HS Code for Large turbojet engine

Large turbojet engines are classified under HS code 8411.12. This classification is based on the mechanical nature of the engine and its thrust capacity. Heading 8411 covers gas turbines, and the first sub-category is dedicated to turbo-jets. A turbo-jet is defined as a gas turbine engine that provides propulsion solely through the reaction of a high-velocity gas stream. Subheading 8411.12 is specifically for those engines that produce a thrust exceeding 25 kN (kilonewtons). This threshold separates large commercial and military jet engines from smaller units used in light aircraft or drones. The classification is determined by the maximum thrust the engine can produce at takeoff under standard sea-level conditions. This code is essential for the aerospace industry and is used for the importation of primary propulsion units for large aircraft.

Products Included

• Commercial airliner jet engines (e.g., for Boeing 737 or Airbus A320)
• High-thrust military fighter jet engines
• Industrial turbojets used for high-speed testing
• Bypass turbofans (classified as turbojets in the HS) exceeding 25 kN
• Afterburning turbojet engines

Common Misclassification

The most frequent misclassification is with HS code 8411.11, which is for turbo-jets with a thrust not exceeding 25 kN. Importers must ensure the thrust rating is correctly converted to kilonewtons. Another common error is confusing turbo-jets with turbo-propellers (8411.21/22). While both are gas turbines, a turbo-propeller uses the turbine to drive a propeller rather than relying on jet exhaust for thrust. Additionally, parts of these engines should not be classified here; they belong under 8411.91. Finally, used or refurbished engines still fall under 8411.12, provided they are functional units.

FAQ

What is the HS code for large turbojet engine?

The HS code for a turbo-jet engine with a thrust exceeding 25 kN is 8411.12.

Are turbofan engines classified under this code?

Yes, for the purposes of the Harmonized System, turbofan engines are treated as turbo-jets and are classified under 8411.11 or 8411.12 based on their thrust.
