Import Tips
• Submit assay reports showing nitrosylsulfate content > specific threshold to confirm sulfonitric classification over plain nitric acid
• Use UN 1791 classification for transport; ensure tanks are acid-resistant and include emergency response plans
• Avoid misdeclaration as 'mixed acid' which could trigger 3824 reclassification; maintain 99%+ purity records
