β»οΈ Styrene Copolymer Waste (Polystyrene Scrap/Debris)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy for PS Waste Imports
π I. Product Definition & Classification: What is "Styrene Copolymer Waste"?
"Styrene Copolymer Waste" primarily refers to Polystyrene (PS) in the form of waste, scraps, chips, orθΎΉθ§ζ (offcuts). It is not raw material for manufacturing new finished goods in the traditional sense, but rather recyclable plastic residue. In international trade, the classification hinges on whether it is classified as raw polymer (rare for waste) or plastic waste/scrap.
β οΈ Key Distinction:
- If it is raw, unmolded PS pellets intended for reuse without being considered "waste" βε½ε ₯ 3903.xx (Primary Forms)
- If it is discarded, used, or scrap PS (chips, flakes, bulk waste) βε½ε ₯ 3915.xx (Plastic Waste & Scrap)
- Crucial Note: The term "Copolymer" in the user input likely refers to general Polystyrene categories. Customs often groups general PS waste under specific PS waste codes rather than generic "other plastics" if the material identity is clear.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Match)
Based on the provided data, the following HS Codes are matched based on Material (Polystyrene/Styrene Polymer) and Form (Waste/Scrap/Raw Residue).
| HS Code | Product Description | Matching Logic | Tax Profile |
|---|---|---|---|
3903.11.00.00 |
Polystyrene, in primary forms | Material Match: Polystyrene. Form Match: Classified as "Primary Form/Raw Material" despite the name "Waste". Assumes high-purity recyclable input. | Total: 41.5% |
3915.90.00.90 |
Waste, fragments, and scraps of plastics (other) | Material Match: Polystyrene (Plastic). Form Match: Waste/Scrap. Classified under "Other Plastics" if not specifically listed as PS scrap elsewhere. | Total: 35.0% |
3903.19.00.00 |
Other Polystyrene, in primary forms | Material Match: Polystyrene. Form Match: Waste inferred as "Bulk/Raw State". Similar to 3903.11 but for non-expanded or specific PS types. | Total: 41.5% |
3915.20.00.00 |
Waste, fragments, and scraps of polystyrene | β Perfect Match: "Styrene Copolymer" = Polystyrene; "Waste" = Waste/Scrap. This is the most precise code for PS scrap. | Total: 35.0% |
3915.10.00.00 |
Waste, fragments, and scraps of polymers of ethylene | β οΈ Mismatch Risk: Matches "Ethylene Polymer" not "Styrene". Included in data as a potential error or broad misclassification. | Total: 35.0% |
π Critical Analysis:
-3915.20.00.00is the most accurate classification for "Styrene Copolymer Waste" (Polystyrene Scrap).
-3915.90.00.90is a fallback if the material is mixed or less clearly identified as pure PS.
-3903.11.00.00/3903.19.00.00are high-risk classifications for "Waste". Using these implies the material is "Primary Form" (raw pellets), which may trigger audits if the product is visibly scrap. However, if the waste is processed into clean, uniform chips suitable for immediate re-extrusion, some customs authorities may accept this, leading to higher tax (41.5%).
-3915.10.00.00is likely incorrect for Styrene products (it is for Polyethylene).

π οΈ IV. Customs Clearance Practical Advice (Avoid Pitfalls)
β 1. Documentation Checklist (Mandatory)
| Document | Required | Description |
|---|---|---|
| β Material Safety Data Sheet (MSDS) | βοΈ | Confirm no hazardous substances mixed with PS waste. |
| β Commercial Invoice | βοΈ | Must clearly state "Styrene Copolymer Waste" or "Polystyrene Scrap". Avoid vague terms like "Plastic Pieces". |
| β Packing List | βοΈ | Detail weight, volume, and packaging type (bales, bags, bulk). |
| β Certificate of Origin | βοΈ | Essential for confirming China origin and applying surtaxes. |
| β Photos of Goods | βοΈ | Show the waste form (flakes, chips, bales) to support HS Code 3915 classification. |
| β Third-Party Inspection Report | βοΈ | Verify purity and material type (PS vs. Mixed Plastics). |
β 2. Declaration Strategy (Key Tips)
π₯ "Be Honest on Form, Be Precise on Code!"
| Scenario | Correct Declaration | Incorrect Practice | Consequence |
|---|---|---|---|
| Clean PS Flakes | 3915.20.00.00 (Polystyrene Waste) |
Declaring as 3903.11 (Raw PS) without proof |
High audit risk, potential penalty |
| Mixed Plastic Scrap | 3915.90.00.90 (Other Plastic Waste) |
Declaring as pure PS waste | Misclassification, delay |
| PS Bottles (Unprocessed) | 3915.20.00.00 |
Declaring as finished goods | Wrong HS Code, 35-41.5% tax |
| Contaminated Waste | 3915.20.00.00 + EPA Permit |
No EPA Permit | Rejection/Return |
β 3. Special Considerations
| Issue | Advice |
|---|---|
| EPA Regulations | Plastic waste imports may require EPA notification (TSCA). Ensure compliance with US EPA rules on imported plastic waste. |
| Contamination | If waste contains >5% non-PS material, declare as 3915.90.00.90 to avoid misclassification penalties. |
| Pre-cleaning | Clean, dry, and compacted waste is easier to classify as 3915.20.00.00. Dirty, mixed waste may be rejected or classified differently. |
| Value Declaration | Ensure CIF value includes freight and insurance. Under-declaring value triggers audits. |
π V. Global Market Comparison (2026 Update)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Notes |

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
