Overview

This HTS classification covers Prednisolone, a synthetic corticosteroid. Prednisolone is a potent anti-inflammatory and immunosuppressant medication, widely used in human and veterinary medicine to treat a variety of conditions including allergies, asthma, autoimmune diseases, and certain cancers. Its classification falls under steroidal hormones and their derivatives due to its chemical structure and biological function, mirroring that of naturally occurring corticosteroids.

Prednisolone (HTS 2937.21.00.40) is distinct from its sibling categories by its specific chemical structure and therapeutic application. Cortisone (2937.21.00.10) and Hydrocortisone (2937.21.00.20) are related corticosteroids, but differ in their molecular configuration and potency. Prednisone (2937.21.00.30) is a pro-drug that is converted to prednisolone in the body; while closely related, it is classified separately based on its initial chemical form.

As a leaf node, this classification for Prednisolone does not have further subdivisions. Therefore, the focus remains on accurately identifying and classifying pure Prednisolone, as well as preparations or mixtures containing Prednisolone when such specific entries do not exist elsewhere in the HTS. Classification at this level relies on the precise chemical identification of the substance to ensure accurate trade reporting and duty assessment.
