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
In plain English
This category covers industrial and laboratory electric furnaces, ovens, and other heating equipment used for heat treating materials. The items are divided based on their heating method, such as resistance, induction, dielectric loss, electron beams, plasma, or vacuum arcs. Specific distinctions are made for equipment used in semiconductor manufacturing and for hot isostatic presses. The final section includes parts for these industrial or laboratory machines.
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.

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.
