2937.29.90.50 - Anabolic agents and androgens

This HTS category, 2937.29.90.50, encompasses anabolic agents and androgens. These are synthetic or naturally derived compounds that promote tissue growth and development, particularly muscle mass, and exhibit male sex hormone characteristics. Their application can range from therapeutic uses, such as treating conditions characterized by muscle wasting, to performance enhancement, although the latter is often subject to strict regulations and prohibitions. This classification is relevant for substances that are structurally related to steroids and exhibit androgenic or anabolic activity.

Distinguishing this category from its siblings, such as salts and esters of specific corticosteroids like hydrocortisone, prednisone, and prednisolone (2937.29.90.20, 2937.29.90.30, and 2937.29.90.40 respectively), is crucial. While those categories focus on specific, often anti-inflammatory, steroidal hormones and their salt or ester forms, 2937.29.90.50 covers a broader spectrum of androgenic and anabolic compounds that may not be primarily identified by their anti-inflammatory properties. The "Other" designation in the sibling category 2937.29.90.95 indicates substances that are steroidal hormones, derivatives, or structural analogues but do not fall into the more specifically enumerated subcategories of salts and esters of hydrocortisone, prednisone, or prednisolone.

As this node represents a leaf node within the HTS structure, there are no further subcategories. Therefore, classification into 2937.29.90.50 relies on identifying a substance as an anabolic agent or androgen that is a steroidal hormone, derivative, or structural analogue, and which is not specifically classified elsewhere under the broader steroidal hormones heading. Practical classification considerations will involve examining the chemical structure, primary physiological effect (anabolic or androgenic activity), and intended use of the substance in question.
