Pitch-Coated Spherical Graphite for Anode Materials
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pitch coating dominates the product's value/composition
Petroleum pitch preparations may shift to Chapter 27 if the graphite serves merely as a carrier for the pitch coating.
If supplied as ready-to-use anode active material premix
Chemical preparations containing graphite for specific industrial uses (like battery slurries) can fall under prepared binders heading.
If colloidal graphite paste form rather than powder
If dispersed in liquid medium for paste application, it becomes colloidal graphite under the adjacent subheading.

Import Tips & Compliance
• 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
