U.S. imports of Parts for Electric Motors, Generators, Generating Sets & Rotary Converters, N.E.S. (SITC 71690) totaled $370.7M in August 2026, imported from 78 countries.
Importers of Parts for Electric Motors, Generators, Generating Sets & Rotary Converters, N.E.S. paid $67.5M in duties in August 2026, an average duty rate of 18.49% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataDedicated parts — such as stator windings, rotor assemblies, commutators, and brush gear — used solely or principally with electric motors, generators, generating sets, or rotary converters are captured here when no more specific parts heading applies. The 'solely or principally with' standard is a recurring classification challenge: a part that serves multiple machine types may be redirected to a general machinery parts heading. Supply chains for these components are globally distributed, and several categories of electrical machinery parts have faced Section 301 tariff exposure depending on origin.

CBP applies a principal-use test based on the part's design, commercial availability, and the proportion of its actual use in the relevant machines. Parts engineered specifically for generator or motor applications — with matching mounting dimensions, insulation ratings, or OEM part numbers — generally satisfy the test, while generic fasteners or bearings used across many machine types typically do not.
Generally yes, provided the stator is designed solely or principally for use in an electric generator or motor. Importers should retain OEM documentation or engineering specifications confirming the dedicated application, as CBP may request evidence to distinguish purpose-built generator stators from general electromagnetic components.
