HS Code 8501.34 – Electric motors and generators; DC, of an output exceeding 375kW
HS code 8501.34 is the 6-digit subheading for electric motors and generators, DC, of an output exceeding 375kW. It is used for ultra-heavy duty industrial DC motors, large marine propulsion DC motors, steel mill main drive DC motors, mining dragline DC motors and large DC generators for power plants.
What HS 8501.34 covers
This category encompasses very high-power DC electric motors and generators, with an output exceeding 375kW. These are the titans of industrial machinery, essential for the most demanding applications such as main drives in large steel mills, ultra-heavy-duty mining equipment, large marine vessels, and specialized power generation. International trade in these massive machines is highly specialized and often project-based, involving a limited number of global manufacturers and buyers. Importers are typically countries undertaking major industrial infrastructure projects or operating heavy industries, while exporters are nations with cutting-edge engineering and manufacturing capabilities for heavy electrical equipment. Customization and long-term operational reliability are paramount in this segment.

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).
