Dicyandiamide (1-Cyanoguanamide)
Dicyandiamide, also known as 1-cyanoguanidine, is a white crystalline powder classified under HTS 2926.20.00.00 as a nitrile-function compound due to its cyano group (-Cā”N) attached to the guanidine structure. It serves as a key intermediate in organic synthesis for epoxy resins and pharmaceuticals.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed primarily as a guanidine derivative without emphasizing nitrile function
Guanidines fall under heading 2925; classification prioritizes the last numerical heading per chapter note, but principal function may shift to guanidine if nitrile is secondary.
If when imported as a formulated mixture with stabilizers exceeding chapter note limits
Mixtures not qualifying as pure compounds under chapter notes (a)-(g) shift to Chapter 38 prepared binders or chemical mixtures.
If diluted and put up specifically for agricultural fertilizer use
Urea derivatives like dicyandiamide in fertilizer preparations are excluded from Chapter 29 per note 2(f) and classified in Chapter 31.
