## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of tin oxide (CAS Reg. No. 18282-10-5) when used as an inert ingredient (seed treatment colorant) not to exceed 40% by weight in pesticide formulations applied to growing crops. Exponent on behalf of Aceto Corporation submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of tin oxide.
