Polystyrene Foam Scrap
Waste fragments and trimmings from expanded polystyrene (EPS) foam manufacturing, primarily composed of polystyrene polymers meeting the 95% monomer content requirement per subheading note (a)(1). Classified under 3915.20.00.00 as scrap of polymers of styrene, typically generated during packaging or insulation production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing polyethylene or other polymers
Blends not meeting 95% styrene threshold classify under 'Of other plastics' per subheading note (a)(4), based on predominant monomer.
If reprocessed into usable sheets
Processed waste into plates/sheets of polystyrene moves from scrap heading 3915 to finished plates in 3921.
If misidentified as rubber waste
Synthetic rubber waste like styrene-butadiene falls under Chapter 40; styrene plastics remain in Chapter 39.

Import Tips & Compliance
• Verify polymer composition via lab testing to confirm ≥95% styrene monomer units as per Chapter 39 notes; obtain waste export permits from origin country; declare as non-hazardous to avoid EPA scrutiny
