2926.30.20.00 - 4-Cyano-2-dimethylamino-4,4-diphenylbutane

This HTS classification, 2926.30.20.00, specifically covers the compound 4-Cyano-2-dimethylamino-4,4-diphenylbutane. This substance is recognized in the chemical industry and is also referred to as Methadone intermediate. Its classification is rooted within Chapter 29, which deals with organic chemicals, and more specifically under the heading for nitrile-function compounds.

This category is distinct from its sibling category, 2926.30.10.00, which covers Fenproporex (INN) and its salts. While both fall under the broader heading of nitrile-function compounds and are related to pharmaceutical precursors or active ingredients, 2926.30.20.00 is exclusively for the specified diphenylbutane derivative. The distinction lies in the precise chemical structure and identity of the compound being classified.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification at this level is definitive for 4-Cyano-2-dimethylamino-4,4-diphenylbutane. Importers and exporters should rely on the precise chemical name and structure to ensure accurate declaration and duty assessment for this specific organic chemical.
