根据 REACH 第 17(2) 条或第 18(2) 条，分离中间体的注册是否需要因吨位范围变化而更新？

Does a registration of an isolated intermediate pursuant to Article 17(2) or Article 18(2) of REACH have to be updated due to a change of tonnage band?

根据 REACH 第 17(2) 条或第 18(2) 条注册了分离中间体的生产商或进口商，通常无需在吨位级别变更时更新注册。然而，在两种情况下，由于吨位级别变更，此类注册必须更新。情况 1：如果注册的是运输用分离中间体，并且达到了 1000 吨/年的门槛，则注册人必须更新其注册档案，提交 REACH 法规附件 VII 中规定的信息（如果尚未包含在档案中）。情况 2：如果注册人停止生产和进口分离中间体，则他有问答 54 中描述的义务，其中包括更新注册。

A manufacturer or importer who has registered an isolated intermediate pursuant to Article 17(2) or Article 18(2) of REACH does in general not have to update this registration in case of a change of tonnage band. However, such a registration would have to be updated due to a change of tonnage band in two cases.   Case 1: Where the registration is for a transported isolated intermediate and the 1000 t/a threshold is reached, the registrant must update his registration dossier by submitting the information specified in Annex VII of the REACH Regulation, if not already included in the dossier.   Case 2: Where the registrant ceases manufacture and import of the isolated intermediate, he has the duties described in Q&A 54, which include an update of the registration.
