Last updated: April 2026 dataFoam-structured vulcanized rubber articles — including open- and closed-cell sponge rubber components — fall here when not classified under a more specific heading. The cellular structure distinguishes these goods from solid rubber articles, affecting both compressibility specifications and end-use suitability in sealing, cushioning, and insulation applications across automotive, construction, and consumer goods sectors. Importers should confirm that the rubber has been vulcanized but not hardened (ebonite), as that distinction drives classification between competing headings.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Cellular vulcanized rubber has a foam or sponge-like internal structure with air pockets, giving it compressibility and cushioning properties. Noncellular vulcanized rubber is solid throughout. This structural difference is the primary classification dividing line between SITC 62992 and 62999, and misclassification can affect applicable duty rates.
Common examples include foam rubber gaskets, weatherstripping, padding, and cushioning components that are not specifically described elsewhere. Articles that are more specifically described — such as rubber gloves, tires, or tubing — are classified under their own dedicated headings rather than this residual NES category.
