Product Name: Alginate Based Gel Material
Classification HS Code Analysis:
Below is the detailed breakdown of the HS codes and associated tariff rates for alginate-based gel materials, based on the provided data:
🔍 HS Code: 3913902090
Description: Alginate gel, a natural polymer and its derivatives
Total Tax Rate: 60.8%
- Base Tariff Rate: 5.8%
- Additional Tariff: 25.0%
- Special Tariff after April 11, 2025: 30.0%
- Note: This code applies to finished alginate gels, which are more processed than raw materials.
🔍 HS Code: 3913100000
Description: Alginate salt chemical raw material, a primary form of natural polymer
Total Tax Rate: 41.7%
- Base Tariff Rate: 4.2%
- Additional Tariff: 7.5%
- Special Tariff after April 11, 2025: 30.0%
- Note: This code applies to raw alginate salts (e.g., sodium alginate, calcium alginate), which are unprocessed or minimally processed.
🔍 HS Code: 3913905000
Description: Calcium alginate gel, a primary form of natural polymer material
Total Tax Rate: 61.5%
- Base Tariff Rate: 6.5%
- Additional Tariff: 25.0%
- Special Tariff after April 11, 2025: 30.0%
- Note: This code is for calcium alginate gels, which are semi-finished or processed forms of alginate.
📌 Key Observations:
-
Tariff Increase Alert:
A 30.0% additional tariff will be imposed after April 11, 2025, for all the above HS codes. This is a time-sensitive policy and must be considered in cost planning. -
Material Classification Matters:
The HS code depends heavily on the form and processing level of the alginate material. For example: - Raw alginate salts fall under 3913100000.
-
Processed gels (e.g., calcium alginate gel) fall under 3913905000 or 3913902090.
-
Anti-Dumping Duties:
No specific anti-dumping duties are mentioned for this product category in the provided data. However, it is recommended to verify if any anti-dumping or countervailing duties apply, especially for imports from certain countries.
✅ Proactive Advice:
-
Verify Material Specifications:
Confirm the exact chemical form (e.g., sodium, calcium, or other salts) and processing level (raw, semi-finished, or finished) of the alginate material to ensure correct HS code classification. -
Check Required Certifications:
Some countries may require product certifications (e.g., food-grade, medical-grade, or industrial use) for customs clearance. Ensure all necessary documentation is in place. -
Monitor Tariff Changes:
Keep track of April 11, 2025, as the 30.0% additional tariff will significantly impact import costs. Consider adjusting pricing or sourcing strategies accordingly. -
Consult Customs Broker:
For complex or high-value shipments, it is advisable to seek assistance from a customs broker or compliance expert to avoid misclassification and penalties.
