3801.10.50.10/Surface-Modified Spherical Graphite Powder for Lithium-Ion Batteries/China

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

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
