Import Tips & Compliance
• Include isotopic enrichment certificate (typically >98% 13C); customs may require mass spec confirmation
• Declare as stable isotope, not radioactive, to avoid Chapter 28 nuclear materials scrutiny
• Small package sizes (grams) typical; bulk may trigger end-use verification for weapons research
