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
6-digit subheadings (8)
Official HS 2022 subheading texts. National tariff schedules subdivide these further (8-10 digit lines) and set the actual duty rates.
Furnaces and ovens; electric, for industrial or laboratory use, resistance heated; hot isostatic presses
Furnaces and ovens; electric, for industrial or laboratory use, resistance heated; other than hot isostatic presses, for the manufacture of semiconductor devices on semiconductor wafers
Furnaces and ovens; electric, for industrial or laboratory use, functioning by induction or dielectric loss
Furnaces and ovens; electric, for industrial or laboratory use, other than those functioning by induction, dielectric loss or resistance heated, electron beam furnaces
Furnaces and ovens; electric, for industrial or laboratory use, other than those functioning by induction, dielectric loss or resistance heated, plasma and vacuum arc furnaces
Furnaces and ovens; electric, for industrial or laboratory use, other than those functioning by induction, dielectric loss or resistance heated, other than electron beam, plasma or vacuum arc furnaces
Heating equipment; for the heat treatment of materials by induction or dielectric loss, industrial or laboratory, other than furnaces and ovens
Furnaces, ovens and heating equipment; parts of the industrial or laboratory equipment of heading no. 8514
Chapter 85 classification notes
Frequent misclassification in this chapter
Many importers confuse 85 (electrical) and 84 (mechanical). A device with both elements usually classifies by principal function. Chargers and adapters classified separately from the device they charge.
Classification certainty
The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
