Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as titanium granules for powder metallurgy
Granular titanium used in medical powder injection molding classifies as waste/scrap, not sponge.
If already formed into orthopedic implant components
Finished medical appliance parts shift to Chapter 90 regardless of titanium composition.
If for sponge processed into unwrought shapes like slabs
Any surface working beyond sponge texture makes it other unwrought articles.

Import Tips & Compliance
• Include biocompatibility test results and purity certificates; FDA registration may be required for medical device manufacturers
• Package in inert atmosphere to maintain low bioburden; mislabeling as industrial grade triggers reclassification
• Avoid classifying consolidated sponge (EBM-formed) under this code—use parts headings instead
