Overview

This HTS category, 2941.10.10.00, specifically covers Ampicillin and its salts. Ampicillin is a broad-spectrum penicillin antibiotic widely used in both human and veterinary medicine to treat bacterial infections. This classification encompasses the pure chemical substance Ampicillin, as well as any chemically recognized salts derived from it, provided they meet the structural requirements of penicillins.

Distinguishing this category from its sibling, 2941.10.20.00, is crucial. While both fall under the broader heading of "Penicillins and their derivatives with a penicillanic acid structure; salts thereof," this node is exclusively for Ampicillin. The sibling category, 2941.10.20.00, is designated for Penicillin G salts. Therefore, importers must accurately identify the specific penicillin derivative being imported to ensure correct classification.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 2941.10.10.00 is definitive once the product is confirmed to be Ampicillin or its salts, and it is not Penicillin G or another distinct penicillin derivative. The focus for classification at this level is the precise chemical identity of the antibiotic.
