📌 I. Product Definition & Classification: What Exactly is "PS Plastic Shell"?

"PS Plastic Shell" (Polystyrene) is a versatile material used in packaging, protective casings, and consumer goods. In international trade, the classification of Polystyrene (PS) products depends heavily on form, function, and state of processing.

It is generally categorized into two main types:

• Plastic Packaging Articles: Such as films, bags, boxes, and protective shells specifically designed for packaging goods. These fall under Chapter 39, Headings 3923 or 3926.
• Plastic Plates, Sheets, Film, Foil, and Tape: Raw or semi-finished materials, such as rolls of plastic film or sheets, which are not yet fabricated into specific containers or casings. These fall under Chapter 39, Headings 3919 or 3920.

⚠️ Key Distinction Point:
- If the PS item is a finished packaging component (e.g., a clamshell container, a protective bubble wrap layer, a box lid) intended to hold or protect other goods → Classify under 3923 or 3926 (Packaging Articles).
- If the PS item is a material form (e.g., a roll of plastic film, a sheet of transparent film) → Classify under 3919 or 3920 (Plastic Films/Sheets).

📊 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)

Based on the provided data for "PS Plastic Packaging Film/Membrane", here are the applicable HS Codes and their logic:

🔍 Important Note:
- 3923.29/3923.90 (38.0%): Applies to finished or semi-finished packaging goods. If your "PS Plastic Shell" is a clear clamshell box or a protective film roll sold for packaging purposes, this is likely the correct category.
- 3919/3920 (40.8%): Applies to raw plastic films/sheets. If the product is a roll of PS film intended for further manufacturing, or if customs authorities view the "shell" as a sheet material rather than a packaging article, this higher rate may apply.
