Import Tips
• Include purity certificates (ICP analysis) and flake morphology reports for high-value electronics grade material
• Specify end-use as 'EMI shielding compound ingredient' to avoid electrical parts classification
• Declare RoHS compliance documentation for electronics import facilitation
