# §180.680. Fluensulfone; tolerances for residues.

- (a) **General.** Tolerances are established for residues of the nematicide fluensulfone, including its metabolites and degradates, in or on the commodities in the table 1 to § 180.680. Compliance with the tolerance levels specified in the following table below is to be determined by measuring only the sum of fluensulfone, 5-chloro-2-[(3,4,4-trifluoro-3-buten-1-yl)sulfonyl]thiazole and its metabolite, 3,4,4-trifluoro-but-3-ene-1-sulfonic acid, calculated as the stoichiometric equivalent of fluensulfone, in or on the commodity.
- (b) **Section 18 emergency exemptions.** [Reserved]
- (c) **Tolerances with regional registrations.** [Reserved]
- (d) **Indirect or inadvertent residues.** Tolerances are established for residues of the nematicide fluensulfone, including its metabolites and degradates, in or on the commodities in table 2 to § 180.680. Compliance with the tolerance levels specified in the following table below is to be determined by measuring only the sum of fluensulfone, 5-chloro-2-[(3,4,4-trifluoro-3-buten-1-yl)sulfonyl]thiazole and its metabolite, 3,4,4-trifluoro-but-3-ene-1-sulfonic acid, calculated as the stoichiometric equivalent of fluensulfone, in or on the commodity.
