Import Tips & Compliance
• Provide chiral purity documentation (e.g
• HPLC analysis) to confirm identity with named compound
• Register with EPA as technical grade active ingredient; retail formulations require separate approval
• Monitor for racemization during storage/transport which could trigger reclassification as mixture
