Import Tips

Verify cellular structure via density testing (<0.92 g/cm³) to confirm classification as 'cellular rubber'

Provide manufacturer specs confirming vulcanized natural rubber composition; avoid misclassification as synthetic under 4008.11

Ensure sheets are simply cut to rectangular shapes without further processing to stay in heading 4008
