供应商是否必须在相应的技术进步适应性规定 (ATP) 中指明的申请日期之前遵守 CLP 附件 VI 中物质的协调分类和标签 (C&L)？

Do suppliers have to comply with the harmonised classification and labelling (C&L) of a substance in Annex VI to CLP before the application date indicated in the respective adaptation to technical progress (ATP)?

CLP 附件 VI 中所列物质的新的或修订的协调 C&L 必须从相应 ATP 中指定的日期开始应用，但供应商可以在该日期之前使用此分类。如果供应商决定不在此日期之前应用某种物质的协调 C&L，那么就会出现一个问题，即他们是否仍应在物质或混合物的自我分类中考虑 ECHA 风险评估委员会 (RAC) 对该物质协调 C&L 的意见。当供应商在将其物质或混合物投放市场之前考虑其自我分类时（CLP 第 4(1) 条），他们必须识别和检查所有可用信息（CLP 第 5 条）。分类必须反映最新的科学知识（CLP 第 5(1)(d) 和第 15 条）。在遵守物质新的协调 C&L 的过渡期内，RAC 对该物质的意见应被视为最新的可靠科学证据，并应反映在物质或混合物的自我分类中，除非供应商有与 RAC 意见不同的其他科学证据并得出不同的结论。如果某种物质的 C&L 已经在同一危险类别中协调，则在 ATP 中正式更改为 CLP 之前，必须依法遵守现有的协调 C&L。新的协调 C&L 可在相应的 ATP 生效后立即自愿适用。在适用之日，根据相应的 ATP 规定，供应商有义务遵守新的 C&L。

A new or revised harmonised C&L of a substance set out in Annex VI to CLP must be applied from the date specified in the respective ATP, although suppliers may use this classification before that date. In cases where a supplier decides not to apply the harmonised C&L of a substance before this date, the question arises whether they should nevertheless take into consideration the opinion adopted by the ECHA Risk Assessment Committee (RAC) on the harmonised C&L for that substance in the self-classification of a substance or mixture. When suppliers consider the self-classification of their substance or mixture before placing them on the market (Article 4(1) of CLP), they must identify and examine all available information (Article 5 of CLP). The classification must reflect the latest scientific knowledge (Articles 5(1)(d) and 15 of CLP). During the transitional period for compliance with a new harmonised C&L for a substance, the RAC opinion for that substance should be considered as the latest reliable scientific evidence that should be reflected in the self-classification of the substance or mixture, unless the supplier has other scientific evidence that differs from the RAC opinion and leads to a different conclusion. If the C&L of a substance is already harmonised in the same hazard class, compliance with the existing harmonised C&L is legally required until it is formally changed in an ATP to CLP. The new harmonised C&L may be voluntarily applied as soon as the respective ATP enters into force. At the date of applicability, as provided for in the respective ATP, the suppliers are obliged to comply with the new C&L.
