Titanium Sponge
Titanium sponge is a porous form of unwrought titanium produced by the Kroll process, used as the primary intermediate material for manufacturing titanium mill products like ingots and billets. It falls under HTS 8108.20.00.95 as 'other' unwrought titanium, excluding powders, and is not in a form like bars, rods, or profiles. This classification applies to bulk sponge material imported for further processing in aerospace and medical industries.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing significant impurities or residues from production
Waste and scrap titanium falls under 8108.30, distinguished from high-purity unwrought sponge by usability and cleanliness standards.
If processed into powders
Titanium powders are classified separately under 'other articles' in 8108.90, based on particle form rather than unwrought bulk.
If in granular form exceeding powder specifications
Granules have a specific subheading 8108.20.00.30 within unwrought, separated from 'other' sponge by size and shape criteria.

Import Tips & Compliance
• Verify purity and composition certificates to confirm it meets unwrought titanium definitions and avoids misclassification as alloys under Chapter 81
• Include material test reports (MTRs) and origin documentation, as titanium sponge often requires aerospace-grade traceability
• Avoid common pitfalls like declaring as scrap (8108.30); ensure it's free of excessive impurities
Related Products under HTS 8108.20.00.95
Titanium Powder (Coarse)
Coarse titanium powder consists of unwrought titanium particles larger than standard fine powder, used in additive manufacturing and powder metallurgy. Classified under HTS 8108.20.00.95 as 'other' unwrought titanium, it distinguishes from finer powders or wrought forms by its bulk, non-profiled state. Ideal for 3D printing aerospace components.
Titanium Aerogel
Titanium aerogel is an ultra-lightweight, porous unwrought titanium material produced via supercritical drying, retaining high surface area for catalysis and insulation. It qualifies under HTS 8108.20.00.95 as 'other' unwrought titanium, not powders or profiles, due to its bulk aerated structure. Used in advanced thermal barriers for space applications.
Titanium Dendritic Crystals
Titanium dendritic crystals are branched, unwrought structures grown via vapor deposition, used as precursors for high-purity alloys. Classified in HTS 8108.20.00.95 as 'other' unwrought titanium, distinct from powders by crystalline bulk form. Applied in semiconductor and nuclear reactor components.
Beta Titanium Billets (Unwrought)
Beta titanium billets are stabilized alloy unwrought forms (e.g., Ti-3Al-8V-6Cr-4Mo-4Zr) cast but not hot-worked, for aerospace forgings. HTS 8108.20.00.95 as pure titanium equivalent if <99% but dominant base per notes. Distinguishes from wrought bars.
Titanium Shot
Titanium shot consists of small spherical unwrought particles for peening and blasting, not fine enough for powder metallurgy. Classified HTS 8108.20.00.95 'other' unwrought titanium. Enhances fatigue life in turbine blades.
Amorphous Titanium Ribbon
Amorphous titanium ribbon is rapidly quenched unwrought foil-like strip, metastable for magnetic applications. HTS 8108.20.00.95 as 'other' unwrought, pre-wrought. Used in thin-film deposition.
