Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2941.90Same rate: Free

If semi-synthetic derivative like gentamicin C with modified structure

Modifications beyond natural fermentation products shift to 'other' antibiotics per chapter classification rules.

3003.39Higher: 10% vs Free

If put up in bulk packs over 125g for medicinal use

Bulk medicaments (not retail-packed) fall under Chapter 30 per HTS structure, excluding Chapter 29 APIs.

2936.29Higher: 10% vs Free

If classified primarily by vitamin B structure rather than antibiotic function

Chapter notes require classification in last occurring heading; some aminoglycosides could overlap with nitrile/nitrile-oxide functions.

Import Tips & Compliance

Provide microbial origin documentation and HPLC chromatograms showing C1, C1a, C2, C2a components typical of natural gentamicin

Comply with FDA bioequivalence standards if referencing ANDAs; declare exact sulfate content

Watch for misdeclaration as veterinary grade, which may trigger different residue testing requirements
