SITCSection 7
U.S. imports of electric heating resistors (other than carbon) (SITC 77588) totaled $78.9M in April 2026, traded with 54 countries.
Importers of Electric Heating Resistors (Other Than Carbon) paid $3.4M in duties in April 2026 — an effective duty rate of 13% on $26.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataNon-carbon electric heating resistors — including wire-wound, thick-film, and ceramic-element types used in industrial furnaces, HVAC systems, medical equipment, and consumer appliances — are a critical intermediate input across multiple manufacturing sectors. Unlike finished consumer appliances, these components are primarily evaluated on electrical specifications such as resistance value, wattage rating, and temperature coefficient, which drive both classification and procurement decisions. Many resistor types used in industrial or defense applications may also be subject to Buy American or specialty procurement requirements when incorporated into government-end-use products.

Electric heating resistors classified here are designed to convert electrical energy into heat as their primary function, whereas electronic fixed resistors are designed to control current in circuits. The distinction turns on the resistor's construction, power rating, and intended application; high-wattage, thermally robust units used in heating elements are classified differently from low-power circuit resistors. Importers should document the end-use application and wattage specifications to support the declared classification.
Key specifications include resistance value (ohms), power rating (watts), operating temperature range, material composition of the resistance element (e.g., nichrome, stainless steel, ceramic), and form factor (tubular, flat, cartridge). These parameters affect both the correct tariff classification and compatibility with the end-use equipment, so full technical datasheets from the manufacturer should accompany each shipment.
