Product classification

HS code for Hydraulic motor parts: 8412.90

Engines, parts, for engines and motors of heading no. 8412.

Classification of hydraulic motor parts under HS 8412.90

Parts for hydraulic motors are classified under HS code 841290. This classification is governed by Note 2 to Section XVI of the Harmonized System, which dictates that parts suitable for use solely or principally with a particular kind of machine are to be classified with those machines, or in this case, in the specific 'parts' subheading of the same heading. Since hydraulic motors fall under heading 8412, their identifiable components are directed to 841290. To qualify for this code, the item must be a dedicated component that lacks independent functionality and is not specifically mentioned elsewhere in the nomenclature. This includes structural and internal components that are essential for the motor's operation. It is important to note that general-purpose parts, such as standard bolts, washers, or O-rings, are excluded from this code and are classified according to their constituent material or their own specific headings.

Codes often confused with 8412.90

Common mistake. The most common misclassification occurs with parts for hydraulic pumps, which belong under 841391. Because many components are interchangeable between pumps and motors, the 'principal use' rule must be applied. Furthermore, seals and gaskets are often incorrectly placed here; they must be classified under 4016 (rubber) or 3926 (plastics) unless they are part of a specialized kit. Bearings are also excluded and fall under heading 8482.

Top exporters and importers of HS 841290 (the code used for hydraulic motor parts), 2025

In 2025, the largest exporter of HS 841290 (the code used for hydraulic motor parts) 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).

How do I classify Hydraulic motor parts for customs?

Hydraulic motor parts is classified under HS code 841290 — Engines; parts, for engines and motors of heading no. 8412. This is a 6-digit subheading level code.

Are hydraulic seals classified under 841290?

No, seals and gaskets are generally classified by their material (e.g., 4016 for rubber) rather than as machinery parts, unless they are part of a specific assembly.

Which countries are the top exporters of hydraulic motor parts (HS 841290)?

In 2025, the top exporters of HS 841290 (the code used for hydraulic motor parts) in UN Comtrade data were China ($2.8B, 27% of world exports), Denmark ($1.2B) and the United States ($1.2B). World exports came to about $10.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).
