Product Classification: Polystyrene Polymer Plastic Sheets
HS CODE: 3920300000, 3920995000, 3903190000, 3921110000, 3921905050
🔍 Classification Overview
Polystyrene polymer plastic sheets fall under several HS codes depending on their form, composition, and whether they are combined with other materials. Below is a breakdown of the relevant HS codes and their associated tariffs:
📌 HS Code: 3920300000
Description: Non-cellular and non-reinforced polystyrene polymer plastic sheets, films, foils, and strips.
- Base Tariff Rate: 5.8%
- Additional Tariff: 25.0%
- Special Tariff after April 11, 2025: 30.0%
- Total Tax Rate: 60.8%
Key Notes:
- This code is for pure polystyrene sheets without any reinforcement or combination with other materials.
- Ensure the product is non-cellular (i.e., not foam) and not reinforced (e.g., with fibers or fillers).
📌 HS Code: 3920995000
Description: Other non-cellular and non-reinforced plastic sheets, films, foils, and strips, layered, supported, or combined with other materials.
- Base Tariff Rate: 5.8%
- Additional Tariff: 25.0%
- Special Tariff after April 11, 2025: 30.0%
- Total Tax Rate: 60.8%
Key Notes:
- This code applies to plastic sheets that are combined with other materials (e.g., layered or laminated).
- If your product is not pure polystyrene or is combined with other materials, this may be the correct classification.
📌 HS Code: 3903190000
Description: Primary forms of styrene 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 for raw or primary forms of polystyrene (e.g., pellets or resins), not finished sheets.
- If your product is in raw polymer form, this is the correct code.
📌 HS Code: 3921110000
Description: Polystyrene foam plastic sheets.
- Base Tariff Rate: 5.3%
- Additional Tariff: 25.0%
- Special Tariff after April 11, 2025: 30.0%
- Total Tax Rate: 60.3%
Key Notes:
- This code is for foam sheets made of polystyrene.
- If your product is cellular (i.e., foam), this is the correct classification.
📌 HS Code: 3921905050
Description: Other plastic sheets, films, foils, and strips.
- Base Tariff Rate: 4.8%
- Additional Tariff: 0.0%
- Special Tariff after April 11, 2025: 30.0%
- Total Tax Rate: 34.8%
Key Notes:
- This code is for other plastic sheets that do not fall under the above categories.
- The additional tariff is 0%, which may be beneficial for certain products.
- Ensure your product does not fall under any of the more specific codes (e.g., 3920300000 or 3921110000).
⚠️ Important Alerts
- April 11, 2025 Special Tariff: All the above codes will have an additional 30% tariff applied after this date.
- Anti-dumping duties: Not applicable for polystyrene polymer sheets (unless specific to iron/aluminum, which is not the case here).
- Material Verification: Confirm the exact composition of your product (e.g., is it foam, reinforced, or combined with other materials?).
- Certifications: Check if any customs certifications or product standards are required for import (e.g., RoHS, REACH, etc.).
✅ Proactive Advice
- Verify the product form (sheet, foam, combined, etc.) and material composition to ensure correct HS code.
- Check the unit price and total value to determine if any preferential tariffs apply.
- Consult a customs broker or import compliance expert for final classification and documentation.
