Import Tips
• Document the butene-1 content (98%+) to confirm classification as polybutylene under 3902.90.00
• Ensure the product is in primary form (granules) and not mixed with other polymers
• If used in medical tubing, verify any additional regulatory requirements, though these do not affect tariff classification
