主注册人更新该物质所有注册人的档案，并表明他们确认档案中的数据。在这种情况下，此确认信息是否应填写在 IUCLID 档案的备注栏中？还是每个注册人都应该更新自己的档案？或者每个注册人都应该回复 ECHA 的信函？

The lead registrant updates the dossier for all registrants of the substance and indicates that they confirm the data of the dossier. In this case, should this confirmation be filled in a remark field of the IUCLID dossier? Or should each registrant update its own dossier? Or should each registrant answer to ECHA’s letter?

仅当需要包含新的/修订的信息时，注册更新才有意义。如果您注册中的信息正确无误，则无需更新档案或回复收到的信函。如果相关的新的/修订信息需要包含在联合提交的档案中，且该新的/修订信息对所有注册人均有效，则由主注册人进行更新即可。但是，如果更新档案中包含的新的/修订信息是成员特有的（例如，有关物质成分或特定用途的信息），则可能只有某些成员需要更新其档案。

Registration updates are only relevant if new/revised information is to be included. If the information in your registration is correct, you do not need to update your dossier or respond to the letter you received. If relevant new/revised information is to be included in a dossier submitted jointly, an update by the lead registrant is sufficient if this new/revised information is valid for all registrants. However, if the new/revised information to be included in a dossier updated is members’ specific (e.g. information on substance composition or on specific uses) then it could be that only certain members need to update their dossiers.
