Products classified under HTS 2937.19.00.00
Synthetic Oxytocin
Oxytocin is a polypeptide hormone reproduced by synthesis, used primarily for its hormonal effects in inducing labor and controlling bleeding after childbirth. It falls under HTS 2937.19.00.00 as a polypeptide hormone derivative used primarily as a hormone. This classification applies to its pure chemical form for pharmaceutical use.
Recombinant Human Growth Hormone (Somatropin)
Somatropin is a recombinant protein hormone structurally identical to human growth hormone, used to treat growth disorders. Classified under HTS 2937.19.00.00 as a protein hormone structural analogue used primarily as a hormone. This covers the bulk active pharmaceutical ingredient.
Synthetic Calcitonin Salmon
Calcitonin from salmon, reproduced synthetically, is a polypeptide hormone used primarily for treating osteoporosis and hypercalcemia. It qualifies under HTS 2937.19.00.00 as a polypeptide hormone derivative. The classification reflects its primary hormonal therapeutic use.
Desmopressin Acetate
Desmopressin is a synthetic analogue of vasopressin, a polypeptide hormone used for diabetes insipidus and bedwetting. Falls under HTS 2937.19.00.00 as a structural analogue of polypeptide hormones used primarily as hormones. Covers the pure chemical entity.
Recombinant Human Insulin (Bulk)
Recombinant human insulin is a protein hormone produced via biotechnology, used primarily for diabetes management. Classified in HTS 2937.19.00.00 as a protein hormone used primarily as a hormone. This applies to bulk API before formulation.
Glucagon (Recombinant)
Glucagon is a polypeptide hormone used to treat severe hypoglycemia, reproduced synthetically or recombinantly. It falls under HTS 2937.19.00.00 as a polypeptide hormone used primarily as a hormone. Classification based on its primary hormonal function.
Teriparatide (PTH 1-34)
Teriparatide is a synthetic polypeptide fragment of parathyroid hormone used for osteoporosis treatment. Classified under HTS 2937.19.00.00 as a polypeptide hormone structural analogue used primarily as a hormone. Covers the active recombinant protein.
Secretin (Synthetic)
Secretin is a gastrointestinal polypeptide hormone used diagnostically, available in synthetic form. Falls under HTS 2937.19.00.00 as a polypeptide hormone used primarily as a hormone. Classification reflects its chemical structure and hormonal nature.
Pramlintide Acetate
Pramlintide is a synthetic analogue of amylin, a polypeptide hormone co-secreted with insulin. Used primarily as a hormone adjunct in diabetes treatment, classified under HTS 2937.19.00.00. This covers the bulk acetate salt form.
Enfuvirtide (Synthetic Peptide Hormone Analogue)
Enfuvirtide is a synthetic polypeptide used as HIV entry inhibitor, functioning as hormone structural analogue. Though antiviral, its polypeptide hormone-like structure places it in HTS 2937.19.00.00 when used primarily as hormone analogue.
