2837.19.01 - Other

This HTS category, "Other," under the heading 2837.19, pertains to cyanides and cyanide oxides that are not specifically classified elsewhere within this subheading. It encompasses a variety of inorganic cyanide compounds and their oxides that do not fall under the more specific subheadings for sodium cyanide. The classification here is determined by the absence of specific provisions for other named cyanides or cyanide oxides within the broader heading.

Distinguishing this category from its sibling, 2837.11.00.00, is straightforward. The sibling specifically covers cyanides and cyanide oxides of sodium. Therefore, this "Other" category serves as a residual classification for all other inorganic cyanides and cyanide oxides, excluding those made from sodium. This ensures that all such chemical compounds find a place within the HTS, preventing misclassification and facilitating accurate trade documentation.

Within this "Other" classification, further subdivisions exist to provide more granular detail for specific compounds. These subcategories include "Potassium cyanide," "Calcium cyanide," and a further "Other" for any remaining, less common cyanide compounds. This hierarchical structure allows for precise identification and reporting of different types of cyanides and cyanide oxides, which is crucial for regulatory compliance, statistical tracking, and the application of specific duties or controls that may apply to individual substances.
