Import Tips
• Provide SEM analysis confirming diamond structure and synthetic origin to distinguish from carbon nanomaterials
• Ship in inert atmosphere packaging to prevent oxidation; declare protective gas if applicable
• Document end-use as coating precursor to avoid 7113 classification as goldsmiths' wares
