About heading 8411

Turbojets, turbopropellers and other gas turbines, and parts thereof

Heading 8411 covers turbojets, turbopropellers and other gas turbines, plus their parts. It is split first by engine type, then by thrust or power, and then by aircraft turbine versus other use. Parts are split by the type of engine and by whether they are cast-iron parts in a rough state or other parts.
