Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as other penicillins with penicillanic acid structure
Ampicillin derivatives not specifically named as ampicillin fall under the residual penicillin subcategory.
If imported as finished capsules or tablets
Bulk chemical compounds become medicaments in dosage form, moving to Chapter 30 for human medicinal use.
If containing mixtures of multiple antibiotics
Other antibiotics not purely ampicillin are classified in the broader antibiotics heading.
