Which code does this activity belong in?
The boundary between plastics pipe and pipe fitting manufacturing and unlaminated plastics profile shape manufacturing turns on the rigidity of the final product and its intended use. Establishments converting plastics resins into rigid pipes and fittings belong in 326122, while those producing nonrigid profile shapes such as rod, tube, and sausage casings are classified in Unlaminated Plastics Profile Shape Manufacturing. The distinction reflects differences in material properties and application rather than the conversion process itself.
