Last updated: July 2026 dataHydraulic and pneumatic cylinders and actuators — the linear and rotary motion elements of fluid power systems — are widely traded industrial components used in construction equipment, machine tools, aerospace ground support, and automation. NAICS 333995 covers both hydraulic (oil-based) and pneumatic (air-based) designs, a distinction that drives separate HTS subheading classification under chapter 84. Importers should be aware that certain hydraulic cylinders and actuators of Chinese origin carry Section 301 exposure, and that bore size, operating pressure rating, and stroke length are the specification details most likely to determine the correct tariff line.

The primary split in chapter 84 is between hydraulic cylinders (operating on liquid pressure) and pneumatic cylinders (operating on compressed air or gas). Operating medium, pressure rating, and whether the unit is linear or rotary are the key specification details customs authorities use to assign the correct subheading.
Certain fluid power cylinders and actuators originating in China are subject to Section 301 tariffs. The applicable measure depends on the specific HTS subheading, so importers should verify the correct classification and current Section 301 list status with a licensed customs broker before importing.
