答案（中文）
不，他们不需要。只要他们不将所供应的物质和混合物投放市场，他们就被视为其最终用户。专业用户的例子包括清洁人员、油漆工或工匠，他们在专业活动中使用油漆、石灰或清洁剂等。工业用户可能会将所供应的物质或混合物用作加工助剂，这些助剂不会被工业活动消耗，例如电镀前的表面清洁剂或链锯润滑剂的用户。混合物的配制者不被视为最终用户，而是物质和混合物的下游用户。专业和工业最终用户必须遵守标签上以及提供给他们的安全数据表 (SDS) 上的信息。此外，他们还必须遵守 REACH 法规第五章中关于安全处理和使用物质和混合物的下游用户义务。请注意，在欧盟境内设立的最终用户，如果由欧盟以外的行为者供应物质或混合物，则根据 CLP 被视为进口商。这意味着他们有义务对这些物质和混合物进行分类、标记和包装，并将相关物质信息通报给C&L清单。
Answer (EN)
No, they do not. They are considered to be end users of the substances and mixtures supplied to them as long as they do not place the substances and mixtures on the market. Examples of professional users are cleaning personnel, painters or craftsmen who use e.g. paints, lime or cleaning agents in the context of their professional activity. Industrial users may use substances or mixtures supplied to them as processing aids which are not consumed by the industrial activity, e.g. surface cleaners prior to electroplating or users of lubricants for chainsaws. Formulators of mixtures are not considered as end users, but rather as downstream users of substances and mixtures.
Professional and industrial end users are required to respect the information on the label and on the Safety Data Sheet supplied to them. Further to this, they have to comply with the downstream user obligations set out in Title V of REACH on the safe handling and use of substances and mixtures.
Note that end users established within the EU, who are supplied with substances or mixtures by an actor outside the EU, are considered to be importers under CLP. This means that they have the obligation to classify, label and package these substances and mixtures and to notify relevant substance information to the C&L Inventory.
