Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-cellular (solid) rubber
Loses cellular classification; moves to plates/sheets/strip/rods of non-cellular natural rubber.
If primarily plastic composition
Chapter 40 excludes goods of Section XI (textiles); plastic-rubber blends classified by predominant material.
If imported as finished vehicle part
Completed automotive seals classified as articles of vulcanized rubber rather than raw profile shapes.

Import Tips & Compliance
• Verify cellular structure via density testing (<0.92 g/cm³) to confirm classification from non-cellular 4008.11
• Provide manufacturer specs confirming natural rubber composition >50% to avoid synthetic rubber headings
• Include extrusion process documentation to distinguish profiles from simple strips
