Compliance Check
Definition
A Compliance Check is a formal ECHA evaluation process under REACH Article 41 to verify whether the information in a registration dossier complies with the information requirements of Annexes VII–X. ECHA selects dossiers for compliance checks based on risk-based criteria. If the dossier is found to be incomplete or inaccurate, ECHA issues a Decision requiring the registrant to submit additional information within a defined timeline. ECHA has progressively increased the rate of compliance checking since 2013.

Practical Explanation (Compliance Context)
Registrants must be prepared to respond to ECHA Compliance Check decisions within the deadlines specified. Non-response or inadequate response can result in further enforcement action. Maintaining up-to-date, scientifically robust registration dossiers — including current study summaries, classification data, and exposure scenarios — is the best defence against compliance check action.
