π¦ HS Code Reference & Clearance Guide | 2026 Customs Tariff Analysis | Professional Import Strategy
π One, Product Definition & Classification: What is "High Gloss Polystyrene Resin"?
Polystyrene (PS) resin is one of the most widely used general-purpose thermoplastics. In international trade, "High Gloss Polystyrene Resin" typically refers to General Purpose Polystyrene (GPPS) or high-purity variants, characterized by transparency, rigidity, and a high-gloss finish. It is primarily used in packaging, disposable tableware, electronic housings, and optical components.
In the context of the provided data, these resins fall under Chapter 39 (Plastics and Articles Thereof), specifically focusing on Polystyrene (3903) and Polyethylene (3901) derivatives, depending on the specific polymer type and density.
β οΈ Key Classification Distinction:
- If the material is strictly Polystyrene (PS) β It falls under 3903.11.00.00 or 3903.19.00.00.
- If the material is High-Density Polyethylene (HDPE) (sometimes confused or blended in raw material trading) β It falls under 3901.20.10.00 or 3901.20.50.00.
- Note: The provided data groups these together with identical tax rates, but the HS codes differ based on the chemical polymer.

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
