Cold-Drawn Alloy Steel Hydraulic Cylinder Tube
Cold-drawn welded tube from 4140 alloy steel, 3-inch OD with 3 mm wall thickness, precision-finished for hydraulic cylinder liners in heavy machinery. Classified under HTS 7306.50.50.30 due to its welded construction, circular cross section, cold-reduction process, and alloy steel material with sufficient wall thickness. Ideal for high-pressure fluid transfer.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hot-rolled rather than cold-reduced
Hot-rolled versions lack the cold-drawing process, falling under a different subheading with potentially lower precision specs.
If imported as part of a complete hydraulic cylinder
When assembled into machinery parts, it may classify under hydraulic system components rather than raw tube.
If non-circular cross section
Square or rectangular profiles shift to 7306.60, separate from circular tubes.

Import Tips & Compliance
• Provide mill test reports confirming cold-reduction and alloy composition; label as 'other alloy steel' to distinguish from stainless; ensure no fittings attached to avoid set classification
