Import Tips
• Obtain Certificates of Analysis (COA) proving ammonia content to avoid disputes over 'aqueous solution' purity
• Comply with EPA regulations for hazardous substances; declare as corrosive material on customs entry
• Use UN-approved containers; common pitfall is insufficient spill containment labeling leading to delays
