Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in granular or powder form smaller than sponge chunks
Titanium powders and granules fall under waste and scrap provisions rather than sponge, changing the heading within Chapter 81.
If classified as titanium powders rather than sponge
Fine titanium powders are separately provided for in the powders subheading, distinguished by particle size and production method.
If containing less than 99% titanium with significant impurities
Slag and ash containing titanium, not meeting unwrought metal purity, shifts to Chapter 26 for mineral products.

Import Tips & Compliance
• Verify sponge purity certification (e.g
• ASTM B299) and provide mill test reports to confirm unwrought status and avoid misclassification as waste
• Ensure proper hazardous material declarations if sponge contains residual magnesium or chloride from Kroll process production
• Use NA form for defense-related imports; common pitfall is incorrect valuation excluding processing loss allowances
