Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formulated as insecticide for retail or agricultural use
Formulated pesticides containing chlordimeform as active ingredient shift to Chapter 38 heading for insecticides, not the pure compound.
If imported as a salt derivative rather than base imine
Certain imine salts may classify under heterocyclic compounds if structure fits Chapter 29 subheading 2933, based on chapter notes prioritizing last numerical order.
If dissolved in solvent for safe transport exceeding general use
Solutions of Chapter 29 compounds in solvents qualify under 3824 if prepared specifically for safety/transport and not rendered suitable for particular end-use per chapter note (e).
