Import Tips
• 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
