Titanium Sponge Ingots
Titanium sponge ingots are porous, unwrought blocks produced by reducing titanium tetrachloride, serving as intermediate forms for further processing into titanium alloys. Classified under HTS 8108.20.0030 as unwrought titanium ingots, excluding powders, they are essential raw material in aerospace and medical industries. Their high purity and reactivity necessitate careful handling during import.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing more than 15% impurities or production rejects
Waste and scrap titanium falls under 8108.30, distinguished from high-purity unwrought ingots by lower quality and irregular form.
If processed into bars, rods, or profiles
Semi-finished products like bars exceed 'unwrought' definition, moving to 8108.90 for wrought articles.
If in powdered form rather than ingot
Titanium powders are classified in Chapter 28 as carbides or chemical compounds, not under unwrought metals in Chapter 81.

Import Tips & Compliance
• Verify purity and composition certificates to confirm unwrought status and avoid reclassification as waste/scrap under 8108.30
• Provide mill test reports (MTRs) documenting chemical analysis, as titanium ingots must meet ASTM standards for Chapter 81
• Ensure proper packaging to prevent oxidation; declare exact weight and alloy content to prevent undervaluation penalties

Titanium Alloy Ingots Grade 5
Grade 5 titanium alloy ingots (Ti-6Al-4V) are unwrought titanium blocks containing 6% aluminum and 4% vanadium, melted via vacuum arc remelting for high-strength applications. They fall under HTS 8108.20.0030 as unwrought titanium ingots, provided the titanium content dominates over other elements. Widely used in aircraft engines and implants due to superior strength-to-weight ratio.
Commercially Pure Titanium Ingots CP-2
CP-2 commercially pure titanium ingots are unwrought forms with minimal interstitial impurities, produced by electron beam melting for corrosion-resistant uses. Under HTS 8108.20.0030, they qualify as unwrought ingots due to their cast, unworked state and titanium-dominant composition. Common in chemical processing equipment and marine hardware.
Titanium EBCH Ingots
Electron Beam Cold Hearth Melted (EBCH) titanium ingots are high-purity unwrought blocks refined to remove high-density inclusions for critical aerospace parts. Classified in HTS 8108.20.0030 as unwrought titanium ingots, their production process ensures uniformity without working. Ideal for rotating components like turbine blades.
Titanium Vacuum Arc Remelt Ingots
VAR titanium ingots undergo vacuum arc remelting to achieve ultra-clean, unwrought form for biomedical and defense applications. HTS 8108.20.0030 covers these as unwrought ingots, unworked beyond melting and casting. Their defect-free structure supports high-performance implants and missiles.
