As per Regulation (EC) No. 1107/2009, repealing directive 91/414/EEC, 2,4,5-T is not approved for use in the European Union. But a default maximum residue limit (MRL) of 0.01 mg/kg is applicable for the presence of 2,4,5-T (taken as a sum of 2,4,5-T, its salts, and esters) in products of plant origin, in accordance with Regulation (EC) No. 2015/868.
