Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cut to non-rectangular profiles or surface-worked beyond simple cuts
Profile shapes or further worked strips in heading 4008 exclude simple rectangular strips of 4005.
If in latex or dispersion form for synthetic rubber
Unvulcanized synthetic rubber latex falls under heading 4002 primary forms, not solid strips.
If textile-impregnated for conveyor belting during import
Belting of textile fabric coated with rubber is specifically in heading 4010, regardless of vulcanization.

Import Tips & Compliance
• Confirm strip width and form meet 'simply cut to rectangular shape' criteria to avoid heading 4008 profile shapes
• Include certificates of analysis showing no vulcanizing agents for CBP verification
• Package in bulk rolls without retail packaging to maintain primary form status
