U.S. imports of cellular vulcanized rubber rods & profile shapes (HS 400819) totaled $1.3M in April 2026, traded with 37 countries.
Last updated: April 2026 dataExtruded and molded cellular (foam/sponge) rubber in rod and profile-shape form—door seals, window gaskets, edge trims, and similar cross-sections—classifies under heading 400819, which the US schedule breaks into four 10-digit lines distinguishing natural-rubber profile shapes (4008192000), other natural-rubber shapes (4008194000), non-natural profile shapes (4008196000), and other non-natural shapes (4008198000). China is the leading US supplier, followed by Germany and Spain, reflecting both high-volume commodity production and precision-engineered specialty profiles. Importers sourcing from China should confirm Section 301 tariff applicability at the specific 10-digit line level.

Profile shapes (4008192000 and 4008196000) are continuous extruded cross-sections—such as D-seals, P-seals, or T-profiles—designed to be cut to length. 'Other shapes' (4008194000 and 4008198000) covers molded or cut cellular rubber articles like rings, discs, and custom-molded pieces that do not fit the continuous-profile description. Correct line selection depends on the manufacturing method and the article's geometry.
Composite cellular rubber profiles are classified based on the constituent material that imparts the essential character, typically the predominant rubber type by weight or function. If the layers are inseparable and the predominant polymer cannot be determined, the importer should seek a binding ruling from CBP, as misclassification across the natural/non-natural lines can affect duty liability.
