HS Code 8411.99 – Turbines; parts of gas turbines (excluding turbo-jets and turbo-propellers)
HS code 8411.99 is the 6-digit subheading for turbines, parts of gas turbines (excluding turbo-jets and turbo-propellers). It is used for industrial gas turbine blades, compressor vanes, combustor liners, rotor assemblies and stator components.
What HS 8411.99 covers
This HS code covers parts for industrial gas turbines, which are distinct from aircraft engines and are primarily used in power generation, oil and gas, and other heavy industries. These components are vital for the manufacturing, assembly, maintenance, and repair of both large and small industrial gas turbines worldwide. The international trade in these parts is driven by the continuous operational and servicing requirements of power plants, industrial facilities, and marine vessels. Importers are typically turbine manufacturers, power utility companies, oil & gas operators, and specialized industrial MRO service providers. Exporters are often the original turbine equipment manufacturers or their approved component suppliers. The market demands high precision, durability, and often custom-engineered parts to ensure the reliability and longevity of these critical industrial assets.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
