Synthetic Spherical Graphite with Carbon Nanotube Surface Modification from Germany
Artificial graphite spheres partially covered with vapor-deposited carbon nanotubes for improved electrical conductivity in battery anodes. HTS 3801.10.5010 covers this surface-modified form of artificial graphite used in semi-manufactured state. CNT layer enhances rate capability without altering core graphite structure.

Import Tips
• TEM cross-section images required to prove surface-only CNT modification vs. bulk composite
• Carbon content analysis must show >95% graphite to avoid reclassification as polymer composite
• Nanomaterial reporting under TSCA may apply; check supplier's SNUR status
