HS Code for Large gas turbine

The classification of a large gas turbine under HS code 8411.82 is governed by the General Interpretative Rules (GIR) 1 and 6. Heading 8411 is the specific provision for turbo-jets, turbo-propellers, and other gas turbines. Within this heading, the code 8411.82 is reserved for gas turbines that are not used for aircraft propulsion (which are typically turbo-jets or turbo-propellers) and which possess a power output exceeding 5,000 kW. This classification is determined by the technical specifications of the machine, specifically its rated power output under standard conditions. These turbines operate on the principle of internal combustion, where air is compressed, mixed with fuel, and ignited to drive a turbine rotor. Because the power exceeds the 5,000 kW threshold, it moves past the 8411.81 designation. The classification remains consistent regardless of whether the turbine is intended for electrical power generation, mechanical drive in industrial plants, or marine propulsion, provided it meets the mechanical definition of a gas turbine and the power requirement.

Common Misclassification

This code is frequently confused with HS code 8411.81, which applies to gas turbines with a power output of 5,000 kW or less. Importers must verify the ISO power rating to avoid this error. Additionally, it is often confused with HS code 8406, which covers steam turbines. While both are turbines, 8406 requires an external heat source to produce steam, whereas 8411 involves internal combustion. Another common error involves HS code 8502, which covers electric generating sets. If the turbine is imported already coupled with an alternator, it may be classified as a generating set under 8502 rather than a turbine under 8411.82.

FAQ

What is the HS code for large gas turbine?

The HS code for a gas turbine with a power output exceeding 5,000 kW is 8411.82.

Does this code include the electrical generator?

No, HS code 8411.82 covers the turbine engine itself. If the turbine is integrated with an electrical generator, the entire unit is typically classified under heading 8502 as an electric generating set.
