牵头注册人的吨位范围可以低于联合提交的吨位范围吗？

Can the tonnage band of the lead registrant be below the Joint Submission tonnage band?

是的。如果牵头注册人希望将其吨位级别降低至联合提交的吨位级别以下，则牵头注册人需要提交自发更新。步骤1：IUCLID 工作环境中指示的吨位级别代表联合提交的吨位级别，应与上次成功提交时使用的吨位级别保持一致。步骤2：在档案中填写相关数据后，注册人必须点击“创建档案”。步骤3：档案标题中指示的吨位级别代表牵头注册人自身注册的吨位级别，可以等于或低于联合提交的吨位级别。步骤4：将档案标记为更新，添加上次成功提交的编号，并从下拉菜单中选择“更改自身吨位级别”作为自发更新的理由。

Yes. If the lead registrant wants to lower his tonnage band below the tonnage band of the Joint Submission, the Lead needs to submit a spontaneous update.Step 1The tonnage band indicated in the IUCLID working context represents the tonnage band of the Joint Submission and should remain the same as used during the last successful submission. Step 2After filling in the dossier with the relevant data, the registrant must click on “Create dossier”. Step 3The tonnage band to be indicated in the dossier header represents the tonnage band of the Lead Registrant’s own registration, which can be equal or lower than the tonnage band of the Joint Submission. Step 4Mark the dossier as an update, add the last successful submission number and chose ‘change of own tonnage band’ from the drop-down menu as justification for the spontaneous update.
