H4R REACH Consortium
Hydrocarbon Resins, Rosin Resins and Pine Chemicals Materials REACH (H4R)
About H4R REACH Consortium
Ensuring safe, compliant, and sustainable market access for Hydrocarbon, Rosin, and Resins.
The H4R REACH Consortium brings together manufacturers and importers of Hydrocarbon Resins, Rosin Resins, and Pine Chemicals Materials to ensure compliance with the EU REACH Regulation. Registration is mandatory for any company producing or importing one tonne or more of these substances per year within the EEA, protecting both public health and the environment.
Since its launch in October 2008, the H4R Consortium has successfully coordinated the registration of 28 substances prior to the 2010 REACH deadline and continues to maintain dossier compliance with REACH and CLP for its members, ensuring safe market access and mitigating legal and financial risk.
