About heading 8514
Industrial or laboratory electric furnaces and ovens (including those functioning by induction or dielectric loss); other industrial or laboratory equipment for the heat treatment of materials by induction or dielectric loss; parts thereof
Heading 8514 covers industrial and laboratory electric furnaces and ovens, plus other equipment that heats materials by induction or dielectric loss. It is split first by heating method (resistance, induction or dielectric loss, electron beam, plasma and vacuum arc, other), then by end use, with separate lines for parts. Most industrial lines carry a general (MFN) rate of Free or 1.3%, while microwave ovens and microwave oven parts are dutiable.

Frequently asked questions
What is the HTS code for an industrial resistance heated furnace?
Resistance heated furnaces other than hot isostatic presses are classified under 8514.19.00.00, which carries a general (MFN) rate of Free. Hot isostatic presses use 8514.11.00.00, also Free.
What is the duty on an industrial microwave oven?
Industrial microwave ovens for making hot drinks or for cooking or heating food fall under 8514.20.40.00 at a general (MFN) rate of 4%. Other microwave ovens use 8514.20.60.00 at 4.2%.
How do I classify an electron beam furnace used to make printed circuits?
If it is of a kind used solely or principally for the manufacture of printed circuits or printed circuit assemblies, classify it under 8514.31.10.00, which is Free. Other electron beam furnaces go under 8514.31.90.00 at 1.3%.
