Import Tips
• Declare exact CAS number (430-64-8) and concentration; impurities may trigger reclassification under Chapter notes
• Obtain prior DEA/CWC approvals; Schedule 2 chemical requiring end-user certificates for import
• Use fluoropolymer-lined containers to prevent hydrolysis during shipping, common pitfall leading to customs holds
