Last updated: August 2026 dataV-ribbed transmission belts in the 60–180 cm circumference range are the dominant belt type in automotive accessory drives — powering alternators, power-steering pumps, and air-conditioning compressors on passenger cars and light trucks. The US schedule separates textile-reinforced constructions (4010313000) from other V-ribbed belts (4010316000), with a legacy combined line (4010310000) also present. Mexico leads US supply by a wide margin, reflecting deep automotive-supply-chain integration under USMCA, with Japan and Germany also significant sources. Importers should verify whether USMCA rules-of-origin criteria are met, as the automotive aftermarket draws from multiple origins.

A V-ribbed belt has multiple longitudinal ribs on its inner surface and a flat or slightly contoured outer surface, whereas a standard V-belt has a single trapezoidal cross-section throughout. CBP classifies them separately: V-ribbed belts fall under 401031 (60–180 cm) or 401033 (180–240 cm), while non-ribbed V-belts of the same circumference ranges fall under 401032 or 401034.
Belts manufactured in Mexico may qualify for USMCA preferential tariff treatment if they satisfy the applicable rules of origin, including any required regional value content or tariff-shift criteria. Importers must obtain a valid USMCA certification of origin from the producer or exporter and retain it for post-entry audit purposes.
