U.S. exports of Industrial & Laboratory Induction or Dielectric Heating Equipment (HS 851440) totaled $13.7M in August 2026.
Importers of Industrial & Laboratory Induction or Dielectric Heating Equipment paid $620K in duties in August 2026, an average duty rate of 12.69% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataInduction heating equipment — used for metal hardening, brazing, forging preheat, and crystal growth — and dielectric heating equipment for processing plastics, wood composites, and food packaging materials both fall under this heading, classified together at the 10-digit level under 8514400000. Germany and France are the leading US suppliers, reflecting European dominance in precision induction power supply and coil technology. Canada, also a top supplier, benefits from integrated North American manufacturing supply chains. Unlike furnace-type equipment, induction and dielectric systems are often sold as modular power-supply-plus-applicator packages, which can raise classification questions about whether the complete system or its components are being imported.

If the power supply and coil are imported together as a functional system, the complete unit is classified under 851440. When imported separately, each component must be classified on its own merits: the power supply may fall under a different heading for electronic power conversion equipment, while the coil or applicator could be classified as a part under 851490. Importers should assess whether GRI 2(a) incomplete-article rules or parts provisions apply, and consult a licensed customs broker for complex split shipments.
Dielectric heating equipment under 851440 operates at radio frequencies (typically 1–100 MHz) to heat non-conductive materials such as plastics or wood through molecular friction, and is designed for industrial continuous or batch processing. Microwave ovens, which operate at microwave frequencies (typically 2.45 GHz), are classified separately under heading 8516. The operating frequency band and industrial design intent are the key distinguishing factors.
