Overview
This HTS category, 2937.12.00.00, specifically covers insulin and its salts. Insulin is a polypeptide hormone produced by the pancreas that regulates carbohydrate metabolism. This classification encompasses both naturally derived and synthetically produced insulin, as well as any salts formed from insulin. The primary function and biological activity of regulating blood glucose levels are key defining characteristics for goods falling under this heading.
Distinguishing this category from its siblings, 2937.11.00.00 covers somatotropin (growth hormone) and its derivatives, which have different physiological functions related to growth and development. The sibling category 2937.19.00.00, "Other," acts as a residual category for polypeptide hormones, protein hormones, and glycoprotein hormones not elsewhere specified. Therefore, the precise biological function and chemical structure are crucial in differentiating insulin from these other related hormone categories.
As a leaf node, 2937.12.00.00 does not have further subcategories. Goods classified here are considered specific enough to warrant direct classification without further subdivision. Classification decisions within this heading will therefore focus on confirming the identity of the substance as insulin or a salt thereof, based on its chemical composition and intended therapeutic use in regulating blood sugar.
