- Anti-dumping duties: Not applicable
- Note: This code applies to modified polymer mixtures. Ensure your product is not a single polymer but a mixture.
🧪 HS CODE: 3824993910
Description: Modified mixtures used as casting adhesives
Total Tax Rate: 55.0%
- Base Tariff: 0.0%
- Additional Tariff: 25.0%
- April 11 Special Tariff (after April 11, 2025): 30.0%
- Anti-dumping duties: Not applicable
- Note: This is for modified mixtures used in casting adhesives, not directly for papermaking. Confirm if this is the correct application.
🧪 HS CODE: 3815905000
Description: Polymer modifiers
Total Tax Rate: 60.0%
- Base Tariff: 5.0%
- Additional Tariff: 25.0%

- Anti-dumping duties: Not applicable
- Note: This code applies to polymer modifiers, which may be used in papermaking. Confirm if your product is a modifier or a finished polymer.
📌 Proactive Advice:
- Verify Material Composition: Confirm whether your product is a modified natural polymer (e.g., modified starch), a synthetic polymer, or a polymer modifier.
- Check Unit Price and Certification: Some products may require technical documentation or certifications for customs clearance.
- Monitor April 11, 2025: Be aware that additional tariffs will increase by 5% after this date.
- Consult a Customs Broker: For accurate classification and compliance, especially if your product is a mixture or modifier.
