Overview
This HTS category, 2937.23.25.00, specifically classifies estradiol benzoate and estradiol cyclopentylpropionate (also known as estradiol cypionate). These are synthetic derivatives of the naturally occurring estrogen, estradiol, used primarily for their hormonal properties. Estradiol benzoate is typically used in veterinary medicine as a long-acting estrogen, while estradiol cypionate is commonly employed in human medicine as a component of hormone replacement therapy and in contraceptives.
This classification stands apart from other siblings at the same level by its precise identification of these two specific ester derivatives of estradiol. While other "Other" categories under 2937.23.00 might encompass different steroidal hormone esters or other less common hormonal compounds, this subcategory is narrowly defined to include only these two well-established pharmaceutical preparations.
As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, classification under 2937.23.25.00 is definitive once the product is identified as either estradiol benzoate or estradiol cyclopentylpropionate, aligning with the established scope of steroidal hormones, their derivatives, and structural analogues used primarily as hormones.
