Products classified under HTS 3915.20.00.00
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.
ABS Plastic Manufacturing Scrap
Parings and scrap from acrylonitrile-butadiene-styrene (ABS) copolymer production where styrene monomer units exceed 95% by weight of total polymer content, per subheading note (a)(1). This waste arises from injection molding of automotive parts and electronics housings.
High-Impact Polystyrene (HIPS) Trimmings
Trimmed edges and parings from HIPS sheet extrusion for refrigerator linings and packaging, consisting of polystyrene modified with polybutadiene but with ≥95% styrene units by weight. Falls under 3915.20.00.00 as styrene polymer scrap per Chapter 39 definitions.
Styrene-Acrylonitrile (SAN) Copolymer Scrap
Waste from SAN copolymer molding for kitchenware and medical devices, classified here only if styrene units comprise ≥95% of polymer weight per note (a)(2). Common scrap from blow molding operations.
Crystal Polystyrene (GPPS) Sheet Scrap
Parings from general purpose polystyrene (GPPS) sheet production for CD cases and signage, pure polystyrene with 100% styrene monomers qualifying under 3915.20.00.00 waste provisions.
Expanded Polystyrene (EPS) Packaging Waste
Post-industrial scrap from EPS foam blocks used in electronics packaging, confirmed as polystyrene polymer scrap under 3915.20.00.00 when styrene content meets Chapter 39 criteria.
Polystyrene Injection Molding Runners
Solidified sprues and runners from PS injection molding of toys and containers, pure styrene polymer waste classified in 3915.20.00.00.
Styrene Block Copolymer Reclaim Scrap
Scrap from styrene-isoprene-styrene (SIS) block copolymer film production where styrene end-blocks total ≥95% polymer weight, per note provisions.
PS Vacuum Forming Trim Waste
Skeleton trim from vacuum forming polystyrene sheets into trays and blisters, standard GPPS or HIPS material qualifying as 3915.20.00.00 scrap.
Recycled PS Bottle Flakes
Granulated flakes from post-consumer polystyrene dairy or condiment bottles, confirmed styrene polymer content for 3915.20.00.00 classification.
HIPS TV Cabinet Molding Scrap
Oversized parings from HIPS injection molds for television and monitor cabinets, styrene polymer dominant per Chapter 39 notes.
PS Foam Profile Extrusion Waste
Start-up scrap and edge trims from PS foam profile extrusion for crown molding and picture frames, qualifying as styrene scrap.
General Purpose PS Pellet Plant Purge
Purge material from GPPS pellet manufacturing lines, essentially off-spec polystyrene classified as 3915.20.00.00 waste.
Styrene Copolymer CD Jewel Case Scrap
Broken and trimmed PS/SAN cases from optical media packaging production, styrene-dominant copolymer scrap under 3915.20.00.00.
PS Thermoforming Regrind Flakes
Regrind flakes from closed-loop PS thermoforming operations for food trays, maintained styrene purity for 3915.20.00.00.
