Import Tips

Provide oil resistance certification (ASTM standards) but classify based on cellular rubber form, not end use

Distinguish from hard rubber via durometer testing (<95 Shore A); hard rubber goes to 4008.11

Ensure no vulcanizing agents/pigments exceed chapter note 5 limits, maintaining 'simple' sheet classification
