Surface-Modified Spherical Graphite Powder for Lithium-Ion Batteries from Germany

This is high-purity artificial graphite processed into spherical particles with surface modification to enhance electrolyte compatibility and SEI layer formation in lithium-ion battery anodes. It falls under HTS 3801.10.5010 as 'surface-modified spherical graphite,' a semi-manufactured form of artificial graphite optimized for battery applications. The spherical morphology and surface treatment distinguish it from standard graphite powders.

Import Tips

Obtain certificates of analysis confirming particle size (typically 10-20 microns), sphericity (>95%), and surface treatment (e.g

pitch coating) to match HTS 3801.10.5010 criteria

Verify supplier's REACH or TSCA compliance for chemical substances; battery-grade graphite often requires EPA pre-manufacture notices

Avoid misclassification as battery components (HTS 85xx); declare as semi-manufactured graphite to prevent duty reassessment
