HS Code for Expandable polystyrene

Expandable Polystyrene (EPS) is classified under HS code 3903.11. This classification falls under Chapter 39 (Plastics and articles thereof) and heading 3903, which covers polymers of styrene in primary forms. The subheading 3903.11 is specifically designated for "expansible" polystyrene. These are typically small beads or granules containing a blowing agent (such as pentane) that allows the material to expand when heated with steam. The classification is determined by the chemical composition (styrene polymer) and the physical state (primary form/granules) as well as the specific property of being expansible for foam production.

Products Included

• EPS beads
• Expandable polystyrene granules
• Raw polystyrene for foam block molding
• Unexpanded polystyrene pellets with blowing agents
• EPS resin for packaging manufacture

Common Misclassification

Expandable polystyrene is often confused with HS code 3903.19, which covers "other" polystyrene in primary forms that are not expansible (such as General Purpose Polystyrene or GPPS). Another common misclassification is HS code 3921.11, which covers plates, sheets, film, foil, and strip of cellular polystyrene. The distinction is that 3903.11 is for the raw material in primary form, while 3921.11 is for the finished, expanded foam products like insulation boards or packaging blocks.

FAQ

What is the HS code for Expandable polystyrene?
