Pitch-Coated Spherical Graphite for Anode Materials from Mexico
Spherical artificial graphite particles coated with petroleum pitch to improve coating uniformity and capacity retention in EV battery anodes. Classified under HTS 3801.10.5010 due to its surface modification and semi-manufactured state for further electrode processing. The coating prevents direct electrolyte contact and enhances electrochemical performance.

Import Tips
• Provide FTIR or XPS analysis proving pitch surface coating to justify surface-modified classification under 3801.10.5010
• Include tap density (≥1.0 g/cm³) and SSA (<2.0 m²/g) specs in documentation, as these define battery-grade quality
• Package in nitrogen-flushed bags to prevent oxidation; improper storage can lead to quality rejection at entry
