HS Code 8412.21 – Engines; hydraulic power engines and motors, linear acting (cylinders)
HS code 8412.21 is the 6-digit subheading for engines, hydraulic power engines and motors, linear acting (cylinders). It is used for single-acting hydraulic cylinders, double-acting hydraulic cylinders, telescopic hydraulic cylinders, tie-rod hydraulic cylinders and welded hydraulic cylinders.
What HS 8412.21 covers
This HS code covers hydraulic cylinders, which are linear actuators that convert hydraulic fluid power into linear mechanical force and motion. These essential components are ubiquitous in industrial machinery, construction equipment, agricultural vehicles, and various mobile applications, providing robust and precise linear movement. International trade is driven by the global manufacturing sector's demand for reliable and powerful linear motion control. Importers include manufacturers of heavy equipment, industrial automation integrators, and MRO suppliers for machinery across diverse industries. Exporters are specialized hydraulic component manufacturers. The market is characterized by a wide range of standard and custom-engineered cylinders, with trade volumes reflecting global industrial production levels, infrastructure development, and agricultural mechanization trends worldwide.

Codes often confused with 8412.21
Common mistake. This code might be confused with 841229 (other hydraulic power engines/motors) if the linear acting characteristic is overlooked, or with 8479 (machines having individual functions) if the cylinder is part of a larger, more complex machine.
Top exporters and importers of HS code 841221, 2025
In 2025, the largest exporter of HS code 841221 in UN Comtrade data was the United States, with 17% of world exports; the largest importer in UN Comtrade data was the United States, with 18% 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).
