# §180.723. Spiropidion; tolerances for residues.

- (a) **General.**
  - (1) Tolerances are established for residues of the insecticide spiropidion, including its metabolites and degradates, in or on the commodities in Table 1 to this [paragraph (a)(1)](#a-1). Compliance with the tolerance levels specified in Table 1 to this [paragraph (a)(1)](#a-1) is to be determined by measuring only the sum of spiropidion [3-(4-chloro-2,6-dimethyl-phenyl)-8-methoxy-1-methyl-2-oxo-1,8-diazaspiro[4.5]dec-3-en-4-yl ethyl carbonate] and its metabolite SYN547305 [3-(4-chloro-2,6-dimethylphenyl)-4-hydroxy-8-methoxy-1-methyl-1,8-diazaspiro[4.5]dec-3-en-2-one] calculated as the stoichiometric equivalent of spiropidion, in or on the following plant commodities:
  - (2) Tolerances are established for residues of the insecticide spiropidion, including its metabolites and degradates, in or on the commodities in Table 2 to this [paragraph (a)(2)](#a-2). Compliance with the tolerance levels specified in Table 2 to this [paragraph (a)(2)](#a-2) is to be determined by measuring only SYN547305 [3-(4-chloro-2,6-dimethylphenyl)-4-hydroxy-8-methoxy-1-methyl-1,8-diazaspiro[4.5]dec-3-en-2-one] calculated as the stoichiometric equivalent of spiropidion, in or on the following livestock commodities:
