Product Name: Low Molecular Weight Polystyrene Resin
Classification: Based on the provided HS codes and summaries, the product is likely classified under 3903905000 or 3903190000, both of which are related to polystyrene resins (a type of styrene polymer). Below is a detailed breakdown of the HS codes and associated tariff information.
✅ HS CODE: 3903905000
Description: Low molecular weight polystyrene, as a primary form of styrene polymer, is classified under 3903905000.
- Base Tariff Rate: 6.5%
- Additional Tariff (General): 25.0%
- Special Tariff (After April 11, 2025): 30.0%
- Total Tax Rate: 61.5%
- Note: This code is specific to low molecular weight polystyrene and is distinct from other polystyrene derivatives.
✅ HS CODE: 3903190000
Description: Low molecular weight polystyrene, as a primary form of styrene polymer, is also classified under 3903190000.
- Base Tariff Rate: 6.5%
- Additional Tariff (General): 25.0%
- Special Tariff (After April 11, 2025): 30.0%
- Total Tax Rate: 61.5%
- Note: This code may be used for other forms of low molecular weight polystyrene, depending on specific product attributes.
⚠️ Important Notes on Tariff Changes (April 11, 2025)
- Additional Tariffs Imposed After April 11, 2025:
- A 30.0% additional tariff will be applied to imports under these HS codes.
- This is a time-sensitive policy, and importers must be aware of the exact date to avoid unexpected costs.
📌 Proactive Advice for Importers
- Verify Material Specifications: Ensure the product is indeed low molecular weight polystyrene and not a derivative or blended material.
- Check Unit Price and Packaging: Tariff calculations may depend on the unit of measurement and packaging type.
- Certifications Required: Confirm if any technical documentation (e.g., material safety data sheets, polymerization process details) are required for customs clearance.
- Consult Local Customs Authority: For the most up-to-date and region-specific tariff information, especially regarding anti-dumping duties or special trade agreements.
