U.S. imports of Articles of Unhardened Noncellular Vulcanized Rubber, NES (SITC 62999) totaled $425.0M in August 2026, imported from 125 countries.
Importers of Articles of Unhardened Noncellular Vulcanized Rubber, NES paid $43.5M in duties in August 2026, an average duty rate of 10.32% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataSolid (noncellular) vulcanized rubber articles not elsewhere specified serve as a catch-all for a wide range of engineered rubber components — from mechanical seals and vibration dampeners to conveyor belt accessories — used across industrial, automotive, and infrastructure sectors. Classification here requires confirming the rubber is vulcanized but not hardened into ebonite, and that no more specific heading applies. The NES designation means customs examiners may scrutinize whether a more precise tariff provision exists before accepting this classification.

Importers should obtain a material composition certificate confirming vulcanization and the absence of cellular structure, and then systematically rule out more specific headings (e.g., rubber tubing, belting, gaskets with dedicated codes). A binding ruling request to CBP can provide certainty when the classification is genuinely ambiguous.
For purely industrial rubber articles, no mandatory admissibility agency review applies. However, if the article contacts food or is used in a medical device context, FDA oversight may be triggered based on end use rather than the rubber's vulcanization state.
