2926.20.00.00 - 1-Cyanoguanidine (Dicyandiamide)

This HTS category, 2926.20.00.00, specifically classifies 1-Cyanoguanidine, commonly known as Dicyandiamide. Dicyandiamide is an organic chemical compound that serves as a crucial intermediate in various industrial applications, most notably in the production of guanidine salts, flame retardants, and epoxy resin curing agents. Its classification under Chapter 29, which covers organic chemicals, is consistent with its molecular structure and chemical properties.

Within the broader "Nitrile-function compounds" group, 2926.20.00.00 is distinct from its sibling categories. For instance, 2926.10.00.00 covers Acrylonitrile, a simpler nitrile used extensively in polymer manufacturing. Similarly, 2926.30 pertains to specific compounds like Fenproporex and methadone intermediates, which have distinct chemical structures and uses. 2926.40.00.00 is reserved for alpha-Phenylacetoacetonitrile, another compound with a unique phenyl-substituted structure. 2926.90 encompasses all other nitrile-function compounds not specifically enumerated elsewhere in this heading.

As 2926.20.00.00 represents a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification of Dicyandiamide is definitive at this level. When classifying materials, emphasis is placed on the precise identification of 1-Cyanoguanidine by its chemical name or common synonym, differentiating it from other nitrile-containing compounds based on its specific molecular formula and industrial applications.
