Here is the structured and professional breakdown of the HS codes and associated tariffs for the Natural Polymer Mold Additives product classification:
📦 Product Classification Overview
All products fall under HS Code 3913.90.50.00 and 3824.99.11.00, 3824.99.41.90, depending on the specific material and form.
📊 HS Code: 3913.90.50.00
Product Types:
- Natural polymer sheet raw material
- Natural polymer granules
- Modified natural polymer powder
Tariff Breakdown:
- Base Tariff Rate: 6.5%
- Additional Tariff (General): 25.0%
- Special Tariff (After April 11, 2025): 30.0%
- Total Tax Rate: 61.5%
Key Notes: - This code applies to various forms of natural polymer materials used in mold additives. - The April 11, 2025 special tariff significantly increases the total tax burden. - Ensure the product is correctly classified based on its material type and physical form (sheet, granule, powder).
📊 HS Code: 3824.99.11.00
Product Type: - Mold-use chemical adhesive
Tariff Breakdown:
- Base Tariff Rate: 0.0%
- Additional Tariff (General): 25.0%
- Special Tariff (After April 11, 2025): 30.0%
- Total Tax Rate: 55.0%
Key Notes: - This code applies to chemical adhesives used in mold applications. - No base tariff, but the additional and special tariffs still apply. - Confirm the chemical composition and intended use to ensure correct classification.
📊 HS Code: 3824.99.41.90
Product Type: - Plant-based fat casting mold adhesive
Tariff Breakdown:
- Base Tariff Rate: 4.6%
- Additional Tariff (General): 25.0%
- Special Tariff (After April 11, 2025): 30.0%
- Total Tax Rate: 59.6%
Key Notes: - This code applies to plant-based fat adhesives used in casting molds. - The base tariff is slightly higher than the chemical adhesive (3824.99.11.00). - Ensure the raw material source (plant-based fat) is clearly documented.
⚠️ Important Alerts and Recommendations
- April 11, 2025 Special Tariff: All products listed are subject to an additional 30.0% tariff after this date. This is a time-sensitive policy and may significantly increase import costs.
- Anti-dumping duties: Not currently applicable for these products, but always verify with the latest customs updates.
- Certifications: Confirm if any product certifications (e.g., REACH, RoHS, or specific import permits) are required for the destination country.
- Material Verification: Ensure the material composition and physical form match the HS code description to avoid misclassification and penalties.
✅ Proactive Advice for Importers
- Double-check the product form (sheet, granule, powder, adhesive) and material source (natural polymer, plant-based fat, chemical adhesive).
- Review the April 11, 2025 tariff change and plan accordingly for cost estimation.
- Consult customs or a compliance expert if the product is a blend or modified form of multiple materials.
- Keep documentation (e.g., material safety data sheets, product specifications) ready for customs inspection.
