Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-cellular filter sheets
Solid (non-foamed) structure classifies under other non-cellular plastics.
If assembled into complete filter cartridges
Finished filtering machinery parts move to Chapter 84.
If with attached plastic fittings
Tubes/pipes/hoses with fittings get free (C) rate under 3917 US note.

Import Tips & Compliance
• Provide filtration performance specs and polymer certificates for industrial use validation
• Ensure no plasticizer additives per subheading note to prevent shift to 3920.43
• Import in large rolls to qualify as sheets, avoiding parts classification in 3926
