Import Tips
• 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
