In EU, application of technical equivalence (TE) assessment is the easiest way to gain market access for your pesticide technical materials or active substances. If the new source (i.e., your product) has the same or less harmful effects due to its impurities compared to the reference source of an approved technical material, then the new source can be considered (eco)toxicologically equivalent to the reference source. Once the TE application is approved, you can sell your technical materials to all EU Member States.
