2837 - Cyanides, cyanide oxides and complex cyanides:

Sub-classifications

Commodity Code
Description

Overview

This HTS category, 2837, encompasses a specific group of inorganic chemical compounds: cyanides, cyanide oxides, and complex cyanides. These substances are characterized by the presence of the cyanide group (CN) within their molecular structure. They are generally highly reactive and often employed as intermediates in various industrial processes, including mining (for precious metal extraction), electroplating, and the production of dyes and pharmaceuticals. It is crucial to note that while this chapter covers inorganic compounds, organic cyanides would fall under Chapter 29.

Distinguishing this category from its siblings at the HTS Root level is straightforward. The sibling categories are primarily concerned with live animals, ranging from horses and bovine animals to sheep, goats, and poultry. HTS 2837, conversely, deals exclusively with chemical substances, specifically certain inorganic cyanide compounds, and has no relation to agricultural products or live organisms.

Within HTS 2837, two primary subcategories exist to further refine classification. The first, indicated by a blank HTS code, covers simple cyanides and cyanide oxides. The second, HTS 2837.20, specifically addresses complex cyanides, which are compounds where the cyanide group is coordinated to a central metal atom. This subdivision allows for more precise identification based on the structural arrangement and chemical properties of the cyanide compound.
