在对 CLP 法规附件 VI 中包含的物质进行分类和标记时，我是否需要考虑可能与 CLP 第 11(1) 条规定的分类相关的任何杂质？

When classifying and labelling substances that are included in Annex VI to the CLP Regulation, do I need to consider any impurities that might be relevant to classification as stipulated in Article 11(1) CLP?

是的，需要。根据 CLP 法规附件 VI 第 1.1.1.4 节的规定，除非杂质对物质的分类有重大影响，否则 CLP 附件 VI 中的条目通常不会提及杂质。这意味着 CLP 附件 VI 中的条目通常与“纯”物质的毒性有关，而杂质并未被考虑在内。因此，如果投放市场的物质含有 CLP 附件 VI 相应条目中未指定的杂质，则必须根据 CLP 第 11(1) 条的规定，将已分类杂质的存在纳入分类范围。

Yes, you do. As stated in section 1.1.1.4 of Annex VI to the CLP Regulation, impurities are not normally mentioned in Annex VI to CLP entries unless they contribute significantly to the classification of the substance. This means that the entry in Annex VI to CLP relates normally to the toxicity of the "pure" substance and impurities have not been taken into account. Therefore, if the substance placed on the market contains an impurity not specified in the corresponding entry in Annex VI to CLP, the presence of classified impurities must be taken into account for classification purposes in accordance with Article 11(1) CLP.
