Import Tips
• Provide chiral purity documentation (e.g
• >99% ee) and stereoisomer identification to confirm HTS specificity
• Comply with Controlled Substances Act import permits; declare as 'bulk drug substance' on CBP forms
• Use child-resistant packaging if retail-distributed, though bulk chemical imports typically require industrial labeling
