⚠️ Important Notes and Recommendations
-
Primary Recommendation:
Based on the description, HS Code 3902900010 is the most appropriate classification for PolyPentene Resin Flakes, assuming it is a polymer of butene in primary form. -
Tariff Alert:
Additional tariffs of 30.0% will apply after April 11, 2025. Ensure your customs declaration includes the correct HS code and documentation to avoid penalties. -
Proactive Actions Required:
- Verify the chemical composition of the resin to confirm it is indeed polybutene.
- Check the unit price and certifications required (e.g., Material Safety Data Sheet, REACH compliance, etc.).
-
Confirm the form (primary or secondary) of the resin, as this affects classification.
-
Customs Clearance Tip:
If the product is not in primary form (e.g., processed into sheets or other forms), the classification may change. Always confirm with a customs broker or classification expert if in doubt.
