Last updated: July 2026 dataRotary-blade mowers — the dominant consumer and commercial lawn-care format — are classified here when the cutting device rotates in a horizontal plane, and the US schedule further subdivides them by power source and engine output: electric (including battery-operated) at 8433110010, and non-electric riding mowers in three engine-size bands (under 5.2 kW, 5.2–7.46 kW, and 7.46 kW and over) at 8433110020–8433110040. Vietnam leads US imports under this heading, reflecting major assembly operations there for global outdoor-power-equipment brands, with Mexico and China also prominent. The engine-kilowatt thresholds are a recurring classification issue, particularly as battery-electric models grow in market share.

The rated output of the engine in kilowatts at the time of importation governs placement into the under-5.2 kW (8433110020), 5.2–7.46 kW (8433110030), or 7.46 kW-and-over (8433110040) lines. Importers should obtain the manufacturer's rated power specification and retain it as supporting documentation for CBP review.
Robotic mowers with a horizontally rotating cutting blade are generally classifiable here under 8433110010 (electric lawn mowers, including battery-operated), provided their primary function is cutting grass on lawns, parks, or sports grounds. However, if a robotic unit incorporates significant autonomous-navigation electronics that could shift its essential character, a binding ruling from CBP is recommended before large-volume importation.
