HS Code 8502 — Electric Generating Sets and Rotary Converters

This code covers combinations of an electric generator and a prime mover, such as a diesel or petrol engine. These units are commonly used as backup power sources on construction sites, in hospitals, or for off-grid power.

What's included

Diesel generating sets
Gas-turbine generating sets
Wind-powered generating sets
Rotary converters

What's excluded

Separate generators → use 8501 (Generators without a prime mover are in 8501.)
Central heating boilers → use 8403 (Heating equipment is handled under thermal machinery headings.)

Common examples

50kVA diesel backup generator
Portable petrol inverter generator
Utility-scale wind turbine nacelle
Rotary phase converter

Frequently asked questions

Are wind turbines under 8502?

Yes, if they include the generator and the blades/hub as a set, they are classified here as wind-powered generating sets.

Trade & shipping notes

Typical duty range: 0% - 5%
Documentation: EPA/environmental emissions certificates are often required for engine-driven sets.
Typical shipping mode: FCL
Top exporters: China, Germany, United Kingdom, United States
Top importers: United States, Nigeria, Canada, Saudi Arabia

Key takeaway

Differentiated primarily by the type of prime mover (diesel, petrol, gas, or wind).
