SITCSection 6
U.S. imports of vulcanized unhardened cellular rubber — plates, sheets, strip, rods & profile shapes (SITC 62132) totaled $6.7M in April 2026, traded with 45 countries.
Importers of Vulcanized Unhardened Cellular Rubber — Plates, Sheets, Strip, Rods & Profile Shapes paid $774K in duties in April 2026 — an effective duty rate of 16% on $5.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataCellular (foam) rubber in its unhardened vulcanized form — supplied as flat stock or extruded profiles — is the material of choice for thermal and acoustic insulation, gasketing, and cushioning across construction, HVAC, and automotive interiors. The cellular structure, created by incorporating blowing agents during compounding, distinguishes this heading from solid (noncellular) vulcanized rubber sheet, and the distinction is commercially significant because density, compression set, and thermal conductivity differ substantially between the two forms. Profile shapes in this category include door seals, window glazing strips, and pipe-insulation sections that are cut to length from continuous extrusions.

Cellular rubber contains a network of open or closed cells formed by gas expansion during vulcanization, giving it a foam-like structure with lower density than solid rubber. The cellular/noncellular distinction is a primary classification split — cellular forms fall here (62132) while solid vulcanized rubber plates and sheets fall under the noncellular heading (62133), and the two carry different duty treatments.
Yes — plates, sheets, strip, rods, and profile shapes are all grouped together provided the material is unhardened vulcanized cellular rubber. However, if the profile has been further fabricated into a finished article (e.g., a pre-cut door seal with adhesive backing), it may reclassify to a finished rubber article heading, so the degree of further processing should be evaluated before import.
