Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If veterinary grade with impurities exceeding 1%
Other antibiotics not elsewhere specified; purer forms stay in specific chloramphenicol heading per chapter note 3.
If pre-formulated as injectable suspension for retail
Bulk API becomes medicaments in dosage form; chapter exclusions direct to Chapter 30 for finished drugs.
If dissolved in solvent for transport exceeding safety put-up limits
Chapter note (e) excludes solutions not solely for safety/transport if solvent alters use suitability.

Import Tips & Compliance
• Require Certificate of Analysis (CoA) confirming purity >99% and identity via HPLC to meet FDA import standards for bulk APIs
• Ensure DEA compliance if any precursor status applies; chloramphenicol has veterinary restrictions in some markets
• Label as 'For Pharmaceutical Use Only - Not for Human Consumption' to avoid retail drug classification pitfalls
