3004.31.00.00 - Containing insulin

This HTS category, 3004.31.00.00, specifically covers medicaments in measured doses or for retail sale that contain insulin for therapeutic or prophylactic use. Insulin is a hormone crucial for regulating blood sugar levels, and products classified here are primarily intended to treat conditions such as diabetes. The classification applies whether the insulin is in its pure form or combined with other medicinal ingredients, as long as insulin is a defining component of the medicament.

Distinguishing this category from its siblings, 3004.31.00.00 is unique in its explicit focus on insulin. In contrast, 3004.32.00.00 deals with medicaments containing corticosteroid hormones, their derivatives, or structural analogues, which serve different therapeutic functions related to inflammation and immune response. The residual category, 3004.39.00, is for other medicaments containing hormones or products of heading 2937 not otherwise specified, meaning it captures a broader range of hormonal treatments beyond insulin and corticosteroids.

As a leaf node, 3004.31.00.00 does not have further subcategories. Therefore, the classification hinges directly on the presence and primary therapeutic role of insulin within the medicament. Examples of products that would fall under this heading include pre-filled insulin pens, vials of insulin for injection, and insulin nasal sprays, provided they meet the criteria of being put up in measured doses or in forms for retail sale for therapeutic or prophylactic purposes.
