Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formulated as a complete fungicide with active ingredients
Pesticides containing sulfur as active matter classify under Chapter 38, not pure colloidal sulfur.
If complexed with metal salts forming double sulfides
Complex salts of inorganic bases fall under heading 2842 per Chapter notes.
If stabilized with organic dispersants exceeding minor amounts
Organic-inorganic mixtures not purely chemically defined shift to chemical preparations.
