U.S. imports of vulcanized rubber transmission belts & belting, nesoi (HS 401039) totaled $23.1M in August 2026, imported from 57 countries.
Importers of Vulcanized Rubber Transmission Belts & Belting, NESOI paid $2.0M in duties in August 2026, an effective tariff rate of 8.77% of the $23.1M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataTransmission belts and belting of vulcanized rubber that fall outside the specific V-belt and synchronous-belt circumference ranges — or that use construction types not captured by those headings — are classified here, covering a wide range of flat belts, round belts, and specialty drive belting used in conveyors, machine tools, and light industrial equipment. Mexico and India are the leading suppliers, with Japan and Germany also prominent, reflecting both USMCA-integrated production and the global breadth of the rubber-belting industry. Eight 10-digit lines differentiate by V-belt versus other belt type, textile fiber composition, and belt width, making this the most structurally complex heading in the rubber-belting group.

401039 captures V-belts and other transmission belts whose circumference falls outside the 60–240 cm ranges covered by headings 401031–401034, as well as flat belts, round belts, and other non-trapezoidal, non-synchronous drive belting. It also serves as the residual for any transmission belt construction not specifically described elsewhere in heading 4010.
For lines that distinguish vegetable-fiber from man-made-fiber constructions, CBP expects a manufacturer's fiber-composition certificate or test report confirming the predominant textile fiber by weight. For lines that separate belts wider than 20 cm from narrower ones, a dimensional specification sheet showing finished belt width should accompany the entry documentation.
