Recently, our company REACH24h was notified by ECHA regarding the substances which REACH24H is the lead registrant on behalf of our Non-EU clients. The communication letter detailed that for registrants of the same substance, joint submission obligation has been breached since ECHA received submission of separate registrations for the same substance. All registrants that violate the rule are required to jointly submit the required information of the substance within a limited period. If not, ECHA will revoke their registration number and reject the registration.
