2937.21.00.20 - Hydrocortisone

This HTS classification covers hydrocortisone, a specific corticosteroid hormone. Hydrocortisone is a naturally occurring steroid hormone produced by the adrenal cortex, and also synthetically produced for medicinal purposes. It plays a crucial role in various physiological processes, including regulating metabolism, immune response, and reducing inflammation. Its applications are widespread in pharmaceuticals for treating conditions such as allergies, asthma, arthritis, and skin disorders.

Within the broader category of steroidal hormones, this code is specifically reserved for hydrocortisone. It is distinguished from its sibling categories by its unique chemical structure and biological activity. For example, cortisone (2937.21.00.10) is a precursor to hydrocortisone and has a weaker anti-inflammatory effect. Prednisone (2937.21.00.30) and prednisolone (2937.21.00.40) are synthetic derivatives with enhanced anti-inflammatory potency compared to hydrocortisone.

As a leaf node within the HTS classification system, the code 2937.21.00.20 does not have further subdivisions. Therefore, all forms and preparations of hydrocortisone, regardless of purity or dosage form, would generally fall under this specific classification, provided they meet the defined chemical criteria. The primary focus for classification here remains the identification of the substance as hydrocortisone itself, based on its chemical identity and its function as a steroidal hormone.
