Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily as an arsenical compound rather than organo-inorganic
Chapter 28 covers other inorganic arsenical compounds; if arsenic linkage doesn't emphasize organic character, it shifts from Chapter 29 organo-inorganics.
If for halogenated vinyl derivatives without direct metal-carbon bond emphasis
Halogenated hydrocarbons in 2903 if the organo-inorganic nature is secondary; Chapter notes exclude sulfonated/halogenated from 2931 if not qualifying as organo-inorganic.
If imported as a diluted solution or mixture for safety/transport
Chapter 29 note (e) allows solutions in solvents for safety, but if solvent renders it suitable for specific use, it falls to Chapter 38 as chemical preparations.
