2941.90.50.00 - Other

This classification, HTS Code 2941.90.50.00, encompasses antibiotics that do not fall under the specific subheadings for aromatic or modified aromatic structures. It serves as a residual category for antibiotics that are structurally distinct from those primarily characterized by aromatic rings or modifications thereof. The scope includes a wide range of antibiotics, provided they exhibit antibiotic properties and are not otherwise classified.

This category is distinguished from its sibling, 2941.90.30.00, by the absence of aromatic or modified aromatic features as the primary defining characteristic of the antibiotic molecule. While a compound classified under 2941.90.30.00 would contain such ring structures, the antibiotics covered here are typically derived from different chemical frameworks, such as aliphatic chains or other non-aromatic cyclic systems. The focus for classification within this subheading is on the presence of antibiotic activity coupled with a lack of aromaticity in the core structure.

As this is a leaf node, there are no further subcategories. Therefore, classification into 2941.90.50.00 relies on the precise determination of whether a product exhibits antibiotic properties and does not meet the criteria for other more specifically defined antibiotic classifications within heading 2941, particularly those that are aromatic or modified aromatic.
