3004.90.92.25 - Tolmetin sodium (anhydrous)

This HTS code encompasses pharmaceutical preparations containing tolmetin sodium in its anhydrous form. These medicaments are intended for therapeutic or prophylactic purposes and are packaged for direct use, such as in measured doses or for retail sale. As part of Chapter 30, they are recognized for their medicinal qualities.

This specific classification distinguishes itself by the chemical state of the active ingredient. While other sibling categories might cover tolmetin in its general form or as a dihydrate salt, or medicaments containing different active pharmaceutical ingredients like ibuprofen, acetaminophen, or aspirin, this code is exclusively for tolmetin sodium that is anhydrous, meaning it contains no water molecules within its crystalline structure. This distinction is critical for accurate customs declaration and duty assessment.

As this node is a leaf node in the HTS, there are no further subcategories. Therefore, the classification is definitive for anhydrous tolmetin sodium preparations. Examples falling under this code would include any finished pharmaceutical products where the sole or primary active ingredient is anhydrous tolmetin sodium, presented in a form ready for administration to patients for its anti-inflammatory and analgesic properties.
