我是附件 XIV 物质的下游用户，欧盟委员会尚未就我供应链上游一家公司提交的涵盖我用途的授权申请做出决定。该物质的失效日期已过。 a) 我必须停止使用该物质吗？ b) 我必须向欧洲化学品管理局 (ECHA) 申报我的用途吗？

我是附件 XIV 物质的下游用户，欧盟委员会尚未就我供应链上游一家公司提交的涵盖我用途的授权申请做出决定。该物质的失效日期已过。 a) 我必须停止使用该物质吗？ b) 我必须向欧洲化学品管理局 (ECHA) 申报我的用途吗？

I am a downstream user of an Annex XIV substance and the European Commission has not yet decided on the application for authorisation submitted by a company up my supply chain covering my use. The sunset date of the substance has passed. a) Do I have to stop using the substance? b) Do I have to notify my use to ECHA?

a) 视情况而定。如果构成您供应链的申请是在物质的最新申请日期之前提交的，您无需停止。在这种情况下，您可以在日落日期之后继续使用该物质，等待欧盟委员会的决定。如果授权申请是在物质的最新申请日期之后提交的，则必须停止。只有欧盟委员会决定授权您的使用，您才能重新开始使用该物质。b) 还没有。只要欧盟委员会尚未就涵盖您用途的授权申请做出决定，您就无法向 ECHA 通知您的用途。只有在获得授权后才能通知授权用途。一旦批准授权的决定被采纳，您需要在首次交付该物质后三个月内向 ECHA 提交授权用途的下游用户通知（REACH 第 66 条）（另见问答 1441）。

a) It depends. You do not have to stop if the application made up your supply chain has been submitted before the substance’s latest application date. In this case, you can continue using the substance after its sunset date, awaiting for the European Commission’s decision. You have to stop if the authorisation application has been submitted after the substance’s latest application date. You can restart using the substance only if the European Commission decides to grant an authorisation for your use.  b) Not yet. As long as the European Commission’s decision on the authorisation application covering your use is pending, you cannot notify your use to ECHA. The notification of authorised uses is possible only after an authorisation has been granted. Once the decision to grant an authorisation has been adopted, you then need to submit a downstream user notification of your authorised use (Article 66 of REACH) to ECHA within three months from the first delivery of the substance (see also Q&A 1441).
