Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If flexible acrylic tubing
Flexible chemical tubes of other plastics are 3917.39, based on structural flexibility.
If part of laboratory apparatus
Lab-specific plastic fittings/articles classify under 3926.90, not generic pipes.
If articles for conveyance of gases/liquids in assembled form
Pumps/fittings for fluids may go to 3923 if functioning as complete conveyance articles.
