2941.90.10.50 - Other 🖩

This HTS category, 2941.90.10.50, encompasses "Other" antibiotics not specifically enumerated in preceding subheadings. It serves as a residual classification for antibiotic substances that do not fall within the defined categories of specific antibiotic classes, such as aminoglycosides. This includes a wide array of naturally derived or synthesized antibiotic compounds that exhibit antimicrobial properties but are not explicitly listed elsewhere within the 2941 heading.

The key distinction of this category from its sibling, 2941.90.10.10 (Aminoglycoside antibiotics), lies in the structural and chemical characteristics of the antibiotic. Aminoglycosides are defined by their specific chemical structure containing amino sugars linked by glycosidic bonds. This category, conversely, is for antibiotics that do not possess this defining structural feature. Therefore, classification hinges on whether an antibiotic's chemical composition aligns with the definition of an aminoglycoside or if it falls into a distinct, unclassified group.

As a leaf node, 2941.90.10.50 has no further subcategories. When classifying goods under this heading, it is crucial to exhaust all other more specific antibiotic classifications within 2941. If an antibiotic substance does not fit the criteria for any other enumerated antibiotic type, and is indeed an antibiotic with demonstrated antimicrobial activity, it would then be classified here under "Other." This necessitates a thorough review of the substance's chemical identity and its known pharmacological activity to confirm it is not otherwise classified.
