section, for further processing, by hot rolling, hot extrusion or by other hot processes of an intermediate product, which can be a bar or a billet obtained by hot rolling or continuous casting and Manufacture of precision and non-precision seamless tubes and pipes from hot-rolled or hot-extruded blanks by further processing, by cold drawing or cold rolling of tubes and pipes of circular cross section and by cold drawing only for tubes and pipes of non-circular cross section and hollow profiles. Check exclusions and nearby codes before applying it to a mixed activity.
