Import Tips
• Include chemical resistance certifications (e.g
• ASTM standards) to support rubber classification and duty rate application
• Avoid bulk packaging that suggests 'parts of machines' to prevent reclassification under heading 8484
• Declare exact durometer hardness to confirm not hard rubber, which would exclude from this HTS
