2837.19.01.10 - Potassium cyanide

This HTS classification covers potassium cyanide, a specific inorganic chemical compound. Within the broader category of "Cyanides, cyanide oxides and complex cyanides," this subheading focuses on binary cyanides of alkali metals, specifically when composed with potassium. Potassium cyanide is characterized by its chemical formula KCN and is recognized as a highly toxic salt.

Distinguishing this category from its siblings is crucial for accurate classification. While 2837.19.01.15 specifically enumerates calcium cyanide, this subheading is dedicated solely to potassium cyanide. The sibling category 2837.19.01.25, "Other," serves as a residual category for cyanides and cyanide oxides not otherwise specified within this level, thus excluding the specifically identified potassium and calcium cyanides.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification at this level is determined by the specific chemical identity of the cyanide compound. Therefore, any product meeting the chemical definition of potassium cyanide would fall under this HTS code, provided it is not a more complex cyanide compound covered elsewhere.
