Product Name: Oilfield Natural Polymers
Classification HS Codes and Tax Details:
1. HS Code: 3913905000
Description: Applicable to natural polymer particles, flakes, or other unlisted natural polymers.
- Base Tariff Rate: 6.5%
- Additional Tariff: 25.0%
- Special Tariff after April 11, 2025: 30.0%
- Total Tax Rate: 61.5%
Key Notes:
- This code is suitable for general natural polymer raw materials that are not specifically listed elsewhere.
- The high total tax rate (61.5%) is due to the combination of base and additional tariffs.
- Proactive Advice: Confirm the exact material composition and ensure it matches the description to avoid misclassification.
2. HS Code: 3823120000
Description: Applicable to oleic acid polymer raw materials or oleic acid polymer materials.
- Base Tariff Rate: 2.1¢/kg + 3.2%
- Additional Tariff: 7.5%
- Special Tariff after April 11, 2025: 30.0%
- Total Tax Rate: 2.1¢/kg + 3.2% + 7.5% + 30.0% = 2.1¢/kg + 40.7%
Key Notes:
- This code is specific to oleic acid-based polymer raw materials.
- The tax includes a specific duty (2.1¢/kg) and ad valorem components.
- Proactive Advice: Verify the exact chemical composition and confirm the unit price for accurate tax calculation.
3. HS Code: 3824840000
Description: Applicable to natural product mixtures.
- Base Tariff Rate: 6.5%
- Additional Tariff: 25.0%
- Special Tariff after April 11, 2025: 30.0%
- Total Tax Rate: 61.5%
Key Notes:
- This code is for mixtures of natural products, which may include oilfield natural polymers.
- The tax structure is the same as HS Code 3913905000.
- Proactive Advice: Ensure the product is not a polymer or polymer raw material, as that would fall under a different HS code.
General Alerts and Recommendations:
- April 11, 2025 Special Tariff: All three HS codes are subject to an additional 30.0% tariff after this date.
- Certifications Required: Confirm if any special permits or certifications (e.g., environmental, safety, or origin) are needed for import.
- Material Verification: Double-check the product's chemical and physical properties to ensure correct HS code classification.
- Unit Price: For HS Code 3823120000, the specific duty (2.1¢/kg) must be applied in addition to the percentage-based tariffs.
