Styrofoam Beads EPS
Expandable polystyrene beads used for molding into foam products like packaging and insulation. These pre-expanded or unexpanded beads contain pentane as a blowing agent and fall under HTS 3903.11.00.00 as expandable polystyrene in primary form before molding or expansion into finished articles.
EPS Raw Expanded Beads
Pre-foamed expandable polystyrene beads in granular form for rotational molding and foam block production. Classified under 3903.11.00.00 as they remain in primary expandable form with blowing agent intact, prior to final shaping.
Pentane-Infused EPS Pellets
Polystyrene pellets impregnated with pentane blowing agent for steam expansion in foam molding applications. HTS 3903.11.00.00 covers these expandable primary forms distinguished from rigid polystyrene.
White EPS Pre-Puff Beads
White-colored expandable polystyrene pre-puff beads for producing lightweight foam packaging inserts. Falls under 3903.11.00.00 as primary form polymers before final expansion and molding processes.
Unexpanded EPS Granules
Unexpanded polystyrene granules containing blowing agent for in-plant expansion into foam blocks. HTS 3903.11.00.00 precisely covers these primary form expandable polystyrene materials.
Recyclable EPS Expandable Pellets
Recycled-content expandable polystyrene pellets designed for sustainable foam production. Still classified under 3903.11.00.00 as meeting polymer content rules in primary expandable form.
