Heading 8502

Electric generating sets and rotary converters

12 declarable lines

Heading 8502 covers electric generating sets and electric rotary converters. It splits generating sets by engine or power source: compression-ignition engines, spark-ignition engines, and other generating sets such as wind or steam turbine. Output in kVA decides several subheadings, and rotary converters are classified separately.

Products in this heading

Diesel generator set rated 50 kVA
Diesel generator set rated 200 kVA
Diesel generator set rated 500 kVA
Portable gasoline generator set rated 5 kVA
Wind-powered generating set
Steam turbine generating set
Electric rotary converter

How to choose the right subheading

Identify whether the item is a generating set or an electric rotary converter.
For generating sets, determine the power source: compression-ignition engine, spark-ignition engine, wind, steam turbine, or other.
For diesel and semi-diesel sets, check output in kVA against the 75, 375, and 1,000 kVA breakpoints.
For spark-ignition sets, check output in kVA against the 1.875, 6.25, and 75 kVA breakpoints.
Confirm the item is a complete generating set, not a separate motor, battery, converter, or part.

Often confused with

Standalone electric motors
Heading 8502 covers generating sets, not motors sold on their own.
Heading 8501
Electric storage batteries
Batteries are classified as storage batteries, even when used with power equipment.
Heading 8507
Uninterruptible power supplies that are static converters
Static converters and rectifiers are not rotary converters or generating sets.
Heading 8504
Solar panels and photovoltaic cells
Photovoltaic cells and modules are semiconductor devices, not generating sets of 8502.
Heading 8541
