Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified by heterocyclic ring structure alone
Beta-lactam ring focus might suggest azetidine classification, but specific penicillin structure prevails per chapter notes.
If for veterinary immediate use
Antibiotics for animal therapy in dosage form shift to immunological/veterinary products.
If US goods returned after processing
Articles assembled abroad from US components qualify for duty-free entry under special provisions.
