Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified by phosphorus content as phosphides
Phosphides n.e.s. in 2819 cover inorganic phosphorus compounds, but cyanogen chloride's cyanogen structure takes precedence under Chapter 28 notes.
If containing >1% organic compounds
Organic compounds of cyanogen fall in Chapter 29; pure inorganic cyanogen chloride remains in Chapter 28 per chapter note 2(e).
If imported as mixture or solution for lab use
Chemical preparations n.e.s. in 3824 apply to mixtures, while chemically defined pure compounds stay in their specific Chapter 28 heading.
