Last updated: April 2026 dataFlat-form unvulcanized rubber compounds not compounded with carbon black or silica—and not in solution or dispersion—are captured under 4005910000 as plates, sheets, and strip. These semi-finished forms are used by downstream fabricators for gaskets, seals, and molded parts, where the sheet format allows precise die-cutting before vulcanization. Mexico and Canada together dominate US imports, consistent with integrated North American automotive and industrial supply chains; Germany and France supply specialty-grade material for higher-performance applications.

The critical distinction is vulcanization state: 400591 covers sheets that have not yet been cured (cross-linked), while heading 4008 covers sheets of vulcanized rubber. Importers should obtain a statement from the manufacturer confirming the material is unvulcanized, as the two headings carry different duty treatments.
Not automatically. The NESOI (not elsewhere specified or included) qualifier means this heading applies only after ruling out the more specific headings—carbon-black/silica compounds (400510), solutions and dispersions (400520), and camel-back strips (400610). Importers should work through the heading hierarchy before defaulting to 400591.
