Double-Acting Hydraulic Cylinder for Excavators from China

This hydraulic cylinder converts hydraulic pressure into linear mechanical motion using a piston and rod in a double-acting configuration, designed specifically for heavy machinery like excavators. It falls under HTS 8412.21.0075 as a linear acting hydraulic power engine/motor, other than those for semiconductors or aircraft. Classified here due to its role in generating linear force in industrial equipment.

Import Tips

Verify cylinder bore diameter and stroke length against HTS subheading limits; exceeding certain sizes may require engineering samples for classification

Include detailed technical specs and end-use certification to avoid misclassification as aircraft parts under 8412.21.00.30

Ensure pressure ratings and material certifications (e.g

steel seals) comply with ASME standards to prevent customs holds
