HS Code 8502.39 – Electric generating sets; (excluding those with spark-ignition or compression-ignition internal combustion piston engines), other than wind powered
HS code 8502.39 is the 6-digit subheading for electric generating sets, (excluding those with spark-ignition or compression-ignition internal combustion piston engines), other than wind powered. It is used for small-scale hydroelectric generating sets, geothermal generating sets, tidal power generators, wave energy converters and biomass gasifier generators.
What HS 8502.39 covers
This HS code is a residual category for electric generating sets, excluding those powered by spark-ignition or compression-ignition internal combustion piston engines, and also excluding wind-powered sets. This 'other' category encompasses a diverse range of alternative and renewable energy generating sets. This includes small-scale hydroelectric, geothermal, tidal, wave, and biomass-fueled generating sets, often representing niche or emerging technologies. Importers and exporters are typically specialized energy companies, research institutions, and distributors catering to specific environmental or experimental applications. Key trade factors include the specific energy source utilized, conversion efficiency, environmental impact, scalability, and integration with existing power infrastructure. These generators are crucial for diversifying energy portfolios beyond conventional and common renewable sources.

Codes often confused with 8502.39
Common mistake. As a 'basket' code, it's often confused with more specific generating sets if the power source isn't clearly defined. It's crucial to ensure it's not wind-powered (850231) or internal combustion (85021x, 850220).
Top exporters and importers of HS code 850239, 2025
In 2025, the largest exporter of HS code 850239 in UN Comtrade data was Sweden, with 17% of world exports; the largest importer in UN Comtrade data was Kazakhstan, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
