Heading 8411

Turbojets, turbopropellers and other gas turbines, and parts thereof

27 declarable lines

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.

Products in this heading

Aircraft turbojet engine under 25 kN thrust
Aircraft turbopropeller engine under 1,100 kW
Industrial gas turbine under 5,000 kW
Gas turbine rotor and spindle assembly
Cast-iron turbine casing not advanced beyond cleaning

Turbine parts for nonaircraft gas turbines

How to choose the right subheading

Identify whether the machine is a turbojet, a turbopropeller, or another gas turbine.
For turbojets, check thrust relative to 25 kN; for turbopropellers, check power relative to 1,100 kW.
For other gas turbines, check power relative to 5,000 kW.
Decide whether the article is an aircraft turbine or for another use.
For parts, identify the parent engine and whether the part is a cast-iron part not advanced beyond cleaning or another part.

Frequently asked questions

What is the HTS code for a small aircraft turbojet engine?

A turbojet with thrust not exceeding 25 kN for aircraft turbines is 8411.11.40.00, with a general (MFN) duty rate of Free.

What is the duty on nonaircraft gas turbine rotor assemblies?

Rotors or spindles and rotor or spindle assemblies for nonaircraft gas turbines are classified in 8411.99.90.30, with a general (MFN) duty rate of 2.4%.

How do I classify cast-iron turbojet parts that are not advanced beyond cleaning?

Cast-iron parts of turbojets or turbopropellers not advanced beyond cleaning are classified by use: 8411.91.10.40 for parts of nonaircraft turbines, general (MFN) Free, and 8411.91.10.60 for parts of aircraft turbines for use in civil aircraft, general (MFN) Free.
