About heading 2837
Cyanides, cyanide oxides and complex cyanides
Heading 2837 covers cyanides, cyanide oxides and complex cyanides, which are inorganic salts built around the cyanide ion. The heading splits first by type: simple cyanides and cyanide oxides in 2837.11 and 2837.19, and complex cyanides in 2837.20. Within simple cyanides, sodium has its own line, while potassium, calcium and other cations fall under the residual subheadings.
