Last updated: August 2026 dataCellular (foam) vulcanized rubber articles not elsewhere specified serve as vibration-damping pads, thermal insulation strips, gasketing foam, and cushioning components across automotive, construction, and HVAC sectors. The heading resolves to a single US tariff line (4016100000), so classification disputes typically center on whether the rubber is truly cellular in structure versus solid, and whether the article belongs in a more specific heading. Mexico and Canada together account for a substantial share of US imports, reflecting integrated North American supply chains in automotive and building-products manufacturing.

Cellular rubber contains a network of cells — open, closed, or mixed — formed during vulcanization, giving it a foam-like structure. The distinction matters because cellular rubber articles fall under 401610, while solid vulcanized rubber articles of the same shape would fall under 401693 (seals/gaskets) or 401699 (NESOI). CBP may request material test data or cross-sections to confirm cellular structure when the article's appearance is ambiguous.
Imports from Mexico may qualify for preferential tariff treatment under USMCA, provided the goods meet the applicable rules of origin, including any required regional value content or tariff-shift criteria. Importers should obtain a USMCA certification of origin from the supplier and retain it for five years as required by CBP regulations.
