Import Tips
• Submit particle size distribution reports to CBP to confirm pure compound status vs. nanomaterial preparations
• Comply with EPA nanomaterial reporting under TSCA for imports exceeding certain volumes
• Package in inert atmospheres if sensitive; document to avoid reclassification as unstable reactive under hazmat rules
