答案（中文）
根据 REACH 第 26 条提交问询后，作为潜在注册人，您将可以访问 REACH-IT 中的共同注册人页面，在该页面您可以找到同一物质的先前注册人的信息。根据先前注册人提供的信息，您可以找到制造商、进口商或其代表的名称、地址和其他联系方式。此时，您可能会意识到，提交您注册所需数据的先前注册人正受到欧盟制裁。这可能包括之前由受此类措施约束的非欧盟制造商的唯一代表提交数据的情况。相关制裁可能包括禁止向受制裁方提供经济资源、禁止与该方进行交易或禁止提供某些服务。根据每种情况，这些禁令可能会阻止您与先前注册人之间达成数据共享协议。如果是这种情况，作为最后的手段，您可以向欧洲化学品管理局 (ECHA) 提交数据共享争议。有关数据共享的更多详情，请参阅“数据共享 - ECHA (europa.eu)”和数据共享指南。请注意，注册人可能已指定第三方代表，向其共同注册人隐藏其姓名，或提交请求，向公众隐藏注册人的姓名。只有非欧盟制造商的代表也可能选择不向其他共同注册人披露其委托人的身份。在此背景下，每个运营商仍有责任根据制裁合规要求，对先前注册人的身份进行必要的核查。有关更多详情，请参阅 ECHA 的问答 1768 和问答 1896。有关制裁对数据共享影响的更多信息，请参阅欧盟委员会在此链接发布的常见问题解答。请特别参阅常见问题解答 2、3、5、8 和 15。
Answer (EN)
Upon the submission of an inquiry under Article 26 REACH, as a potential registrant you will receive access to the Co-Registrants’ page in REACH-IT, where you can find information on the previous registrants of your same substance. Depending on the information provided by those previous registrants, you will find information on the name of the manufacturer, the importer or their representative, their address and other contact details.At that point, you may become aware that the previous registrant who submitted the data you need for registration purposes is subject to EU sanctions. This may include cases where the data was previously submitted by an only representative of a non-EU manufacturer subject to such measures. The sanctions in question may include a prohibition to make economic resources available to the sanctioned party, a prohibition to engage in a transaction with that party or a prohibition to provide certain services.Depending on the circumstances of each case, these prohibitions may prevent the conclusion of a data sharing agreement between you and the previous registrant. If that is the case, you may, as a last resort, submit a data sharing dispute with ECHA. Further details on data sharing are available at Data sharing - ECHA (europa.eu) and in the Guidance on data-sharing.Note that registrants may have appointed a third party representative to hide their own name from their co-registrants or submitted a request to hide the registrant’s name from the public. Only representatives of non-EU manufacturers may also have opted for the identity of their principal not to be disclosed to other co-registrants. Against this background, it remains a responsibility of each operator to carry out the necessary checks on the identity of the previous registrants as required by sanction compliance. For further details, see ECHA’s Q&A 1768 and Q&A 1896.For more information on the impact of sanctions on data sharing, please see the FAQs published by the European Commission at this link. See in particular FAQs 2, 3, 5, 8 and 15.
