CE mark Biostimulants

Providing the world CE marked Biostimulants!

During the summer we have worked very hard on getting our Biostimulants, both microbial and non-microbial certified by KIWA VERIN for the CE mark under the new Fertilizer Regulation 2019/1009 (FPR).


In December we received the wonderful news that our products met the strict quality and safety standards of the FPR and we got certified for all of our Biostimulants. We are very proud that we are now able to carry the CE mark on our products. It proofs that our products fully comply to all the requirements of the FPR which gives again an extra quality assurance to you as a customer. It also gives you the certainty our products are free to be used in every European Member state.


It is the first time Biostimulants are able to be assessed for CE marking. This has all been made possible by the new Fertilizer Regulation which went into force on the 16th of July this year. In the new FPR they have included Biostimulants which means products listed in this category can be assessed for a the modules to get certified for a CE mark.


A CE marking indicates that a product has been assessed by a notifying body and therefore meets the EU safety, health and environmental protection requirements all set out in the corresponding Regulation.
