答案（中文）
是的。在C&L名录中，同一种物质的不同分类可能有不同的原因，例如不同的杂质概况。在其他情况下，由于在评估现有数据的过程中或在应用CLP分类规则时存在解释差异，通知人或注册人可能对同一种物质得出不同的分类。但是，CLP第41条要求通知人和注册人尽一切努力就同一种物质达成一致的条目，除非能够提供偏离分类的合理性（例如杂质概况）。
Answer (EN)
Yes, it is. On the C&L Inventory differing classifications for the same substance can have different reasons, e.g. different impurity profiles. In other cases, notifiers or registrants may have reached a different classification for the same substance due to interpretation differences in the process of evaluation of available data or in the application of the classification rules for CLP.
However, Article 41 of CLP requires notifiers and registrants to make every effort to come to an agreed entry for the same substance, unless a justification (e.g. impurity profile) can be provided for deviating classifications.
