Import Tips
• Secure DEA import permit if Schedule I controlled precursor; declare via ACE with chemical abstract number 151-50-8
• Comply with OSHA 1910.1000 cyanide exposure limits; pitfall is ignoring state-level toxics use reduction laws
• Bonded warehouse storage recommended for hazmat; ensure spill containment exceeds 110% container capacity
