U.S. imports of hydraulic power engines and motors, other than linear acting (HS 841229) totaled $92.0M in August 2026, imported from 62 countries.
Importers of Hydraulic Power Engines and Motors, Other Than Linear Acting paid $16.8M in duties in August 2026, an effective tariff rate of 18.30% of the $92.0M imported — duty actually collected as a share of that value, not the published tariff schedule. Hydraulic Power Engines and Motors, Other Than Linear Acting imports of $92.0M in August 2026 ran 20% above the year-to-date monthly average of $76.5M.
Last updated: August 2026 dataRotary and oscillating hydraulic motors — including gear-type, radial-piston, and axial-piston designs — provide continuous or limited-rotation mechanical output for mobile machinery, industrial drives, and marine propulsion. The US schedule breaks out hydrojet engines for marine propulsion (8412294000) as a distinct line, then subdivides unlimited-rotary hydraulic engines by internal design: gear (8412298015), radial-piston (8412298030), axial-piston (8412298045), and other rotary (8412298060), with a residual line (8412298075) for remaining types. Japan leads US imports under this heading, reflecting the strong position of Japanese hydraulic equipment manufacturers in the global market, with Germany and the United Kingdom also significant sources. The internal design type — gear, radial-piston, or axial-piston — is the primary classification determinant and should be confirmed from manufacturer technical data.

Hydrojet engines (8412294000) are specifically designed to propel watercraft by expelling a high-velocity water jet, using hydraulic principles in a marine propulsion context. Other rotary hydraulic motors that happen to be used in marine applications but do not function as jet propulsion units would fall to the appropriate rotary-acting lines based on their internal design. The intended propulsion function — not merely marine use — is the distinguishing criterion.
Manufacturer technical datasheets, engineering drawings, or product catalogs that identify the internal mechanism (gear, radial-piston, or axial-piston) are the most reliable supporting documents. CBP may request this information during a CF-28 inquiry, and without it, the importer may be unable to defend classification in the more specific lines versus the residual 8412298075 line.
