U.S. imports of non-cellular, non-reinforced polystyrene plates, sheets, film, foil & strip (HS 392030) totaled $12.9M in April 2026, traded with 28 countries.
Last updated: April 2026 dataPolystyrene sheet and film in non-cellular, unreinforced form — covering both general-purpose (GPPS) and high-impact (HIPS) grades — is consolidated into a single tariff line (3920300000) under this heading. Mexico and Canada are the primary US suppliers, with Japan and Germany also notable sources reflecting specialty optical and packaging grades. Polystyrene sheet in this form is widely used in food-service packaging, point-of-purchase displays, and thermoforming applications; importers should note that cellular (expanded) polystyrene products classify in Chapter 39 under foam headings rather than here.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
No. Heading 392030 is explicitly limited to non-cellular polystyrene sheet and film. Expanded polystyrene (EPS) foam and extruded polystyrene (XPS) board are cellular structures and classify under the cellular plastics provisions of Chapter 39 (heading 3921), not here. The non-cellular condition is a hard classification boundary.
The US schedule for 392030 has only one 10-digit line (3920300000), so GPPS and HIPS are not separated at the tariff level — both classify together. The grade distinction matters commercially for pricing and specification, but it does not create a classification difference at entry. Importers should nonetheless document the grade on commercial invoices for downstream traceability and any applicable product safety or food-contact compliance purposes.
