Ethyl (R)-Quizalofop Technical Grade
The R-enantiomer of 2-[4-[(6-chloroquinoxalin-2-yl)oxy]phenoxy]propanoic acid ethyl ester, known as (R)-quizalofop-ethyl, is a high-purity chiral herbicide active ingredient. Classified under HTS 2933.99.0200 due to its specific named heterocyclic structure with nitrogen-only heteroatoms in the aromatic quinoxaline ring. Used in enantiopure formulations for enhanced selectivity in soybean and cotton weed control.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the quinoxaline ring is considered non-aromatic
Non-aromatic heterocyclic compounds with N hetero-atoms classify under 2933.39 rather than aromatic 2933.99.
If for insecticide formulations despite primary herbicide use
If labeled or principally used as insecticide, shifts to specific pesticide subheading in Chapter 38.
If imported as ethyl ester without full heterocyclic specification
Ether-alcohol derivatives might classify under 2909 if the heterocyclic principal function is not dominant.

Import Tips & Compliance
• Verify enantiomeric purity via HPLC analysis for customs; include TSCA certification if for non-pesticide R&D; watch for quota restrictions on agrochemicals
