Products classified under HTS 7608.20.00.30
Seamless Aluminum Alloy Hydraulic Cylinder Tube
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.
6063-T6 Seamless Aluminum Alloy Round Tube
A seamless extruded tube from 6063-T6 aluminum alloy commonly used in architectural frameworks and structural applications. Classified under HTS 7608.20.00.30 as it is of aluminum alloys (Mg-Si alloyed) and seamless, distinguishing it from welded tubes. The T6 temper provides excellent strength-to-weight ratio for load-bearing uses.
Seamless 7075 Aluminum Alloy Aircraft Tubing
High-strength seamless tubing from 7075 aluminum alloy (Zn-Cu-Mg) used in aerospace fuel lines and structural members. It qualifies for HTS 7608.20.00.30 as seamless aluminum alloy tubes where alloying elements like zinc exceed 1% total. Precision tolerances ensure compliance with aviation standards.
Seamless Aluminum Alloy Heat Exchanger Tubing
