HS-4 · Heading
3921 — Plastic plates, sheets, film, foil and strip n.e.c. in chapter 39
Chapter 39: Plastics and articles thereof
Plain-language overview
Use HS-4 3921 when importing or exporting plastic plates, sheets, film, foil, and strips that are not classified elsewhere in Chapter 39. For example, if you're shipping cellular plastic sheets made from styrene, this heading applies directly.
To differentiate among the HS-6 lines, consider the material composition. HS-392111 covers cellular plastics made from styrene, while HS-392112 is specific to those made from vinyl chloride. If your product is made from a different polymer, you might need to look at HS-392119 for plastics not covered by the other specific codes.
If your shipment includes cellular plastics made from polyurethane, you'll want to use HS-392113. For those made from regenerated cellulose, HS-392114 is the correct choice. Products that don't fit these specific categories but are still cellular can be classified under HS-392119.
For non-cellular plastics, HS-392190 is the appropriate code. This includes any plastic plates, sheets, film, or strips that do not have a cellular structure, regardless of the polymer used.

- What types of products fall under HS-3921?
- HS-3921 includes plastic plates, sheets, films, foils, and strips that are cellular or non-cellular, made from various polymers.
- How do I determine the correct HS-6 code for my plastic product?
- Identify the polymer type and whether the product is cellular or non-cellular to select the appropriate HS-6 code from the subheadings.
- What is the difference between cellular and non-cellular plastics?
- Cellular plastics have a structure that includes air pockets, making them lighter and often used for insulation, while non-cellular plastics are solid and denser.
- Can I use HS-3921 for all types of plastic sheets?
- No, HS-3921 is specific to certain types of plastics. Ensure your product matches the descriptions in the subheadings.
- What should I do if my plastic product doesn't fit any HS-6 code under HS-3921?
- If your product doesn't fit, you may need to classify it under HS-392119, which covers plastics not elsewhere classified in heading 3921.
