Aluminum in Pesticide Formulations; Exemption From the Requirement for a Tolerance

Document 2026-10267 is a Final Rule published by the Environmental Protection Agency in the Federal Register on May 22, 2026, with an effective date of May 22, 2026. This regulation establishes an exemption from the requirement of a tolerance for residues of aluminum (CAS Reg. No. 7429-90-5) when used as an inert ingredient (seed treatment colorant) for seed treatment only at not more than 5% of pesticide formulation. Steptoe & Johnson, LLP on behalf of Sun Chemical, 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 aluminum, when used in accordance with the terms of those exemptions.
