Products classified under HTS 2937.23.50.50
Estradiol Valerate
Estradiol valerate is a synthetic ester of the natural estrogen hormone estradiol, used primarily in hormone replacement therapy and contraception. It falls under HTS 2937.23.5050 as a steroidal estrogen derivative and structural analogue used primarily as a hormone. This classification applies to its chemically defined organic structure per Chapter 29 notes.
Norethindrone Acetate
Norethindrone acetate is a synthetic progestin used in oral contraceptives and hormone therapy, structurally derived from 19-nortestosterone. Classified under HTS 2937.23.5050 as a progestin derivative used primarily as a hormone per Chapter 29 definitions. Its organic compound nature and hormonal function determine this specific tariff placement.
Levonorgestrel
Levonorgestrel is a synthetic progestogen used in emergency contraception and intrauterine devices, a derivative of norethindrone. It qualifies for HTS 2937.23.5050 as a structural analogue of progestins used primarily as hormones. Chapter 29 notes confirm classification based on its primary hormonal function.
Medroxyprogesterone Acetate
Medroxyprogesterone acetate is a synthetic progestin derivative used for contraception, endometriosis treatment, and cancer therapy. Falls under HTS 2937.23.5050 as an 'other' steroidal progestin hormone per the tariff hierarchy. Its classification follows Chapter 29 rule of last numerical heading for multi-function compounds.
Etonogestrel
Etonogestrel is the active metabolite of desogestrel, used in contraceptive implants and vaginal rings as a synthetic progestin. Classified under HTS 2937.23.5050 as a structural analogue of progestins used primarily as hormones. Meets Chapter 29 requirements for separate chemically defined organic compounds.
Norgestimate
Norgestimate is a third-generation progestin used in combination oral contraceptives, a derivative with ethinyl estradiol. It falls under HTS 2937.23.5050 as an 'other' progestin structural analogue used primarily as a hormone. Chapter 29 notes confirm its classification over earlier organic function headings.
Drospirenone
Drospirenone is a synthetic spironolactone analogue with progestogenic and antimineralocorticoid activity, used in oral contraceptives. Classified in HTS 2937.23.5050 as a steroidal progestin derivative used primarily as a hormone. Its unique structure still qualifies under Chapter 29 hormone provisions.
