Import Tips & Compliance
• Include ammonium content verification in CoA, as per note on ammonium salts in headings 2826-2842
• Adhere to OSHA PEL limits in import declarations; common error is incomplete MSDS leading to holds
• Store in cool, dry conditions pre-clearance to prevent decomposition affecting purity tests
