# §180.657. Metaflumizone; tolerances for residues.

- (a) **General.**
  - (1) Tolerances are established for residues of the insecticide metaflumizone, including its metabolites and degradates, in or on the commodities listed in table 1 to this [paragraph (a)(1)](#a-1). Compliance with the tolerance levels specified in this [paragraph (a)(1)](#a-1) is to be determined by measuring only the sum of metaflumizone (E and Z isomers; 2-[2-(4-cyanophenyl)-1-[3-(trifluoromethyl) phenyl]ethylidene]-N-[4-(trifluoromethoxy)phenyl] hydrazinecarboxamide) and its metabolite 4-{2-oxo-2-[3-(trifluoromethyl) phenyl]ethyl}-benzonitrile, calculated as the stoichiometric equivalent of metaflumizone, in or on the following commodities:
  - (2) Tolerances are established for residues of the insecticide metaflumizone, including its metabolites and degradates, in or on the commodities listed in table 2 to this [paragraph (a)(2)](#a-2). Compliance with the tolerance levels specified in this [paragraph (a)(2)](#a-2) is to be determined by measuring only metaflumizone (E and Z isomers; 2-[2-(4-cyanophenyl)-1-[3-(trifluoromethyl) phenyl]ethylidene]-N-[4-(trifluoromethoxy)phenyl] hydrazinecarboxamide) in or on the following animal commodities:
- (b) **Section 18 emergency exemptions.** [Reserved]
- (c) **Tolerances with regional registrations.** [Reserved]
- (d) **Indirect or inadvertent residues.** [Reserved]
