HS Code for Small gas turbine

The HS code 8411.81 is applied to gas turbines with a power output not exceeding 5,000 kW, excluding turbo-jets and turbo-propellers. This classification is situated within Chapter 84, which deals with nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8411 covers turbo-jets, turbo-propellers, and other gas turbines. The distinction between "other gas turbines" and aviation-specific turbines is crucial for correct classification. Subheading 8411.81 specifically targets industrial or marine gas turbines that fall below the 5,000 kW threshold. These units operate by compressing air, mixing it with fuel, and igniting it to drive a turbine. The classification depends on the mechanical function and the power rating. It is essential to distinguish these from steam turbines or internal combustion engines. The classification is guided by the technical parameters of the turbine's output, usually measured in kilowatts (kW) or megawatts (MW). For customs purposes, the power rating must be the continuous rated power as specified by the manufacturer's technical documentation.

Products Included

Common Misclassification

Small gas turbines are often confused with turbo-jets (8411.11) or turbo-propellers (8411.21). However, those codes are strictly for aircraft propulsion. Another common misclassification is HS code 8411.82, which is for gas turbines with a power exceeding 5,000 kW. Additionally, if the turbine is part of an electric generating set, it should be classified under heading 8502 rather than 8411. Steam turbines, which operate on a different thermodynamic cycle, belong under heading 8406.

FAQ

What is the HS code for Small gas turbine?

The HS code for a gas turbine (excluding turbo-jets and turbo-propellers) with a power not exceeding 5,000 kW is 8411.81.

Does this code include the generator?

No, if the turbine is coupled with a generator, the entire unit is classified as a generating set under heading 8502. Code 8411.81 is for the turbine itself.
