Product Name: High Refractive Index Polystyrene Resin
Classification Analysis:
Based on the product description, two potential HS codes may apply. Here's a detailed breakdown:
✅ Option 1: HS Code 3903190000
Product Description: High transparency polystyrene, high molecular weight polystyrene, etc.
Classification: Polystyrene (styrene polymer) in its primary form, other types of polystyrene.
- Base Tariff Rate: 6.5%
- Additional Tariff (General): 25.0%
- Special Tariff (After April 2, 2025): 30.0%
- Total Tax Rate: 61.5%
✅ Option 2: HS Code 3906100000
Product Description: Acrylic resin (high refractive index) falls under the category of acrylic resins.
Classification: Polymers of acrylic acid or methacrylic acid, other forms.
- Base Tariff Rate: 6.3%
- Additional Tariff (General): 25.0%
- Special Tariff (After April 2, 2025): 30.0%
- Total Tax Rate: 61.3%
📌 Key Notes and Recommendations:
-
Tariff Changes After April 2, 2025:
Both HS codes will be subject to an additional 30.0% tariff after this date. Ensure your customs clearance timeline accounts for this change. -
Material Verification:
Confirm the exact chemical composition and whether the product is polystyrene or acrylic-based. This will determine the correct HS code. -
Certifications Required:
Check if any certifications (e.g., REACH, RoHS, or specific import permits) are required for the resin type and its intended use. -
Unit Price and Classification:
The final HS code may also depend on the unit price and whether the product is considered a "primary form" or a "processed product."
🛑 Proactive Advice:
- Consult a customs broker or classification expert if the product contains additives or is used in a specific application (e.g., optical components).
- Keep documentation on the resin’s chemical structure and manufacturing process to support classification.
