Yes. FDA prohibits the use of chloramphenicol in food-producing animals in the United States, and imported shipments intended for such use would be refused entry. Importers must clearly document the intended end-use (e.g., human pharmaceutical, veterinary companion animal, or research) to avoid admissibility issues at the port of entry.

European suppliers such as those in Spain and Hungary typically produce chloramphenicol to stringent EU GMP standards, which may be required for finished-dosage-form manufacturers seeking dual regulatory compliance. Asian-sourced material from China and India is often more cost-competitive for bulk or research-grade applications, but buyers should verify FDA facility registration status before importing.
