New legal regulations on nanoforms of substances in the context of the legal certainty principle

New legal regulations concerning nanomaterials in the scope of the legal certainty principle were discussed. Commission Regulation (EU) 2018/1881 of 03/12/2018 amending the REACH regulation with regard to Annexes I, III, VI-XII is the first normative act on chemicals that sets out the requirements for the registration of nanoforms of substances. The new requirements for nanomaterials will serve to implement the principle of legal certainty in this area. The presented analysis of the introduced amendments to the annexes to the REACH regulation indicates some shortcomings of the new legal regulations.
