2937.19.00.00 - Other

This HTS category, 2937.19.00.00, encompasses polypeptide hormones, protein hormones, and glycoprotein hormones, along with their derivatives and structural analogues, that are not specifically classified elsewhere within the 2937.1x series. These substances are characterized by their peptide or protein structure and are primarily utilized for their hormonal effects, either naturally occurring or synthetically produced. Their applications often span therapeutic treatments and other physiological regulatory functions within living organisms.

This residual category serves to capture various peptide-based hormones that do not fall under the more specific classifications of somatotropin (2937.11.00.00) or insulin and its salts (2937.12.00.00). Unlike somatotropin, which is specifically human growth hormone, or insulin, essential for glucose regulation, the goods under 2937.19.00.00 are diverse and can include other peptide hormones like follicle-stimulating hormone (FSH), luteinizing hormone (LH), parathyroid hormone (PTH), calcitonin, or glucagon, as well as their modified synthetic versions designed for specific pharmaceutical or research purposes.

As this is a leaf node, there are no further subcategories. The classification of a product under 2937.19.00.00 relies on its chemical identity as a polypeptide, protein, or glycoprotein hormone and its primary function. If a substance is a peptide or protein hormone but has a distinctly different primary use (e.g., purely as a diagnostic reagent or a structural protein with no hormonal effect), it would be classified elsewhere.
