Low-Surface-Area Modified Graphite Spheres for Fast-Charging Anodes from Germany
Spherical graphite with proprietary silane surface treatment achieving <1.5 m²/g BET surface area for reduced SEI formation in fast-charging lithium batteries. Falls under HTS 3801.10.5010 as surface-modified artificial graphite powder. Treatment minimizes irreversible capacity loss during high-rate cycling.

Import Tips
• BET surface area test reports critical; values >3.0 m²/g may disqualify from 'surface-modified' specific subheading
• Declare LC50 data if silane treatment involves volatile organics to address potential hazmat classification
• Use incoterms clearly separating quality inspection from customs valuation to prevent disputes
