Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hafnium 1:500 or higher
Higher hafnium zirconium scrap uses separate subheading 8109.29.
If titanium-zirconium alloy scrap
Alloys with dominant titanium shift to Chapter 81 titanium headings.

Import Tips & Compliance
• Use ITAR export controls if US-origin due to aerospace sensitivity
• Batch by alloy grade to simplify customs valuation
