Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as unfinished polymer sheet rather than machined cylinder
Plain polymer plates or sheets without machine-part features go to Chapter 39 plastics.
If parts of machinery for working plastics in primary forms
Primary polymer processing equipment parts classify under 8477, not general rolling machines.
