Silicon-Graphite Composite Anode Paste from Canada
A semi-manufactured paste composed of artificial graphite and silicon nanoparticles designed as active anode material for lithium-ion batteries. It falls under HTS 3801.90.00.10 due to its graphite base with silicon content in paste form, used in battery electrode production. This classification applies to preparations based on graphite containing silicon for anode applications.

Import Tips
• Verify silicon content via lab analysis to confirm classification under 3801.90.00.10; misclassification as pure graphite risks penalties
• Include detailed chemical composition and battery end-use declarations in import documentation for CBP review
• Ensure MSDS sheets accompany shipments due to handling hazards of fine graphite-silicon powders
