317 Stainless Steel Hypodermic Tubing
Precision-welded thin-wall tubing made from 317 stainless steel, containing 2-3% molybdenum and over 11% nickel, with wall thickness under 1.65 mm and circular cross-section. Used in medical devices for its corrosion resistance in harsh environments. Falls under 7306.40.1010 due to its welded construction, specific alloy composition, and dimensions.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If seamless rather than welded
Seamless stainless steel tubes of circular cross-section fall under Chapter 73 heading 7304, regardless of wall thickness.
If wall thickness 1.65 mm or greater
Thicker-walled welded stainless tubes shift to subheading 7306.40.50, changing duty rates.
If made from stainless bar stock exceeding 16 mm width
Products from wider stock may classify as bars under Chapter 72 rather than tubes.

Import Tips & Compliance
• Verify alloy certification with mill test reports showing exact Mo (1.5-5%) and Ni (>0.5%) content to avoid reclassification
• Ensure wall thickness documentation under 1.65 mm; common pitfall is mismeasurement leading to higher tariff bins
• For medical use, prepare FDA import alerts and biocompatibility docs alongside HTS paperwork
