Import Tips
• Confirm the product is in primary form (pellets) and that butene-1 content is above 95% to meet the polybutylene designation
• Check if the pellets are subject to any Canadian standards for plumbing applications, though this does not affect tariff classification
• Retain shipping documents showing the product is not a finished article, as that would change classification
