Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If aromatic ether intermediates
Diphenyl ether function may classify earlier if pesticide identity not declared.
If mixed active ingredient formulations
Goods containing multiple fungicide AIs classify as mixtures in Chapter 38.
If oxygen heterocyclic dominance
Oxygen bridge compounds could shift to 2932 unless triazole pesticide prevails.
