Benzilic Acid
Benzilic acid (2,2-diphenyl-2-hydroxyacetic acid) is a chemically defined organic compound with a carboxylic acid group, an alcohol function, and two phenyl groups on the alpha carbon. It is classified under tariff item 2918.17.00 as the named compound, regardless of purity or intended use.
2918.17.00Benzilic Acid Anhydride
Benzilic acid anhydride is a derivative of benzilic acid formed by dehydration of two acid molecules. Although not explicitly named in the tariff item, subheading note 1 classifies derivatives of a named compound in the same subheading if not more specifically covered elsewhere.
2918.17.00Benzilic Acid Pharmaceutical Grade
Pharmaceutical grade benzilic acid is high-purity (≥99.5%) benzilic acid meeting USP/EP standards, used as an intermediate in anticholinergic drug synthesis. It is the same chemically defined compound as benzilic acid and thus falls under tariff item 2918.17.00.
2918.17.00Benzilic Acid Research Grade
Research grade benzilic acid is ultra-high purity (99.9%) benzilic acid for laboratory research and NMR reference standards. As a chemically defined compound, it is classified under tariff item 2918.17.00 regardless of its small packaging or research purpose.
2918.17.00Benzilic Acid Sodium Salt
Benzilic acid sodium salt (sodium benzilate) is the sodium salt of 2,2-diphenyl-2-hydroxyacetic acid. Per chapter note 5(C)(1), inorganic salts of organic compounds are classified in the heading appropriate to the organic compound, so it falls under tariff item 2918.17.00.
2918.17.00Benzilic Acid Technical Grade
Technical grade benzilic acid (95-98% purity) is used for industrial synthesis. Despite lower purity, it remains a chemically defined compound under chapter note 1(a), as impurities do not alter its identity or general use. It is classified under tariff item 2918.17.00.
2918.17.00Benzilic Acid with Stabilizer
Benzilic acid with added stabilizer (e.g., 0.1% citric acid) for preservation is classified under tariff item 2918.17.00 per chapter note 1(f). The stabilizer is necessary for preservation or transport and does not render the product suitable for a specific use.
