U.S. imports of Electric Heating Resistors (HS 851680) totaled $86.5M in August 2026, imported from 58 countries.
Importers of Electric Heating Resistors paid $4.1M in duties in August 2026, an average duty rate of 4.92% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataElectric heating resistors are a critical industrial and aerospace input, used in applications ranging from anti-icing and de-icing systems to industrial process heating and consumer appliance elements. The US schedule distinguishes resistors specifically designed for anti-icing and de-icing (8516804000) from general-purpose heating resistors (8516808000), a split that reflects the aerospace and defense procurement channel for the former. Mexico leads US imports under this heading, followed by Vietnam and Japan — a supplier mix that spans both high-volume manufacturing and precision engineering. Unlike finished appliances in the broader 8516 heading, heating resistors are purely industrial components and do not trigger mandatory admissibility review by a regulatory agency.

Tariff line 8516804000 covers heating resistors specifically designed for anti-icing or de-icing applications — typically aerospace wing heaters, aircraft pitot tube heaters, or ground-vehicle de-icing elements. General-purpose heating resistors used in appliances, industrial equipment, or process heating fall under 8516808000. The intended end-use and design specification are the primary classification determinants; importers should retain technical datasheets documenting the resistor's rated application.
Heating resistors originating in China may be subject to Section 301 tariffs. Resistors from other major suppliers such as Mexico and Vietnam are not currently subject to Section 301 measures, though importers should verify origin and applicable duty treatment at the time of entry, as trade-remedy orders can change. A licensed customs broker can confirm current applicability.
