Chemicals
View full HS code details

Estrogen is classified under HS code 293723 because it is a steroidal hormone, specifically categorized within the sub-group of oestrogens and progestogens. Chapter 29 of the Harmonized System covers organic chemicals, and heading 2937 is dedicated to hormones, prostaglandins, thromboxanes, and leukotrienes, whether natural or reproduced by synthesis. Since estrogen is a primary female sex hormone and its derivatives are used extensively in pharmaceutical manufacturing, it falls under this specific subheading. The classification is determined by the chemical structure of the molecule, which consists of a steroid nucleus. This code applies to the pure chemical substance or its derivatives, provided they are not yet formulated into a specific dosage form for therapeutic use. According to the General Rules of Interpretation (GRI 1), classification is determined by the terms of the headings and any relative section or chapter notes. Chapter 29 Note 8 specifies that hormones include hormone-releasing or hormone-stimulating factors. Estrogen, being a fundamental hormone, fits perfectly within this scope. The distinction between 293723 and other subheadings in 2937 depends on the specific chemical structure—oestrogens are characterized by their aromatic A-ring. This classification is vital for international trade as it allows customs authorities to monitor the movement of hormonal substances, which are often subject to strict regulatory oversight due to their biological activity.

Common Misclassification

Estrogen is frequently misclassified under HS code 3004 when it is imported in bulk. However, 3004 is reserved for medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale. Another common error is using 293729, which is a residual category for other steroidal hormones, whereas estrogen has its own specific sub-category in 293723.
