- Material Verification: Confirm the exact chemical composition and physical form of the polyisobutylene to ensure correct HS code classification.
- Certifications: Check if customs documentation (e.g., commercial invoice, certificate of origin) and certifications (e.g., REACH, RoHS) are required for import.
- Unit Price: For codes with specific duties (e.g., 5607492500), ensure the unit price is correctly declared to avoid underpayment or penalties.
📌 Proactive Advice
- Double-check the product description and technical specifications to ensure the correct HS code is used.
- Consult a customs broker or tax expert if the product is used in a specific application (e.g., food packaging, medical use) that may qualify for preferential treatment.
- Monitor policy updates after April 11, 2025, as the special tariff may change or be extended.
