U.S. imports of estrogens and progestins (HS 293723) totaled $3.2M in August 2026, imported from 14 countries.
Importers of Estrogens and Progestins paid $55K in duties in August 2026, an effective tariff rate of 1.71% of the $3.2M imported — duty actually collected as a share of that value, not the published tariff schedule. Estrogens and Progestins imports of $3.2M in August 2026 ran 52% below the year-to-date monthly average of $6.8M.
Last updated: August 2026 dataEstrogens and progestins are steroidal sex hormones widely used as APIs in contraceptives, hormone replacement therapies, and veterinary products, and the US tariff schedule subdivides them by origin (animal/vegetable versus synthetic) and by specific compound, with named lines for estradiol benzoate, estradiol cyclopentyl propionate, and progesterone. China is the dominant supplier, followed by Spain and the Netherlands, reflecting the global concentration of steroid-hormone synthesis in Asia and Europe. Imports subject to Section 301 measures from China may carry additional duties, making origin documentation and supplier diversification strategically important for pharmaceutical manufacturers. All shipments require FDA admissibility review as pharmaceutical-grade chemical intermediates or finished APIs.

The schedule draws a clear origin-based line: estrogens, progesterone, and other progestins derived from animal or vegetable material classify under separate 10-digit lines (2937231010, 2937231020, 2937235010, 2937235020, and related codes) from their synthetically derived counterparts. Importers must document the manufacturing pathway — typically via a Certificate of Analysis or supplier declaration — to support the correct classification, as the duty treatment may differ.
Yes. Imports of these compounds from China may be subject to Section 301 tariffs. The applicable additional duty depends on the specific 10-digit HTS line and the current Section 301 list status. Importers should verify the current list coverage and rate with a licensed customs broker before entry, as list modifications and exclusions change periodically. Consult a licensed customs broker for current admissibility and duty guidance.
