SITCSection 7
U.S. imports of parts for electrical resistors (excluding heating resistors) (SITC 77238) totaled $2.7M in April 2026, traded with 28 countries.
Importers of Parts for Electrical Resistors (Excluding Heating Resistors) paid $196K in duties in April 2026 — an effective duty rate of 16% on $1.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataDedicated parts for rheostats, potentiometers, and other non-heating electrical resistors — such as resistance elements, wiper contacts, shafts, and housings — are traded separately from finished resistors and fall under this heading. The explicit exclusion of heating resistor parts is a key classification boundary: elements intended for electric heaters, ovens, or similar thermal applications belong elsewhere. For importers supplying resistor repair depots or OEM assembly operations, correctly separating parts from finished assemblies is essential, as the two can carry different duty rates and Section 301 exposure. Detailed parts lists and assembly diagrams are the most effective documentation for supporting classification at entry.

The key is demonstrating the part's intended function: a resistance element designed for a potentiometer or rheostat — not for generating heat — should be supported by a technical datasheet, assembly drawing, or purchase order referencing the parent resistor model. If the part could plausibly serve a heating application, a binding ruling request to CBP before importation is advisable.
Yes. The heading covers parts specifically designed for non-heating electrical resistors regardless of the material of the part itself. A metal shaft or wiper contact that is identifiable as a part for a potentiometer or rheostat qualifies here. The critical factor is that the part must be dedicated to a resistor function rather than being a general-purpose mechanical component.
