U.S. imports of hydraulic power engines and motors, linear acting (cylinders) (HS 841221) totaled $133.9M in July 2026, traded with 58 countries.
Importers of Hydraulic Power Engines and Motors, Linear Acting (Cylinders) paid $26.3M in duties in July 2026 — an effective duty rate of 25% on $104.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataLinear-acting hydraulic cylinders convert fluid pressure into straight-line mechanical force and are foundational components in construction equipment, agricultural machinery, industrial presses, and aerospace actuation systems. The US schedule subdivides this heading by cylinder design: tie-rod (8412210015), welded-flange (8412210030), telescoping (8412210045), rodless (8412210060), and a residual line (8412210075) — distinctions that reflect the wide range of stroke, pressure, and mounting configurations used across industries. Canada leads US imports, with the United Kingdom and Germany also significant sources. Importers should note that hydraulic cylinders integrated into complete machines may be classifiable with the machine rather than separately under this heading.

Under GRI 2(a) and the machinery chapters' component rules, a hydraulic cylinder imported as a separate article is classified under 841221. However, if it is imported as part of an incomplete or unassembled machine, or if it is a dedicated component presented with its host machine, it may be classified with that machine under the relevant heading. The key factors are whether the cylinder is imported separately and whether it has independent commercial use beyond a single machine application.
Tie-rod cylinders (8412210015) use external rods to hold end caps under pressure and are common in industrial and mobile equipment applications. Welded-flange cylinders (8412210030) have end caps welded or flanged directly to the barrel, offering a more compact profile suited to higher-pressure or space-constrained applications. The construction method is the controlling classification criterion, so importers should obtain manufacturer specifications confirming the cylinder body construction type.
