Product classification
HS code for DC generator: 8501.33
Electric motors and generators, DC, of an output exceeding 75kW but not exceeding 375kW.
Classification of DC generator under HS 8501.33
The classification of a DC generator with an output exceeding 75kW but not exceeding 375kW falls under HS code 8501.33. This determination is based on the General Rules for the Interpretation (GIR) of the Harmonized System, specifically GIR 1 and 6. Heading 8501 encompasses electric motors and generators, excluding generating sets. The classification process first identifies the machine as a generator, then distinguishes it as a Direct Current (DC) type rather than Alternating Current (AC). Finally, the specific subheading is determined by the rated power output. For units producing more than 75kW but staying within the 375kW threshold, 8501.33 is the mandatory code. This classification applies regardless of whether the generator is intended for industrial power plants, marine applications, or heavy machinery, provided it functions as a standalone DC generator within the specified electrical parameters. The power rating is usually determined by the manufacturer's continuous duty rating as indicated on the nameplate.

Codes often confused with 8501.33
Common mistake. This code is frequently confused with 8501.32, which covers DC generators with an output exceeding 750W but not exceeding 75kW. Conversely, units exceeding 375kW must be classified under 8501.34. Another common error is using 8501.61, which is reserved for AC generators (alternators). If the generator is imported as part of a set with a prime mover (like a diesel engine), it must be classified under heading 8502 rather than 8501.
Top exporters and importers of HS 850133 (the code used for DC generator), 2025
In 2025, the largest exporter of HS 850133 (the code used for DC generator) in UN Comtrade data was China, with 17% of world exports; the largest importer in UN Comtrade data was India, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 850133, not only DC generator.

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).

Questions about DC generator
What is the HS code for DC generator?
The HS code for DC generator is 850133 (Electric motors and generators; DC, of an output exceeding 75kW but not exceeding 375kW). The HS code for a DC generator depends on its power output. For those exceeding 75kW but not exceeding 375kW, the code is 8501.33.
How do I classify DC generator for customs?
DC generator is classified under HS code 850133 — Electric motors and generators; DC, of an output exceeding 75kW but not exceeding 375kW. This is a 6-digit subheading level code.
Does this code include DC motors?
Yes, heading 8501.33 covers both DC motors and DC generators within the specified power range of 75kW to 375kW.
Which countries are the top exporters of DC generator (HS 850133)?
In 2025, the top exporters of HS 850133 (the code used for DC generator) in UN Comtrade data were China ($87M, 17% of world exports), Germany ($81M) and Canada ($59M). World exports came to about $520M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
