进口商是否有义务提交混合物中进口物质的杂质/添加剂的信息，以履行 CLP 第 40（1）条规定的通知义务？

Are importers obliged to submit information on the impurities/additives of an imported substance in a mixture to fulfil the notification obligation under Article 40 (1) of CLP?

不是。如果某种物质存在于混合物中，而进口商不知道该物质是作为物质本身添加的，还是混合物中某种物质的成分（添加剂/杂质），则如果该成分符合CLP第39条的标准，则必须进行通报。但是，如果混合物的进口商掌握信息，知道混合物中存在的某种物质是混合物中另一种物质的成分（添加剂/杂质），则可以填写杂质和添加剂的字段。

No, they are not. When a substance is present in a mixture, and the importer does not know whether it has been added as a substance as such or whether it is a constituent (additive/impurity) of a substance in the mixture, then that component must be notified if it meets the criteria in Article 39 of CLP. However, when the importer of a mixture has information that a substance present in the mixture is a constituent (additive/impurity) of another substance in the mixture, then the fields on impurities and additives can be filled in.
