High-Capacity Spherical Graphite with Doped Surface Layer from Canada
Artificial graphite spheres surface-doped with nitrogen or boron compounds to boost reversible capacity above 360 mAh/g for high-energy-density batteries. HTS 3801.10.5010 applies as surface-modified artificial graphite in powder form for semi-manufactured battery production. Doping alters surface chemistry without changing bulk structure.

Import Tips
• Submit elemental analysis (ICP-MS) confirming dopant levels (0.1-1 wt%) to prove surface modification qualifies for this specific HTS
• Battery passport or material data sheets required for traceability under emerging US battery regulations
