Import Tips
• Classify based on graphite content (>50%) with silicon; test viscosity to confirm paste vs. liquid chemical status
• Ship in temperature-controlled containers to maintain slurry stability; declare shelf life on commercial invoice
• EPA may require pre-import notice for new chemical substances if silicon particle morphology differs
