Heading 2937

Hormones, prostaglandins, thromboxanes and leukotrienes, natural or reproduced by synthesis; derivatives and structural analogues thereof, including chain modified polypeptides, used primarily as hormones

29 declarable lines

Heading 2937 covers hormones, prostaglandins, thromboxanes and leukotrienes, whether natural or reproduced by synthesis, plus their derivatives and structural analogues used primarily as hormones. It splits into four groups: polypeptide, protein and glycoprotein hormones (2937.11 through 2937.19), steroidal hormones (2937.21 through 2937.29), prostaglandins, thromboxanes and leukotrienes (2937.50), and other hormones such as catecholamines and amino-acid derivatives (2937.90). Every declarable line in this heading carries a general (MFN) rate of Free.

Products in this heading

  • Insulin and its salts
  • Somatotropin (growth hormone) and its derivatives
  • Hydrocortisone and its salts and esters
  • Prednisone and prednisolone
  • Dexamethasone and its salts
  • Progesterone
  • Epinephrine and epinephrine hydrochloride
  • Levothyroxine sodium

How to choose the right subheading

  • Hormone type: polypeptide or protein hormone, steroidal hormone, prostaglandin family, or other (catecholamine, amino-acid derivative).
  • Whether the product is the natural hormone or reproduced by synthesis, since both are covered but the named compound decides the line.
  • The specific chemical identity (for example hydrocortisone versus prednisolone) because many subheadings name individual compounds.
  • Whether the goods are the base compound, a salt, or an ester, as salts and esters often have separate lines.
  • For estrogens and progestins, whether the material is obtained directly or indirectly from animal or vegetable materials.

Often confused with

  • Vitamin D3 (cholecalciferol) and other vitamins

    Vitamins and provitamins are covered by heading 2936, not as hormones.

    Heading 2936
  • Penicillins and other antibiotics

    Antibiotics have their own heading even when produced by fermentation.

    Heading 2941
  • Digitalis glycosides and other glycosides

    Glycosides separated from their aglycone go to heading 2938.

    Heading 2938
  • Caffeine and other alkaloids

    Alkaloids of plant origin are classified in heading 2939.

    Heading 2939
  • Lysine and other amino acids sold as chemicals
