About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This classification covers calcium cyanide, a chemical compound with the formula Ca(CN)â‚‚. It is an inorganic salt formed from calcium and cyanide ions. Calcium cyanide finds various industrial applications, including its use as a mining reagent, a soil fumigant, and in the extraction of gold and silver.

Within the broader category of "Cyanides and cyanide oxides," this specific subheading distinguishes itself from its sibling, potassium cyanide (HTS 2837.19.01.10). While both are metal cyanides, the key differentiating factor is the metallic cation. This subheading is exclusively for the calcium salt, whereas the sibling is for the potassium salt.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification under 2837.19.01.15 is definitive for calcium cyanide. Therefore, any importation or exportation of calcium cyanide, irrespective of its purity, form (e.g., solid, solution), or specific end-use, will be classified under this HTS code.
