HS Code 8514.20 – Furnaces and ovens; electric, for industrial or laboratory use, functioning by induction or dielectric loss
HS code 8514.20 is the 6-digit subheading for furnaces and ovens, electric, for industrial or laboratory use, functioning by induction or dielectric loss. It is used for induction melting furnaces, induction hardening machines, dielectric heating ovens, microwave industrial ovens and RF heating equipment.
What HS 8514.20 covers
This HS code encompasses electric furnaces and ovens for industrial or laboratory use that operate by induction or dielectric loss. These heating methods are highly efficient and precise, making them suitable for a wide range of applications across various industries. Induction furnaces are commonly used in metallurgy for melting, forging, and heat treatment of metals, while dielectric heating is prevalent in plastics processing, woodworking, and the food industry for rapid and uniform heating. Exporters include specialized industrial equipment manufacturers, with importers spanning manufacturing sectors globally. Key aspects of this trade involve the energy efficiency of these systems, their ability to provide localized and controlled heating, and their role in modernizing industrial processes. The market is driven by the need for faster, more precise, and environmentally friendly heating solutions in manufacturing.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
