Haloxyfop-P-butyl Technical Grade
Haloxyfop-P-butyl, chemically Butyl (R)-2-[4-(5-trifluoromethyl-2-pyridinyloxy)phenoxy]propanoate, is a selective graminicide active ingredient used in herbicide formulations. It falls under HTS 2933.99.0100 due to its specific heterocyclic structure with pyridine nitrogen hetero-atom in aromatic form. Produced at 95-98% purity for agrochemical manufacturing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If enantiomeric purity <95% or contains impurities altering definition
Impure or non-chiral versions classify as other aromatic nitrogen heterocycles under the chapter's residual provision.
If supplied as solution in solvent for safety/transport
Solutions of chapter 29 compounds in solvents for transport fall under 3824 if not constituting normal pure form per chapter note 2(e).
If classified primarily by aryloxypropanoic acid structure ignoring heterocycle
Alternative view as ether derivatives of phenols, but chapter 29 note prioritizes heterocyclic heading last in numerical order.
