2905.12.00.50 - Propan-2-ol

This HTS category, 2905.12.00.50, specifically classifies propan-2-ol, also commonly known as isopropyl alcohol or isopropanol. Propan-2-ol is a saturated monohydric acyclic alcohol characterized by the presence of a hydroxyl group attached to the second carbon atom of a three-carbon chain. It is a colorless, flammable liquid with a characteristic odor and is widely used as a solvent, cleaning agent, and disinfectant due to its ability to dissolve a variety of nonpolar compounds and its relatively low toxicity compared to other alcohols.

Within the broader classification of saturated monohydric alcohols, this specific subcategory is distinguished from its sibling, 2905.12.00.10, which covers propan-1-ol. While both are three-carbon monohydric alcohols, the key difference lies in the position of the hydroxyl group. Propan-1-ol has the hydroxyl group attached to the first carbon atom, resulting in different physical and chemical properties and consequently, distinct industrial applications. This distinction is crucial for accurate tariff classification.

As this is a leaf node in the HTS structure, there are no further subcategories under 2905.12.00.50. Therefore, the classification ends with the specific identification of propan-2-ol. Importers and exporters should ensure that the product being declared precisely matches the chemical structure and common names associated with propan-2-ol to ensure compliance with customs regulations.
