HS Code for Small turboprop engine

HS code 8411.21 applies to turbo-propellers with a power output not exceeding 1100 kW. Turboprop engines differ from turbojets in that the gas turbine's energy is primarily used to drive a propeller through a reduction gearbox, rather than providing thrust directly from the exhaust. The 1100 kW threshold (roughly 1475 horsepower) separates smaller turboprop engines used in light aircraft and utility planes from the more powerful engines used in large regional transport aircraft. Accurate classification requires verification of the maximum continuous power rating under standard atmospheric conditions. These engines are favored for short-haul flights and cargo transport due to their fuel efficiency at lower altitudes and speeds compared to turbojets. The classification covers the engine itself, including the reduction gear, but typically excludes the propeller, which may be classified separately under 8803.

Products Included

• Light aircraft turboprop engines (≤ 1100kW)
• Utility aircraft propulsion units
• Small maritime gas turbines (propeller driven)
• Turboprop engines for agricultural planes

Common Misclassification

Turboprop engines are often confused with turbojet engines (8411.11). The key difference is the method of propulsion: 8411.21 is for engines driving a propeller, while 8411.11 is for reaction-based thrust. Another common error is misclassifying engines that exceed the 1100 kW limit; these must be placed under 8411.22. Furthermore, turboshaft engines (used in helicopters) are classified under 8411.81 or 8411.82, even though they share similar gas turbine architectures.

FAQ

What is the HS code for Small turboprop engine?

The HS code for a turbo-propeller engine with a power not exceeding 1100 kW is 8411.21.

Does this code include the aircraft propeller?

No, the propeller itself is usually classified under heading 8803 as a part of an aircraft. HS code 8411.21 refers specifically to the gas turbine engine unit.
