Product Name: Polyisobutylene Raw Material for Waterproof Materials
Classification: Based on the provided HS codes and descriptions, the most accurate classification for polyisobutylene raw material used in waterproof materials is likely HS CODE 4002310000 (Isobutylene-isoprene rubber, i.e., butyl rubber, synthetic rubber, obtained from oil).
✅ HS CODE: 4002310000
🔍 Product Description:
- This code applies to synthetic rubber derived from oil, specifically isobutylene-isoprene rubber (butyl rubber).
- Polyisobutylene is a key component of butyl rubber, and if the raw material is used in the production of butyl rubber or waterproof materials based on butyl rubber, this classification is appropriate.
📊 Tariff Breakdown:
- Base Tariff Rate: 0.0%
- Additional Tariff (General): 25.0%
- Special Tariff after April 11, 2025: 30.0%
- Total Tariff Rate: 55.0%
⚠️ Important Notes:
- April 11, 2025 Special Tariff: A 30% additional tariff will be applied after April 11, 2025. This is a time-sensitive policy and must be considered in cost planning.
- No Anti-Dumping Duties: No specific anti-dumping duties are mentioned for this product.
- No Specific Tariff for Iron or Aluminum: This product is a synthetic rubber, not related to iron or aluminum, so no additional duties apply in that context.
📌 Proactive Advice:
- Verify Material Composition: Ensure the product is indeed polyisobutylene and not a different type of synthetic rubber (e.g., chloroprene rubber or styrene-butadiene rubber), as this could affect the correct HS code.
- Check Unit Price and Certification: Confirm the unit price and whether any certifications (e.g., RoHS, REACH, or customs documentation) are required for import.
- Consult Customs Authority: If in doubt, consult with a customs broker or the local customs authority to confirm the classification and applicable duties.
🔄 Alternative HS Codes (for Reference):
| HS CODE | Description | Total Tax Rate |
|---|---|---|
| 3902205000 | Polyisobutylene (primary form) | 61.5% |
| 4002410000 | Chloroprene rubber film raw material | 55.0% |
| 4002600000 | Chloroprene rubber raw material | 55.0% |
| 4002490000 | Chloroprene rubber waterproof material | 55.0% |
Note: If the product is not butyl rubber but another type of synthetic rubber (e.g., chloroprene), the correct HS code may differ.
