Import Tips
• Provide pharmacopeia certificates and isomer-specific HPLC chromatograms for CBP verification
• Declare as UN1129 PG II with child-resistant packaging if for pharma end-use to meet FDA import alerts
• Monitor REACH/ TSCA registration; failure to pre-register triggers FDA holds on pharma intermediates
