Description

This heading encompasses a broad range of biologically active compounds, including natural hormones, prostaglandins, thromboxanes, leukotrienes, and their synthetic reproductions. It also covers derivatives and structural analogues such as chain-modified polypeptides primarily used as hormones in medical and pharmaceutical applications.

Key categories within this code include:

  • Peptide Hormones: Including somatotropin (growth hormone) and its structural analogues.
  • Insulins and Salts: Various forms of insulin used for diabetes treatment.
  • Corticosteroids: Such as cortisone, hydrocortisone, prednisone, and prednisolone, including their halogenated derivatives and salts/esters.
  • Sex Hormones: Estrogens and progestins, both naturally derived and synthetic, including specific esters like estradiol benzoate and estradiol cypionate.
  • Other Hormonal Agents: Anabolic agents, androgens, and other miscellaneous hormones.
  • Prostaglandins, Thromboxanes, Leukotrienes: Their derivatives and structural analogues used in various therapeutic contexts.
  • Miscellaneous Others: Epinephrine and levothyroxine (thyroxine), among others.

Code Hierarchy

  • Section VI: Products of the Chemical or Allied Industries (Chapters 28-38)
  • Chapter 29: Organic Chemicals
  • Heading 2937: Hormones, prostaglandins, thromboxanes and leukotrienes, natural or reproduced by synthesis; derivatives and structural analogues thereof.
  • US HTS Code (10-digit): 2937.XX.XXXX – The last digits specify exact compounds or derivative types.
