Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of a pesticide formulation exceeding 50% purity
Pesticide active ingredients classified by function fall under Chapter 29 subheading 2933, taking precedence over general nitrogen compounds per chapter notes.
If sold as a salt derivative rather than free isocyanate
Inorganic salts of organic nitrogen compounds are classified with the organic base per chapter note 3(C)(1), potentially shifting to carboxamide/amide headings if structure fits.
If diluted in solvent for safety/transport beyond chapter allowances
Solutions exceeding 'normal' safety/transport criteria per chapter note (e) may classify as chemical preparations in 3824 rather than pure compounds.
