在将某种物质通报至分类和标签清单时，其成分、添加剂和杂质是否也需要单独通报？

When notifying a substance to the Classification and Labelling Inventory, do its constituents, additives and impurities also have to be notified separately?

不，不需要。物质的成分、添加剂和杂质无需单独通报，即使它们具有危险性并有助于物质的分类。这是因为根据 CLP 第 2(7) 条，它们已包含在物质的定义中：“物质”是指自然状态或通过任何制造工艺获得的化学元素及其化合物，包括为保持其稳定性所必需的任何添加剂和任何源自工艺的杂质，但不包括任何可在不影响物质稳定性或改变其成分的情况下分离的溶剂。但是，如果这些杂质、添加剂或成分也作为单独的物质销售，则当然必须进行通报。IUCLID 6 允许指示为保持物质稳定性所必需的任何杂质和添加剂的存在情况，以及它们对第 1.2 节中通报物质分类的贡献。

No, they do not. Constituents, additives and impurities of a substance do not need to be notified individually, even if they are hazardous and contribute to the classification of the substance. This is because they are included in the definition of a substance, pursuant to CLP Article 2(7): 'substance' means a chemical element and its compounds in the natural state or obtained by any manufacturing process, including any additive necessary to preserve its stability and any impurity deriving from the process used, but excluding any solvent which may be separated without affecting the stability of the substance or changing its composition. However, if these impurities, additives or constituents are also marketed as separate substances, these will of course have to be notified.   IUCLID 6 allows the indication of the presence of any impurities and additives necessary to preserve the stability of a substance as well as their contribution to a classification of the notified substance in section 1.2.
