Import Tips
• Include test reports verifying vulcanization properties match synthetic rubber definition in chapter note 2
• Avoid shipping in compounded form; separate additives documentation to prevent 4005 classification
• Monitor particle size to ensure granules qualify as 'bulk forms' under primary definitions
