Reach is a European Union regulation adopted in 2006 to improve chemical safety through the registration, evaluation, authorization, and restriction of chemicals. Companies must register their chemical products containing hazardous substances and receive REACH compliance certificates from certification bodies like Arcerion GmbH to prove their products meet REACH requirements and can legally be sold in the EU. Arcerion provides REACH experts and only representatives to help companies register their products and achieve full REACH compliance.
