U.S. imports of cellular plastic plates, sheets, film, foil & strip (other, nesoi) (HS 392119) totaled $115.8M in April 2026, traded with 56 countries.
Importers of Cellular Plastic Plates, Sheets, Film, Foil & Strip (Other, NESOI) paid $11.8M in duties in April 2026 — an effective duty rate of 16% on $73.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Cellular Plastic Plates, Sheets, Film, Foil & Strip (Other, NESOI) imports of $115.8M in April 2026 ran 22% above the year-to-date monthly average of $95.3M.
Last updated: April 2026 dataCellular plastic flat forms not covered by the specific polymer headings — including polyethylene, polypropylene, and other foam sheet not elsewhere classified — fall here as a residual category. A notable subdivision is 3921190010, which covers microporous sheets of polyethylene or polypropylene film used in battery separators, filtration, and breathable membrane applications. Ireland leads US supply under this heading, reflecting significant pharmaceutical and advanced-materials manufacturing investment there, with South Korea and Canada also prominent sources.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Microporous sheets have a controlled, submicron pore structure engineered for ion or fluid transport — used in lithium-ion battery separators and filtration membranes — rather than the macroscopic foam cells of conventional cellular plastics. The distinction matters for classification because 3921190010 is a dedicated line for this specific form, while other cellular polyethylene or polypropylene sheet falls under 3921190090.
Ireland hosts substantial manufacturing operations for advanced polymer films and specialty materials, including products used in pharmaceutical packaging and medical devices. This industrial base drives exports of higher-value cellular and microporous plastic sheet to the US market, distinguishing Ireland's supply profile from the commodity foam sheet sourced from other countries.
