Cold-Drawn 316 Stainless Steel Hydraulic Tube from China

Seamless cold-drawn tube made from 316 alloy steel with circular cross-section, used in high-pressure hydraulic systems for machinery. It falls under HTS 7304.51.50 as a cold-formed hollow profile of other alloy steel, not further worked beyond cold-rolling. Dimensions typically under 16mm wall thickness to qualify as precise tubing.

Import Tips

Verify alloy steel composition via mill test certificate (MTC) to confirm 'other alloy steel' status exceeding 1.5% alloy content

Ensure documentation proves cold-drawn process; heat treatment may shift to 7304.41 if normalized or annealed

Measure wall thickness; if exceeding structural limits, it may classify under tubes for boilers (7304.39)
