Last updated: August 2026 dataPolystyrene and ABS scrap — including expanded polystyrene (EPS) foam waste — classify here and are used as secondary feedstock in plastics recycling and compounding operations. Mexico and Canada together account for the bulk of US imports, consistent with integrated North American plastics manufacturing. EPS foam scrap presents particular logistics challenges due to its low bulk density, making densification (compaction or melting) a common pre-shipment step that can affect classification if the material is processed beyond the waste/scrap threshold. Importers should document the material's origin resin type and processing state to support classification under 3915200000.

Waste and scrap classification requires that the material not have been reprocessed into a usable primary form. Mechanically compacted EPS blocks that retain their waste character (mixed colors, contamination, no defined specification) generally remain classifiable as scrap. However, if the material has been melted and extruded into ingots or pellets meeting a commercial specification, CBP may treat it as a primary-form polymer under heading 3903, not as scrap. Maintaining processing records and a clear product description helps defend the classification.
Styrene polymer scrap originating in Mexico and meeting USMCA rules of origin qualifies for preferential tariff treatment under the agreement. Importers must have a valid USMCA certification of origin and ensure the goods meet the applicable tariff shift or regional value content requirements to claim the preference at entry.
