Product Name: Modified Polystyrene Resin
Classification HS Code: 3911902500
🔍 HS Code Details:
- Full HS Code: 3911902500
- Product Description: Modified polystyrene resin, which is a thermoplastic material containing aromatic monomer units. It is classified under the category of petroleum resins and is suitable for various plastic and resin applications.
📊 Tariff Breakdown:
- Base Tariff Rate: 6.1%
- Additional Tariff (General): 25.0%
- Special Tariff (After April 11, 2025): 30.0%
- Total Tariff Rate: 61.1%
⚠️ Note: The additional tariff of 30.0% applies specifically after April 11, 2025. This is a time-sensitive policy and must be considered when planning import timelines.
📌 Key Considerations:
- Material Verification: Confirm that the product is indeed modified polystyrene resin and not another type of modified resin (e.g., polypropylene, polyethylene, or polyester), as this could affect the correct HS code.
- Unit Price and Certification: Ensure that the unit price and documentation (e.g., material safety data sheets, technical specifications) are accurate and complete for customs clearance.
- Certifications Required: Depending on the destination country, certain certifications (e.g., REACH, RoHS, or environmental compliance) may be required. Verify these in advance.
- Anti-Dumping Duties: While not explicitly mentioned for this product, be aware that anti-dumping duties may apply to certain polymers, especially if imported from countries under such measures.
🛠️ Proactive Advice:
- Double-check the product composition to ensure it falls under HS Code 3911902500 and not a different category (e.g., 3903190000 for primary forms of styrene polymers).
- Consult with a customs broker or expert if the product contains additives or is used in a specific application (e.g., in electronics or construction), as this may influence classification.
- Plan for the April 11, 2025, tariff increase to avoid unexpected costs during importation.
