Import Tips

• Verify graphite content exceeds 50% by weight and ensure supplier provides chemical composition certificate for CBP classification

• Include safety data sheets (SDS) documenting non-hazardous status; common pitfall is misclassification as carbon electrodes under 8545

• Label packages with UN number if pitch content requires it; obtain prior notice via ACE system for bulk shipments
