HS Code for Cellular plastic sheets

Cellular plastic sheets that do not fall under the specific subheadings for styrene, vinyl chloride, or polyurethanes are classified under HS code 3921.19. This is a residual or "other" category within the cellular plastics group. The classification is determined by the material's cellular (foamed or expanded) structure and the fact that the base polymer is not one of the more common types explicitly listed in codes 3921.11 through 3921.14. Common materials found in this category include cellular polyethylene (PE), cellular polypropylene (PP), and cellular polyethylene terephthalate (PET). These products are characterized by their lightweight, insulating, and cushioning properties. To be classified here, the sheets must not be reinforced, laminated, or combined with other materials in a way that would move them to the "non-cellular" or "other" categories of 3921.90.

Products Included

• Cellular polyethylene (PE) foam sheets
• Cellular polypropylene (PP) sheets
• Expanded PET foam panels
• Cellular silicone sheets
• Other foamed plastic sheets not elsewhere specified

Common Misclassification

This code is frequently confused with 3921.13 (cellular polyurethanes) or 3921.11 (cellular polystyrene) because the physical appearance of different plastic foams can be nearly identical. Accurate chemical identification of the polymer is required. It is also often misclassified under 3920 if the "cellular" nature is not recognized, or under 3921.90 if the sheet is mistakenly thought to be reinforced with textile or metal.

FAQ

What is the HS code for Cellular plastic sheets?

If the plastic is not styrene, PVC, or polyurethane, the HS code for cellular plastic sheets is 3921.19.

Does this code include bubble wrap?

No, bubble wrap is typically classified under 3920.10 (if polyethylene) because the "cells" are trapped air between layers of non-cellular film, rather than a foamed material mass.
