European Union Deforestation Regulation (EUDR)

The EUDR introduces mandatory due diligence and traceability requirements for certain commodities and products placed on or exported from the European Union market. The Regulation will apply from 30 December 2026 for large and medium-sized companies and from 30 June 2027 for micro and small enterprises. Additional information is available on the European Commission website: EU Deforestation-Free Products Regulation. 

As a company operating within impacted supply chains, Solenis is actively preparing to meet these requirements. Achieving compliance will require close collaboration across the value chain and the timely sharing of relevant information by suppliers.

To support its EUDR compliance program, Solenis has selected Osapiens as its platform for supplier due diligence and data collection activities.

To prepare for this process, please attend the Osapiens Supplier Onboarding webinar to familiarize yourself with the Osapiens Supplier Portal and upcoming requirements:

We appreciate the important role our suppliers play in our success. By working together, we can strengthen supply chain resilience, advance responsible practices and create long-term value for customers, communities and other stakeholders.
