U.S. imports of vulcanized rubber plates, sheets & strip (noncellular) (HS 400821) totaled $21.2M in April 2026, traded with 47 countries.
Importers of Vulcanized Rubber Plates, Sheets & Strip (Noncellular) paid $1.9M in duties in April 2026 — an effective duty rate of 11% on $16.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataNoncellular vulcanized rubber in flat plate, sheet, and strip form is a foundational industrial semi-finished material used across gasket manufacturing, flooring, conveyor systems, and protective lining applications. Unlike cellular (foam) rubber, noncellular grades offer solid cross-sections with predictable compression and abrasion resistance, making specification of hardness and compound critical at entry. The entire US tariff schedule for this heading consolidates into a single 10-digit line, 4008210000, simplifying classification but placing the burden of compound and grade documentation on the importer. Products subject to Section 301 measures from certain origins require careful country-of-origin determination when rubber compounding and slitting occur in multiple countries.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Noncellular rubber has a solid, non-foamed cross-section, while cellular rubber contains gas-filled voids (foam or sponge structure). CBP distinguishes them by physical examination and density testing; misclassifying a cellular product under 4008210000 can result in a reclassification to Chapter 40 headings covering cellular rubber, with different duty implications.
CBP applies a substantial transformation test: compounding raw rubber into a vulcanized compound is generally considered the origin-conferring process, not subsequent slitting or cutting to dimension. Importers should retain mill certificates, compound formulation records, and processing invoices to substantiate the claimed origin, particularly where Section 301 tariffs may apply.
