U.S. imports of generators for internal combustion engines (other than starter-generators) (HS 851150) totaled $120.0M in July 2026, traded with 62 countries.
Importers of Generators for Internal Combustion Engines (Other Than Starter-Generators) paid $7.3M in duties in July 2026 — an effective duty rate of 18% on $41.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataAlternators and other generators designed to produce electrical power in conjunction with internal combustion engines — excluding dual-purpose starter-generators — classify under a single 10-digit line (8511500000). Automotive alternators dominate import volume in this heading, serving both OEM assembly lines and a large aftermarket replacement market. As with other ignition and starting equipment, goods of Chinese origin are subject to Section 301 tariffs, making origin documentation and first-sale valuation strategies important cost-management tools for high-volume importers.

Generally yes — an alternator with an internally mounted voltage regulator is classified by its essential character as a generator for internal combustion engines and remains under 8511500000. The integrated regulator does not shift classification to the voltage regulator lines under 851180, provided the generator function is the primary purpose of the assembly. Importers with complex integrated units should verify against applicable CBP rulings.
Remanufactured alternators carry the same HTS classification as new units but require careful valuation. Core charges, warranty allowances, and the value of the remanufacturing process must be properly accounted for in the declared customs value. CBP has issued guidance on remanufactured goods valuation, and importers in the automotive aftermarket should work with a licensed broker familiar with these rules.
