Ti-6Al-4V Pre-Alloyed Sponge
Blended titanium sponge pre-alloyed with 6% aluminum and 4% vanadium for direct forging applications. Still classified under HTS 8108.20.0010 as unwrought titanium sponge since titanium exceeds 99% of metal content per Chapter notes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If melted and cast into billets before import
Any melting or casting beyond sponge form creates semi-finished articles under 8108.90.
If iron content exceeds other elements
High alloy steels with titanium as minor element use Chapter 72 classifications.
If aluminum predominates in the alloy matrix
Aluminum-based alloys shift to Chapter 76 per principal metal content rules.

Import Tips & Compliance
• Submit detailed alloy composition analysis proving titanium dominance to prevent Chapter 81 other metal alloy classification
• Blend homogeneity certification required; segregation leads to reclassification as mixture
• Special processing instructions for pre-alloyed sponge melting—declare to avoid parts misclassification
