Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If no rubber component present
Pure agglomerated cork sheets without rubber fall under the subheading for cork-only vulcanized sheets.
If marketed solely as rubber sheet without cork
Predominantly rubber sheets shift to Chapter 40, excluding cork composites.
If cut to specific non-sheet shapes for industrial parts
Articles of vulcanized rubber other than sheets are classified here if not fitting block/plate definitions.

Import Tips & Compliance
• Verify composition via lab testing to confirm 100% ground cork and rubber content, as binders must not alter the 'wholly of' classification
• Include detailed manufacturing specs in documentation to distinguish from cork-only agglomerates under 4504.10.20
• Avoid misdeclaration as rubber sheeting (4008) by specifying cork pulverization process
