Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formed into tubes, pipes, or profiles
Any worked shapes beyond sponge form become articles thereof under 8108.90, no longer unwrought.
If for sponge with higher impurity levels not meeting base metal definition
Lower purity sponge may classify as powders if not predominantly titanium per Chapter 81 alloy notes.
If ferro-titanium sponge with significant iron content
Ferro-titanium alloys exceeding iron thresholds fall under Chapter 72 iron/steel headings.

Import Tips & Compliance
• Obtain supplier's chemical analysis certificate specifying max 0.20% oxygen for aerospace grades to support classification
• Declare vacuum-packed sponge to prevent oxidation; watch for reclassification if contaminated during transit
