SITCSection 7
U.S. imports of induction or dielectric heating equipment (not elsewhere specified) (SITC 74134) totaled $4.0M in April 2026, traded with 28 countries.
Importers of Induction or Dielectric Heating Equipment (Not Elsewhere Specified) paid $402K in duties in April 2026 — an effective duty rate of 11% on $3.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Induction or Dielectric Heating Equipment (Not Elsewhere Specified) imports of $4.0M in April 2026 ran 17% below the year-to-date monthly average of $4.9M.
Last updated: April 2026 dataIndustrial induction and dielectric heating equipment that is not a complete furnace or oven—such as inline induction heaters for pipe bending, seam-welding units, and RF preheating stations integrated into production lines—is captured here as a residual category for non-furnace electromagnetic heating apparatus. These systems are widely deployed in automotive body assembly, packaging-seal applications, and composite-material curing, where contactless, rapid heating is integrated directly into continuous manufacturing processes. The distinction from heading 74132 (complete furnaces and ovens) rests on whether the equipment constitutes a self-contained thermal processing unit or a heating module embedded in a larger production system. Importers of integrated production-line equipment should carefully assess whether the heating module or the overall machine drives classification.

The key distinction is functional completeness: a furnace or oven (74132) is a self-contained thermal processing chamber designed to heat workpieces placed within it, while the equipment here (74134) typically delivers induction or dielectric energy as a process step within a larger machine or production line—such as an induction coil station on a tube-forming line—without constituting a standalone furnace enclosure.
Induction cap-sealing heads that generate electromagnetic energy to bond foil liners to container openings are generally classified here when imported as standalone units, since they are induction heating devices that are not furnaces or ovens. However, when the sealing head is imported as an integral part of a complete filling-and-sealing machine, the classification of the entire machine may govern. A component-level analysis is recommended for integrated packaging systems.
