As 2021 begins, new safety data sheet (SDS) requirements in the European Union (EU) will enter into force. Commission Regulation (EU) 2020/878 of June 18, 2020, amends Annex II to Regulation (EC) No 1907/2006 on the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH). The requirements for SDS layout and content appear in REACH, while the hazard classification criteria and labeling requirements are derivative of Regulation (EC) No 1272/2008 on the Classification, Labeling, and Packaging of Substances and Mixtures (CLP). The changes to the regulation apply starting January 1, 2021, with certain provisions in Article 2 that note that noncompliant SDSs may continue until December 31, 2022.
