U.S. exports of Parts for Electrical Resistors, Rheostats & Potentiometers (HS 853390) totaled $5.4M in August 2026.
Importers of Parts for Electrical Resistors, Rheostats & Potentiometers paid $250K in duties in August 2026, an average duty rate of 8.92% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataDedicated parts for resistors, rheostats, and potentiometers — including ceramic and metal composite substrates, resistance elements, and mechanical assemblies — are classified here rather than with the finished devices. The three 10-digit lines distinguish general electric resistor parts (8533900000), variable resistor parts made of ceramic or metal materials (8533904000), and all other electric resistor parts (8533908000). Mexico leads US import supply, consistent with its role as a major assembly hub for finished resistors, where component parts flow across the border as inputs to manufacturing.

A part must be identifiable as exclusively or principally used in the construction or repair of a resistor, rheostat, or potentiometer — for example, a bare resistance element, a ceramic winding form, or a mechanical shaft assembly. Finished resistors with all functional elements present are classified under the appropriate finished-goods heading (853310–853340), not here. Importers should be prepared to provide technical documentation showing the article's intended use as a component.
The US schedule provides a separate 10-digit line (8533904000) for variable resistor parts of ceramic or metal materials, which may carry a different duty rate than the general parts line (8533908000). Importers should verify the applicable rate for each line at the time of entry, as rates can differ and are subject to change.
