Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If turbochargers or non-generating gas turbines
Heading 8411 covers turbines not coupled to generators for electricity production
If general other generating sets if steam power not specified
Statistical suffixes distinguish steam (.40) from other turbine types within 8502.39
If imported as automatic control panels only
Control systems for generators classify separately under 9032, not complete sets
