Import Tips
• Require NIST-traceable certificates of analysis specifying ACS compliance and Lot# traceability
• Ship in amber glass bottles ≤1L with child-resistant caps for lab quantities to meet hazmat exemptions
• Declare exact CAS# 78-84-2; misdeclaration risks penalty and reclassification to generic mixtures
