40 CFR § 180.473 - Glufosinate; tolerances for residues.
(a) General. Tolerances are established for residues of glufosinate, including its metabolites and degradates, in or on the commodities in the following table. Compliance with the tolerance levels specified in the following table is to be determined by measuring the sum of glufosinate (2-amino-4-(hydroxymethylphosphinyl)butanoic acid) and its metabolites, 2-(acetylamino)-4-(hydroxymethyl phosphinyl) butanoic acid, and 3-(hydroxymethylphosphinyl) propanoic acid, expressed as 2-amino-4-(hydroxymethylphosphinyl)butanoic acid equivalents.

(c) Tolerances with regional registrations. Tolerances with regional registrations are established for residues of glufosinate, including its metabolites and degradates, in or on the commodities in the following table. Compliance with the tolerance levels specified in the following table is to be determined by measuring the sum of glufosinate, (2-amino-4-(hydroxymethylphosphinyl)butanoic acid) and its metabolites, 2-(acetylamino)-4-(hydroxymethyl phosphinyl) butanoic acid, and 3-(hydroxymethylphosphinyl) propanoic acid, expressed as 2-amino-4-(hydroxymethylphosphinyl)butanoic acid equivalents.

(d) Indirect or inadvertent residues. Tolerances are established for indirect or inadvertent residues of glufosinate, including its metabolites and degradates, in or on the commodities in the following table, as a result of the application of glufosinate to crops listed in paragraph (a) of this section. Compliance with the tolerance levels specified in the following table is to be determined by measuring the sum of glufosinate (2-amino-4-(hydroxymethylphosphinyl) butanoic acid) and its metabolite, 3-(hydroxymethylphosphinyl) propanoic acid, expressed as 2-amino-4-(hydroxymethylphosphinyl)butanoic acid equivalents.
