Our company


tier3 solutions is an independent and privately owned GLP-certified contract research organization (CRO). 

Our mission is to make chemicals safe according to international environmental safety guidelines by supporting our clients with high-quality scientific and regulatory expertise. 

Our in-house services include:

  • Conducting field studies required for the registration and approval of plant protection products (PPPs). 
  • Supporting our clients during the registration process, including the preparation of EU Dossiers (Environmental Fate and Ecotoxicology), provision of comprehensive risk assessments for PPPs and active substances as well as post-submission support.

To date, we have conducted over 70 GLP field studies (and more than 100 field studies in total) in several  EU countries for many different clients. 

Our work on many hundreds of pesticide dossiers has enabled us to gain broad expertise on possible refinement steps in the environmental risk assessment. 

Please contact us to discuss your requirements.
