Overview

This classification, 2937.29.90.30, specifically designates salts and esters derived from prednisone. Prednisone is a synthetic corticosteroid hormone, and this category encompasses various chemical modifications of prednisone in its salt or ester form. These compounds are primarily utilized for their anti-inflammatory and immunosuppressive properties in pharmaceutical applications, ranging from treatment of allergic conditions to autoimmune diseases.

This HTS code is distinguished from its siblings by the specific parent steroid from which the salt or ester is derived. For instance, 2937.29.90.20 covers salts and esters of hydrocortisone, a related but distinct corticosteroid. Similarly, 2937.29.90.40 pertains to salts and esters of prednisolone, which is the active metabolite of prednisone. The category 2937.29.90.50 is reserved for anabolic agents and androgens, a completely different class of steroidal hormones.

As a leaf node, this classification has no further subdivisions. Therefore, the focus for classification under 2937.29.90.30 is on ensuring the goods are indeed salts or esters of prednisone and are not specifically covered by other, more granular descriptions within the broader "Other" category for steroidal hormones and their derivatives. The precise chemical structure and intended pharmaceutical use are key criteria for accurate classification.
