Expandable Polystyrene EPS Beads F400
EPS F400 consists of polystyrene beads impregnated with pentane blowing agent, with styrene monomer >95% by weight in primary bead form. It is classified under HTS 3903.90.5000 as 'Other' polymers of styrene in primary forms. Subheading note (a)(1) applies as it is not chemically modified or a named copolymer.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If styrene-butadiene copolymer beads
Named styrene-butadiene copolymers with >95% comonomers go to 3901.30 per note (a)(2).
If imported pre-expanded as cellular plastic articles
Expanded EPS foam is a finished cellular article under 3921, not primary form polymer.
If chemically modified with significant non-styrene modifications
Modifications not covered elsewhere place it in 'Other' of 3902 series per note (a)(3), if predominant monomer shifts.

Import Tips & Compliance
• Include blowing agent specs in documentation to confirm primary form status under Chapter 39
• Verify no 'household article' features to avoid 3924; EPS beads are industrial raw material
