Seamless Aluminum Alloy Hydraulic Cylinder Tube from China

This seamless tube made from 6061 aluminum alloy is designed for use in hydraulic and pneumatic cylinders in industrial machinery. It falls under HTS 7608.20.00.30 because it is a tube of aluminum alloy produced without seams, meeting the definition where aluminum predominates but alloy elements exceed non-alloyed limits. The smooth interior finish ensures low friction for piston movement.

Import Tips

Verify alloy composition certification to confirm it meets aluminum alloy criteria (aluminum >50% with other elements >1%); obtain mill test reports for seamless production proof; watch for anti-dumping duties on certain Chinese-origin tubes
