Harmonized System Code Classification

HS Code: 2941903000
Description: Antibiotics: Other: Other: Aromatic or modified aromatic

Classification Details:
- HS Code 29: Organic Chemicals
- HS Code 2941: Antibiotics
- HS Code 294190: Other antibiotics
- HS Code 29419030: Aromatic or modified aromatic antibiotics

Explanation:
This HS code is used for antibiotics that are aromatic or modified aromatic in nature. These types of antibiotics typically have a benzene ring or similar aromatic structure, which plays a key role in their biological activity. They may include compounds like sulfonamides or other synthetic derivatives with modified aromatic rings.

Examples of Products:
- Sulfamethoxazole (a sulfonamide antibiotic)
- Trimethoprim (often used in combination with sulfonamides)
- Fluoroquinolones (such as ciprofloxacin, which has a modified aromatic structure)
- Nitrofurantoin (an antibiotic with a heterocyclic aromatic ring)
- Tetracycline derivatives (some of which have aromatic components)

These examples are commonly used in the treatment of bacterial infections and are classified under this HS code based on their chemical structure.
