Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formulated as a pesticide for retail or agricultural use
Formulated pesticide products containing Myclobutanil as active ingredient shift to Chapter 38 headings for insecticides, rodenticides, and fungicides.
If non-aromatic or modified non-aromatic triazole derivative
Chapter notes specify aromatic compounds in 2933.99.06.00; other heterocyclic nitrogen compounds go to the residual 2933.99.9700 subheading.
If imported as a salt of this organic compound
Organic salts are classified with the parent compound per chapter note 3(C)(1), but other salts may fall under heading 2942 for miscellaneous nitrogen-function compounds.
