A registrant submitted an individual registration and ECHA requested that they update their dossier. Can the individual registrant perform the update without creating/joining a joint submission?

如果同一物质存在联合提交，您需要加入联合提交才能提交更新。如果没有联合提交，但同一物质存在个人注册人，则您应该创建联合提交，并在提交更新之前担任牵头注册人。如果没有联合提交，而您是唯一的个人注册人，则可以在不创建联合提交的情况下更新您的注册。如果请求的更新与技术完整性检查 (TCC) 失败有关，则以上情况均不适用。在这种情况下，您应该以个人注册人的身份提交更新。

If there is a joint submission for the same substance you will need join the joint submission in order to submit the update. If there is no joint submission, but there are individual registrants for the same substance, you should create a joint submission and take up the role as lead registrant before submitting the update. If there is no joint submission and you are the only individual registrant, you can update your registration without creating the joint submission. None of the above applies, if the update requested is linked to a technical completeness check (TCC) failure. In this case you should submit an update as individual registrant.
