🇬🇧 English

This rule allows aluminum to be used as an inert colorant in pesticide products for seed treatment without setting a maximum residue limit, as long as it is used only for seed treatment and does not exceed 5% of the pesticide formulation. The change mainly affects pesticide manufacturers, seed treatment businesses, agricultural producers, and food manufacturers. Companies using aluminum in this narrow way gain a clearer compliance path, but they must stay within the 5% formulation limit and the seed-treatment-only use.
