Import Tips
• Verify the rubber is noncellular (no foam structure) via density testing to confirm classification under 4008.21
• Provide mill test certificates showing vulcanization and composition to avoid misclassification as unvulcanized rubber (4002)
• Ensure sheets are rectangular and not custom-cut to article shapes, which would shift to heading 4016
