Alloy Steel Hydraulic Cylinder Tube from Japan
Seamless tube made of alloy steel, such as 4140 grade, with wall thickness under 4 mm, used in manufacturing hydraulic and pneumatic cylinders. It falls under HTS 7304.90.70.00 as a seamless hollow profile of alloy steel with thin walls. These tubes are precision-honed inside for piston rod sealing.

Import Tips
• Verify alloy steel composition via mill test certificate (MTC) to confirm classification under 7304, avoiding reclassification to carbon steel headings
• Ensure wall thickness documentation <4 mm; ultrasound gauging reports prevent disputes at customs
