Surface-Modified Spherical Graphite Powder for Lithium-Ion Batteries
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not surface-modified or non-spherical
Standard artificial graphite powder without surface treatment or spherical morphology falls under the general 'other' subheading for artificial graphite.
If classified primarily as a battery anode material by end-use
Customs may reclassify highly processed graphite intended solely for battery anodes under carbides heading if it exceeds semi-manufactured graphite definitions.
If imported as pre-assembled anode mixture or electrode
When mixed with binders and solvents into slurry or formed into electrodes, it becomes a battery part under Chapter 85 rather than raw graphite.

Import Tips & Compliance
• 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
