Cold-Drawn 316 Stainless Steel Hypodermic Tubing
Seamless cold-drawn tubes of 316 alloy steel with circular cross-section, outer diameter under 16mm, used in medical needles and syringes. Classified under 7304.51.50.60 as cold-formed seamless hollow profiles of alloy steel, not further worked beyond cold-reduction. Meets chapter definition of 'wire' due to small cross-section.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cross-sectional dimension exceeds 16mm
Exceeds chapter wire definition, shifting to other bars/rods of alloy steel in Chapter 72.
If welded rather than seamless
Welded alloy steel tubes for machinery fall under Chapter 73 heading for welded pipes, not seamless.
If imported as finished hypodermic needle component
If specifically shaped for medical needles with end-use, classified as syringe/needle parts under medical instruments heading.

Import Tips & Compliance
• Obtain material test reports (MTRs) certifying alloy composition (e.g
• 316 stainless) and seamless production to avoid reclassification as welded
• For medical applications, ensure FDA compliance and provide end-use certificates; common pitfall is incorrect diameter measurement leading to 'wire' vs tube disputes
• Declare exact cold-forming process; cold-rolled finish must be documented to qualify under this subheading
