HS Code for Polystyrene foam sheets
Polystyrene foam sheets are classified under HS code 392111. This classification is determined by the material composition and the physical structure of the product. Chapter 39 covers plastics, and heading 3921 is designated for other plates, sheets, film, foil, and strip of plastics. The sub-heading 392111 specifically identifies products made of "cellular" polymers of styrene. "Cellular" refers to the foam-like structure where the plastic contains numerous small cells or bubbles. These sheets are typically used for insulation, protective packaging, or signage. Because the product is cellular (foam) and has not been combined with other materials in a way that would place it in heading 3920 (which is for non-cellular plastics), it must be classified here. The classification remains 392111 regardless of whether the foam is open-cell or closed-cell, provided the base polymer is polystyrene.
Products Included
- Expanded Polystyrene (EPS) foam sheets
- Extruded Polystyrene (XPS) insulation boards
- Cellular polystyrene film for packaging
- Foamed polystyrene plates for industrial use
- Laminated polystyrene foam boards (where polystyrene predominates)
Common Misclassification
Polystyrene foam sheets are often misclassified under HS code 392030. However, 392030 is strictly for non-cellular (solid) polystyrene sheets. If the material has a foam structure, it must move to 3921. Another common error is using 392119, which is for cellular plastics made of "other" polymers (like polyurethane or PVC). Importers must verify that the polymer is indeed styrene-based to use 392111. Additionally, if the foam sheet is self-adhesive, it should be classified under heading 3919.
