当欧盟进口商从已指定唯一代表的非欧盟制造商进口某种物质时，欧盟进口商是否可以注册从该非欧盟制造商进口的部分数量，并依靠唯一代表的注册来进口剩余数量？

When an EU importer imports a substance from a non-EU manufacturer that has appointed an only representative, can the EU importer register part of the volumes they import from that non-EU manufacturer and rely on the registration of the only representative for the remaining volumes?

不可以，进口商不能。在同一供应链中，欧盟进口商不能将其进口量拆分给唯一代表注册和自身注册。事实上，REACH法规规定的义务不能通过将进口量分配给不同参与者来规避，因为分配给每个参与者的数量低于注册义务的门槛值或要求提供更全面信息的门槛值之一。因此，进口商从非欧盟制造商进口的所有数量的物质都必须包含在同一份注册中。但是，进口商可以决定是否希望其注册义务由非欧盟制造商指定的唯一代表履行，还是由其作为进口商履行。

No, the importer cannot. In the same supply chain, the EU importer cannot split the volumes they import between an only representative registration and their own registration.Indeed, obligations arising from the REACH Regulation cannot be circumvented by distributing the imported volumes between different actors, such that the quantity thus allocated to each of them is below the threshold of the registration obligation or one of the thresholds requiring the provision of more comprehensive information. As a result, all quantities of the substance an importer imports from a non-EU manufacturer must be covered by the same registration. An importer may however decide whether they want their registration obligation to be fulfilled by the only representative appointed by the non-EU manufacturer or by themselves as an importer.
