Products classified under HTS 2937.50.00.00
Misoprostol
Misoprostol is a synthetic prostaglandin E1 analogue used primarily for preventing NSAID-induced gastric ulcers and inducing labor. It falls under HTS 2937.50.00.00 as a prostaglandin derivative and structural analogue used primarily as a hormone. This classification applies to its chemically defined organic structure meeting Chapter 29 requirements.
Carboprost Tromethamine
Carboprost tromethamine is a synthetic prostaglandin F2α analogue used for postpartum hemorrhage control. Falls under HTS 2937.50.00.00 as a prostaglandin derivative with hormonal activity. The tromethamine salt classifies with the parent prostaglandin per Chapter 29 salt rules.
Latanoprost
Latanoprost is a prostaglandin F2α analogue used in ophthalmic solutions for glaucoma treatment. Classified under HTS 2937.50.00.00 due to its primary hormonal mechanism reducing intraocular pressure. Chemically defined structure qualifies under Chapter 29 organic compounds.
Travoprost
Travoprost is a synthetic prostaglandin F2α isopropyl ester analogue for glaucoma therapy. Classified under HTS 2937.50.00.00 following Chapter 29 ester rules (classifies with parent acid-function compound). Used primarily for its hormonal IOP-lowering effect.
Tafluprost
Tafluprost, a fluorinated prostaglandin F2α analogue, is used in glaucoma treatment with preserved formulations. Falls under HTS 2937.50.00.00 as a halogenated prostaglandin derivative per Chapter 29 notes. Primary hormonal mechanism confirmed by receptor binding studies.
Alprostadil
Alprostadil (Prostaglandin E1) is used for erectile dysfunction and maintaining patent ductus arteriosus. Classified under HTS 2937.50.00.00 as a prostaglandin with primary hormonal vascular effects. Chemically pure form qualifies as Chapter 29 organic compound.
Iloprost
Iloprost is a stable prostacyclin analogue (PGI2) used for pulmonary hypertension. Falls under HTS 2937.50.00.00 as a prostaglandin structural analogue with hormonal vasodilatory effects. Modified double bond structure maintains classification.
Treprostinil
Treprostinil is a stable prostacyclin analogue for pulmonary hypertension via multiple administration routes. Falls under HTS 2937.50.00.00 as a prostaglandin structural analogue with hormonal activity. Tricyclic structure maintains classification.
Unoprostone Isopropyl
Unoprostone isopropyl, a docosanoid prostaglandin F2α isomer, treats glaucoma. Classified under HTS 2937.50.00.00 as prostaglandin ester structural analogue per Chapter 29 ester rules. Longer chain maintains hormonal classification.
Limaprost Alfa
Limaprost alfa, a synthetic prostaglandin E1 derivative, treats peripheral vascular disease. Falls under HTS 2937.50.00.00 as modified prostaglandin with hormonal activity. Alfa-dextran complex classifies as derivative.
Beraprost Sodium
Beraprost sodium, an oral prostacyclin analogue, treats peripheral arterial disease. Classified under HTS 2937.50.00.00 as stable PGI2 structural analogue salt. Oral bioavailability maintains hormonal classification.
Prostaglandin D2 (PGD2)
Prostaglandin D2 (PGD2), a natural prostanoid mediator of allergic responses, used in research. Falls under HTS 2937.50.00.00 as naturally occurring prostaglandin reproduced by synthesis. Chemically defined for Chapter 29 classification.
Dinoprostone
Dinoprostone (Prostaglandin E2) is a naturally-derived prostaglandin used for cervical ripening and labor induction. Classified under HTS 2937.50.00.00 as a prostaglandin reproduced by synthesis or its derivatives used primarily as hormones. Meets Chapter 29 criteria for separate chemically defined organic compounds.
Bimatoprost
Bimatoprost, a prostamide analogue of prostaglandin F2α, is used for glaucoma and eyelash hypotrichosis. Falls under HTS 2937.50.00.00 as a structural analogue with primary hormonal activity. Chapter 29 applies to its chemically defined organic structure.
Epoprostenol Sodium
Epoprostenol sodium (prostacyclin, PGI2) treats pulmonary arterial hypertension via continuous IV infusion. Classified under HTS 2937.50.00.00 as prostaglandin salt following parent compound per Chapter 29 rules. Requires immediate use due to chemical instability.
