HS Code for EPS beads
Expansible Polystyrene (EPS) beads are classified under HS code 3903.11 because they represent a specific primary form of styrene polymer. The "expansible" designation is the critical factor for this classification; these beads contain a blowing agent, typically a volatile hydrocarbon like pentane, which allows the material to expand significantly when exposed to heat, usually in the form of steam. This physical property distinguishes them from standard polystyrene resins. Under Chapter 39 of the Harmonized System, which governs plastics and articles thereof, polymers of styrene are grouped under heading 3903. Subheading 3903.11 is reserved exclusively for the expansible variety in primary forms such as granules, pellets, or beads. The classification is based on the chemical composition—where styrene units must predominate by weight—and the specific functional characteristic of being heat-expandable for the production of cellular plastics used in insulation and packaging.

Common Misclassification
EPS beads are often confused with HS code 3903.19, which covers "other" polystyrene in primary forms, such as General Purpose Polystyrene (GPPS) or High Impact Polystyrene (HIPS) that are not expansible. Another major misclassification occurs with 3921.11, which covers finished plates, sheets, or blocks of cellular polystyrene. Importers must distinguish between the raw, unexpanded beads (3903.11) and the finished foam products (3921.11).
FAQ
What is the HS code for EPS beads?
The HS code for EPS beads is 3903.11, specifically for expansible polystyrene in its primary form.
Does this code include recycled polystyrene?
If the recycled material is processed back into expansible primary beads, it remains under 3903.11; however, general plastic waste or scrap is classified under 3915.20.
