Cold-Drawn 316 Stainless Steel Hydraulic Tube
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If heat-treated (normalized, annealed, or tempered)
Heat-finished seamless tubes of alloy steel fall under cold-formed but further processed category.
If welded rather than seamless
Welded tubes of stainless steel use Chapter 73 heading 7306, not seamless 7304.
If Specific end-use parts for engines/pumps classify under Chapter 84 by function.

Import Tips & Compliance
• 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)
