Classification: Based on the provided HS codes, the most relevant classification for polybutylene flakes is likely HS CODE: 3902900010 ("聚丁烯树脂颗粒" – Polybutylene Resin Particles). However, it's important to confirm the exact chemical composition and form of the product for accurate classification.
🔍 HS CODE: 3902900010 – Polybutylene Resin Particles
Total Tax Rate: 61.5%
Tax Breakdown:
- Base Tariff Rate: 6.5%
- Additional Tariff: 25.0%

Material Verification:
Confirm that the product is indeed polybutylene and not another similar polymer (e.g., polypropylene or polyethylene), as misclassification can lead to incorrect tariff application. -
Unit Price and Certification:
Verify the unit price and check if any certifications (e.g., REACH, RoHS, or customs documentation) are required for import compliance. -
Alternative HS Codes:
If the product is not resin particles but flakes, ensure that the form (flakes vs. particles) is correctly classified. If in doubt, consult a customs broker or classification expert.
📌 Proactive Advice:
- Double-check the product description with the customs authority or a classification expert to ensure the correct HS code is used.
- Keep records of material specifications, supplier documentation, and product samples for audit purposes.
