3001 - Glands and other organs for organotherapeutic uses, dried, whether or not powdered; extracts of glands or other organs or of their secretions for organotherapeutic uses; heparin and its salts; other human or animal substances prepared for therapeutic or prophylactic uses, not elsewhere specified or included:

This HTS category, 3001, encompasses a range of animal-derived substances specifically prepared for medicinal and prophylactic purposes. It includes dried glands and organs, which can be in their natural state or powdered. Furthermore, it covers extracts derived from these glands or organs, as well as their secretions, all intended for therapeutic use. Heparin and its salts are also specifically listed within this classification, along with other human or animal substances that have been prepared for medicinal or preventive applications but are not classified elsewhere within the Harmonized System.

Distinguishing this category from its siblings at the HTS root level is straightforward. HTS codes starting with '01' relate to live animals, such as horses, cattle, swine, sheep, goats, and poultry. HTS 3001, conversely, deals with processed animal-derived materials prepared for pharmaceutical use, not live animals themselves. This separation is crucial for customs purposes, as it segregates live animal imports from their processed byproducts used in the medical field.

Within HTS 3001, subcategories are further defined to specify the form and type of these organotherapeutic substances. The primary subdivisions are for "Extracts of glands or other organs or of their secretions" (3001.20.00.00) and "Other" (3001.90.01), which accounts for dried glands, powdered organs, heparin, and other miscellaneous prepared animal substances for therapeutic uses. This detailed breakdown allows for more precise classification based on whether the product is an extract or a different form of organotherapeutic material.
