HS Code for Small turbojet engine

Turbojet engines with a thrust not exceeding 25 kN are classified under HS code 8411.11. A turbojet is a type of gas turbine engine that works by compressing air, mixing it with fuel, igniting the mixture, and exhausting the high-velocity gases to produce thrust. The classification under 8411.11 is strictly based on the thrust capacity. If the engine produces more than 25 kN of thrust, it is classified under 8411.12. These smaller engines are frequently found in small executive jets, unmanned aerial vehicles (UAVs), or as auxiliary power units in larger aircraft. The distinction is vital for regulatory compliance and monitoring the trade of dual-use technologies. The thrust measurement must be taken at take-off power in a static position at sea level, following standard atmospheric conditions as defined by international aviation standards.

Common Misclassification

The most common misclassification occurs between turbojets (8411.11) and turboprops (8411.21). While both are gas turbines, a turbojet produces thrust through exhaust gases, whereas a turboprop uses the turbine to drive a propeller. Additionally, engines exceeding 25 kN must be classified under 8411.12. Importers sometimes confuse these with turbo-fans, but for HS purposes, turbo-fans are generally classified under the same subheadings as turbo-jets (8411.11 or 8411.12) based on their thrust.

FAQ

What is the HS code for Small turbojet engine?

The HS code for a turbojet engine with a thrust not exceeding 25 kN is 8411.11.

How is thrust measured for HS classification?

Thrust is measured as the maximum thrust the engine can produce at sea level in a static environment, usually expressed in kilonewtons (kN).
