📌 I. Product Definition & Classification: Do You Really Understand "Plastic Sheet Stamping"?

"Plastic Sheet Stamping" refers to plastic materials processed into sheet forms, often involving punching, cutting, or forming operations. In international trade, these products are classified under Chapter 39 (Plastics and Articles Thereof), specifically focusing on plates, sheets, films, and similar flat shapes.

Key Distinction Criteria:
- Form: Flat sheets, plates, or films (not tubes, rods, or complex 3D molded parts);
- Material: Pure plastic or plastic-based composites;
- Processing: May include stamping/punching but must remain within the "sheet/plate/film" category.

⚠️ Critical Classification Point:
- If the product is a raw or semi-finished plastic sheet (even if stamped/cut), it falls under 3920 or 3921;
- If it is a finished component with specific functional use (e.g., electrical insulator, machine part), it may fall under different chapters;
- In this guide, we focus on plastic sheets in raw/semi-finished sheet form, as per the provided data.

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

🔍 Key Reminder:
- All four HS codes refer to plastic sheets that have undergone stamping/punching but remain in sheet/plate/film form;
- Do not misclassify as finished plastic parts (e.g., gears, casings) which may fall under different chapters;
- Stamping does not change the fundamental classification if the product remains a sheet/plate/film.
