Welded Alloy Steel Hydraulic Tubing 12mm OD
This is a welded tube of circular cross section made from alloy steel, with an outer diameter of 12mm and wall thickness of 1.2mm, used in hydraulic systems for fluid transfer. It falls under HTS 7306.50.10.00 because it is welded, of alloy steel, circular, and has a wall thickness less than 1.65mm. The thin wall allows for lightweight construction while maintaining pressure resistance.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If seamless rather than welded
Seamless tubes of alloy steel fall under Chapter 73 heading 7304, regardless of wall thickness.
If made of stainless steel
Stainless steel variants are classified separately under 7306.30, even if welded and thin-walled.
If imported as part of a finished pump
If assembled into a pump housing, it may be classified by end-use under pump parts in 8413.

Import Tips & Compliance
• Verify alloy steel composition meets ASTM standards like A213 for proper classification and provide mill test certificates
• Ensure wall thickness documentation is precise, as exceeding 1.65mm shifts to 7306.50.50.00
• Label as 'welded' to avoid misclassification as seamless under 7304
