Import Tips

• Provide Certificate of Analysis (CoA) and pharmacopeial compliance (USP/EP) documentation to verify purity >99% and absence of pyrogens

• Ensure DEA/FDA registration for antibiotic imports; include stability data for transport conditions to prevent degradation

• Avoid misclassification as finished dosage forms—bulk powder only; common pitfall is missing batch-specific impurity profiles
