ECHA reports on the progress made in 2023 in dossier and substance evaluation in line with Article 54 of REACH. 

Progress in compliance checks

In 2023 ECHA continued its work on screening structurally similar substances in groups: as in the previous years, ECHA started looking at around 2 000 substances. Based on the group assessments of regulatory needs, in 2023 ECHA has selected 248 substances representing 33 groups for compliance check.

Important hazard data have been requested to clarify concerns related to human health and environmental hazards, including those affecting reproduction and causing genetic mutations.

In 2023, ECHA carried out 301 full compliance checks covering more than 1750 dossiers and 274 unique substances. The full checks focused on addressing relevant higher-tier hazard endpoints for substances or groups of substances of potential concern mainly in the higher tonnage bands. In addition, ECHA conducted 95 targeted compliance checks, which together with the full checks resulted in a total of 396 compliance checks performed in 2023, covering over 2000 registration dossiers, and addressing 329 unique substances.

The Agency continued in 2023 checking compliance of those dossiers where registrants opted out from the joint submission and instead submitted their information separately. Checking these dossiers contributes to ensuring a level playing field and supports the functioning of the internal market. The Agency checked compliance for 23 dossiers covering 17 substances submitted by companies opting out from joint submissions. Consequently, 18 draft decisions were sent for 13 substances.

Outputs of dossier assessments in 2023

ECHA performed 301 full compliance checks (CCHs) and 104 testing proposal examinations (TPEs), covering 367 unique substances. The selection of registrations for compliance check was mainly based on (groups of) substances raising potential hazard- or exposure-based concerns.

ECHA issued 367 decisions: 251 on the compliance checks (full and targeted) and 116 on testing proposal examinations.
