HS Code for Turbine generator

The classification of turbine generators under HS code 8502.39 is determined by the General Rules of Interpretation (GRI) and the specific notes of Section XVI of the Harmonized System. Heading 8502 is dedicated to electric generating sets and rotary converters. A generating set is defined as a combination of an electrical generator and a prime mover. The classification within 8502 is primarily determined by the type of prime mover used to drive the generator. Subheadings 8502.11 through 8502.20 are strictly reserved for sets powered by internal combustion piston engines, such as diesel or petrol engines. Since turbine generators utilize steam turbines, gas turbines, or hydraulic turbines—which are rotary engines rather than reciprocating piston engines—they are excluded from those specific subheadings. Furthermore, wind-powered generating sets are specifically carved out into 8502.31. Consequently, turbine-driven sets fall into the residual category 8502.39, which covers \"other\" generating sets. This classification applies whether the units are imported as a single integrated machine or as a functional unit where the components are intended to be connected by pipes or cables. The essential character of the product is the generation of electricity through non-piston mechanical energy. According to GRI 1, the terms of the heading and the section notes are paramount, and since 8502.39 is the most specific description for non-piston, non-wind sets, it is the correct legal classification for these industrial power systems.

Products Included

• Steam turbine generating sets
• Gas turbine generating sets (excluding aircraft engines)
• Hydraulic turbine generating sets
• Geothermal turbine generators
• Combined cycle power plant generating units

Common Misclassification

Turbine generators are frequently confused with the turbines themselves. A steam turbine without a generator is classified under 8406, while a gas turbine alone falls under 8411. Additionally, wind-powered sets must be classified under 8502.31, and any set using a reciprocating piston engine must be placed in 8502.11 through 8502.20 depending on the power output.

FAQ

What is the HS code for turbine generator?

The HS code for a turbine generator set (other than wind-powered) is 8502.39.

Does this code include the turbine and the generator if shipped separately?

If the turbine and generator are imported together as a functional unit to be connected on-site, they are classified together under 8502.39. If imported separately without the other component, they are classified under their respective headings (8406/8411 for turbines or 8501 for generators).
