About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This classification covers Prednisone, a synthetic corticosteroid hormone. Prednisone is a prodrug that is converted to its active form, prednisolone, in the body. It is primarily used for its anti-inflammatory and immunosuppressive properties in the treatment of a wide range of medical conditions.

This specific heading distinguishes Prednisone from its sibling categories based on its chemical structure and therapeutic application. Cortisone and Hydrocortisone are natural or synthetically reproduced corticosteroid hormones with different chemical structures and potency. Prednisolone, while closely related as the active metabolite of Prednisone, is a distinct chemical entity and therefore classified separately.

As this is a leaf node in the HTS, there are no further subdivisions for Prednisone. Classification at this level is precise, focusing on the identification of Prednisone itself as a distinct pharmaceutical substance within the broader category of steroidal hormones.
