Import Tips
• Classify activity level (typically low for ThO2); use UN 2972 for transport if above exempt limits
• Provide certificates of analysis confirming thorium content and purity to meet 'chemically defined' criteria
• Avoid misclassification as ceramic powder (6903); specify chemical compound status in entry docs
