HS Code 8412.90 – Engines; parts, for engines and motors of heading no. 8412
HS code 8412.90 is the 6-digit subheading for engines, parts, for engines and motors of heading no. 8412. It is used for hydraulic motor shafts, pneumatic cylinder seals, vane motor rotors, piston rings for hydraulic motors and gear sets for hydraulic motors.
What HS 8412.90 covers
This HS code covers parts specifically designed for the engines and motors classified under heading 8412, which includes hydraulic, pneumatic, and other non-electric engines and motors. This is a critical category for the maintenance, repair, and manufacturing supply chains of industrial machinery worldwide. Importers are typically original equipment manufacturers (OEMs) for assembly, or distributors and service providers for aftermarket support. Exporters are often specialized component manufacturers or the engine manufacturers themselves. The trade in these parts is characterized by high-volume transactions for common components and specialized, lower-volume trade for proprietary or custom-engineered parts. Quality control, material specifications, and precise engineering are paramount, as these parts directly impact the performance and longevity of the complete engine or motor. Global supply chains for these components are complex, often involving multiple countries for sourcing raw materials, manufacturing, and final assembly.

Codes often confused with 8412.90
Common mistake. This code is often confused with general machinery parts under 8487 or parts of internal combustion engines under 8409, but it is specific to the non-electric engines of heading 8412. Care must be taken to ensure the part is exclusively for an engine of 8412.
Top exporters and importers of HS code 841290, 2025
In 2025, the largest exporter of HS code 841290 in UN Comtrade data was China, with 27% of world exports; the largest importer in UN Comtrade data was the United States, with 29% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
