Unwrought Titanium and Titanium Powders

Titanium sponge (8108200010) is the primary reduced form produced by the Kroll process — a porous, irregular mass that has not been melted into a consolidated shape. Ingots (8108200030) are sponge or scrap that has been vacuum-arc or electron-beam melted into a solid cylindrical form ready for further working. Both are 'unwrought,' but they classify under separate 10-digit lines, so the production stage documented on the mill certificate determines the correct entry.

For titanium destined for aerospace or defense applications, importers and downstream processors typically require a certified mill test report (CMTR) confirming chemical composition and compliance with applicable ASTM or AMS specifications. Additionally, given evolving US policy on critical-mineral supply chains, maintaining clear records of country of origin, smelter identity, and processing history is advisable to support any future regulatory or customer due-diligence requirements.
