答案（中文）
是的。CLP 第 17 条 (1) 款 (a) 项规定，标签上必须包含供应商的名称、地址和电话号码。此外，根据第 4 条 (4) 项规定，供应商必须确保危险物质或混合物在投放市场前按照 CLP 法规第三章和第四章的规定进行标记和包装。原则上，供应链中可以同时存在同一种危险物质或混合物的多个供应商。例如，当危险物质或含有危险物质的混合物供应给分销商，分销商再将其供应给第三方时，就可能出现这种情况。如果分销商随后更改包装，导致 CLP 第 17 条规定的标签要素必须以与原始标签/包装不同的方式显示，则应添加分销商的联系方式或替换先前供应商的联系方式。在这种情况下，分销商承担了重新包装和重新标记物质或混合物的责任。如果分销商不更改包装或标签，则无需在标签上添加其联系方式，也无需替换其供应商的联系方式。但是，分销商可以根据自己的意愿进行更改。当供应商更改标签上显示的语言时，他们有责任确保标签内容的正确翻译。因此，他们应将其联系方式添加到签发原始标签的供应商的联系方式中。
Answer (EN)
Yes they are. CLP Article 17 (1) (a) states that the name, address and telephone number of the supplier(s) must be included on the label. Furthermore, as stated in Article 4 (4), a supplier must ensure that a hazardous substance or mixture is labelled and packaged in accordance with Titles III and IV of the CLP Regulation, before placing it on the market.
In principle, there can be more than one supplier of the same hazardous substance or mixture in the supply chain at the same time. This can be the case, for example, when a hazardous substance or a mixture containing hazardous substances has been supplied to a distributor, who then supplies it to third parties. If the distributor then changes the packaging to such an extent that the label elements set out in CLP Article 17 have to be displayed differently than on the original label/packaging supplied, then the contact details of the distributor should be added to or replace the contact information of the previous supplier. In this scenario, the distributor has taken on the responsibility for repackaging and re-labelling of the substance or mixture.
If distributors do not change the packaging or labelling, then they do not need to add their contact details to the label nor replace the contact information of their supplier. The distributors may however do so if they wish to.
When a supplier changes the languages(s) displayed on a label, they become responsible for the correct translation of the label content. Thus, they should add their contact details to the contact details of the supplier who issued the original label.
