REACH第V篇（第37至39条）规定，下游用户有义务将物质的用途告知其供应商。供应商必须对物质用途进行评估，并就能否支持将此用途作为确认用途向下游用户反馈信息。如果不支持将此用途作为确认用途，下游用户可有多种选项继续使用此物质。下游用户与供应商之间的信息传递必须在具体的最后期限完成。 另外，在特定条件下，下游用户还有向欧洲化学品管理局报告信息的义务。 

In REACH Title V (Art. 37 to 39) the DU has the right  to make his use known to his suppliers. The supplier  has the duty to evaluate the use and to provide  information back to the DU on whether or not the use  can be supported as an identified use. If the use is not supported, the DU has several options to continue using the substance. Certain deadlines have to be respected for the communications between DU and supplier.  In addition, there are also obligations for DUs to report  information to ECHA under special conditions.

欧洲化学品管理局的”下游用户指南” 可为所有的职责提供帮助。 指南文件中的表5概述了与不同角色相关的义务。 欧洲化学品管理局下游用户指南第3与4章就下游用户如何应对REACH及下游用户收到新信息后该如何处理提供了建议。 

The ECHA“Guidance for downstream users”provides assistance with all tasks. Table 5 of the guidance document provides an overview in regard to possible obligations related to different roles. In Chapters 3 and 4 of the guidance document, recommendations are given on how a DU can prepare  for REACH and what is to be done when a DU receives  new information.

注： 

REACH第V篇规定的所有义务限于符合 CLP 法规危险物质标准的物质或配制品中的物质。更多信息，请参见REACH第V篇。

NOTE：

All obligations under Title V of REACH are limited to substances or substances in mixtures which are  hazardous according to CLP. Refer to Title V of REACH  for more information.

为了保证危险单独物质或配制品中的物质的持续供应，下游用户必须确认供应商是否将其添加到物质注册卷宗中以支持他们的物质用途。 

In order to secure a continued supply of a hazardous  substance on its own or in a mixture a DU has to check  whether the supplier will support their use(s) by  including them in the substance registration dossier.

不允许下游用户使用在支持用途范围以外的物质。如果下游用户不确定其供应商是否了解其物质用途，下游用户应尽早向供应商进行信息传递，以保证其物质用途包括在供应商的注册卷宗中。 

Any use of a registered substance by a DU outside the  supported uses is not allowed. If DUs are not sure if  their supplier is aware of their use, it is in the interest of DUs to communicate early with suppliers with the view of having their use(s) included in the supplier’s  registration dossier.

对于年使用量超过10吨的有害物质，通过扩展安全数据表中的暴露状况进行支持用途信息传递。扩展安全数据表将在注册者实施注册后发布。注册的最后期限取决于物质的有害等级及制造商或进口商的制造量或进口量。对于每年制造量或使用量为1–10吨的有害物质，其用途通过只包括一般使用类别的标准安全数据表进行传递。 5.5 REACH第V篇规定的下游用户的义务

For hazardous substances >10 tpa, the supported uses are communicated through the ES in the Ext-SDS. Such Ext-SDS will be issued once the registrant has made his registration. The registration deadline depends on the  hazard classification of the substance and its volume  per manufacturer/importer. For hazardous substances  between 1-10 tpa the use is communicated via a basic  SDS where only general use categories are included.

注：

REACH包括两种不同的确认用途传递方式： 

» 对于每年1–10吨的有害物质：包括一般使用类别的安全数据表（仅简单信息） 

» 对于每年超过10吨的有害物质：包括说明信息的扩展安全数据表（详细信息） 

NOTE：

There are two different ways to communicate identified uses under REACH: 

» For hazardous substances between 1-10 tpa:  SDS including general use categories (only reduced information) 

» For hazardous substances > 10tpa: Ext-SDS including Use Descriptors (detailed information)

非有害物质或无有害成分的配制品无需安全数据表，因此没有使用限制。在这种情况下无需向下游用户提供暴露状况。

Non-hazardous substances or mixtures without  hazardous ingredients do not require an SDS and therefore have no use restrictions. In this case an ES is  not provided to the DU.
