This regulation establishes an exemption from the requirement of a tolerance for residues of diglycerol when used as an inert ingredient (plasticizer) on growing crops and raw agricultural commodities pre- and post-harvest. This regulation eliminates the need to establish a maximum permissible level for residues of diglycerol, when used in accordance with the terms of the exemption. This regulation also amends the tolerance exemption 2,6-pyridinedicarboxylic acid by correcting the CAS Reg. No.
