Overview
This HTS classification covers salts and esters of prednisolone. Prednisolone is a synthetic corticosteroid that mimics the actions of natural glucocorticoids produced by the adrenal glands. Its salts and esters are chemical derivatives designed to alter properties such as solubility, stability, or duration of action, making them suitable for various pharmaceutical applications, particularly in anti-inflammatory and immunosuppressive therapies.
Within the broader category of steroidal hormones and their derivatives, this specific subheading distinguishes itself by its focus solely on prednisolone-based compounds. It is differentiated from sibling categories such as 2937.29.90.20 (salts and esters of hydrocortisone) and 2937.29.90.30 (salts and esters of prednisone) by the specific parent steroidal hormone from which the salt or ester is derived. Additionally, it is distinct from 2937.29.90.50 (anabolic agents and androgens), which represent a different class of steroid with distinct physiological effects.
As a leaf node, 2937.29.90.40 has no further subcategories. Classification at this level is determined by the chemical identity of the salt or ester as being derived from prednisolone. Examples of such compounds include prednisolone sodium phosphate, prednisolone acetate, and prednisolone hemisuccinate, all of which would fall under this specific tariff code when imported or exported. The classification relies on the precise chemical structure and the fact that it is a derivative of prednisolone.
