Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If misclassified as chloride salt alone
Organic pharmaceutical salts follow antibiotic parent per note 5(C)(1), not inorganic chlorides.
If pre-mixed ophthalmic solutions
Bulk salts stay Chapter 29; formulated eye drops become Chapter 33 beauty preparations if >10% concentration.
If veterinary impurities exceed pharma specs
Purer pharma salts in specific 2941.40; veterinary in other antibiotics per purity notes.

Import Tips & Compliance
β’ Validate HCl content (typically 18-21%); excess free acid causes eye irritation compliance issues
β’ Use amber packaging for light-sensitive imports; UV degradation affects potency declarations
β’ Distinguish research vs GMP grades; non-GMP may face FDA detention without end-use certificates
