2941.20 - Streptomycins and their derivatives; salts thereof:

This HTS category, 2941.20, specifically covers streptomycins and their derivatives, along with any salts thereof. Streptomycins are a group of antibiotics, most notably streptomycin itself, known for their effectiveness against various bacterial infections. This heading focuses on the chemical compounds and their related forms rather than finished pharmaceutical preparations, which would be classified elsewhere.

Distinguishing 2941.20 from its siblings is crucial for accurate classification. While other headings within 2941.10, 2941.30, 2941.40, and 2941.50 cover distinct classes of antibiotics such as penicillins, tetracyclines, chloramphenicol, and erythromycin, this section is dedicated solely to the streptomycin family of compounds. The classification is based on the specific chemical structure and origin of these antibiotics.

Within this category, two subcategories exist to further refine the classification of streptomycins. 2941.20.10.00 specifically identifies dihydrostreptomycin and its derivatives, a closely related but chemically distinct compound from streptomycin. The residual subcategory, 2941.20.50.00, serves as a catch-all for any other streptomycins or their derivatives not otherwise specified, ensuring comprehensive coverage of this antibiotic group.
