Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If flexible PEEK tubing for same use
Flexibility criterion separates rigid from flexible other plastic pipes.
If for conveyance in machinery parts
Machinery-specific plastic tubes classify as other articles under 3926.
If imported as polymer pellets, not fabricated pipe
Unworked polymers of PEEK fall under Chapter 39 heading 3904, state of completion changes.
