答案（中文）
一旦您向 ECHA 提交了查询档案，REACH-IT 就会执行一系列验证。验证完成后，对于大多数已注册或成功查询的物质，ECHA 会将查询者引导至 REACH-IT 中的相关共同注册人页面，在该页面他们可以找到同一物质的其他注册人和潜在注册人的联系方式。相反，对于没有注册人或潜在注册人或标识符不明确的物质，ECHA 会验证物质身份信息。如果 ECHA 能够分配查询编号和相关物质标识符，您将收到查询被接受的通知，并可以访问共同注册人页面，该页面将提供以下信息：联系方式：先前注册人的姓名和地址，以及适用时其他查询者（潜在注册人）的姓名和地址。研究：每个端点的提交者联系方式列表，以及12年前提交的（可靠）研究摘要的UUID。此信息使潜在注册人能够直接从之前的注册人处索取这些可靠研究摘要。如果您已分配列表编号和列表名称，则需要以“.i6z”文件格式下载列表编号（参见问答1258）。如果由于物质身份信息缺失和/或不一致而导致ECHA无法处理您的查询档案，您将在REACH-IT中收到一条说明所需更改的通知。在这种情况下，您需要解决物质数据集中描述的问题，然后提交新的查询档案。REACH法规并未规定ECHA处理查询档案的时间。但是，ECHA的目标是在20个工作日内提供查询结果。
Answer (EN)
Once you have submitted your inquiry dossier to ECHA, REACH-IT executes a series of verifications. After these are completed, for most already registered or successfully inquired substances, ECHA directs inquirers to the relevant Co-Registrants page in REACH-IT where they can find contact details of other registrants and potential registrants of the same substance.
In contrast, for substances where no registrants or potential registrants exist or with ambiguous identifiers, ECHA verifies the substance identity information.
For cases where ECHA is able to assign an inquiry number and relevant substance identifiers, you will receive a communication on the acceptance of the inquiry and access to the co-registrants’ page where the following information will be available:
Contact details: names and addresses of the previous registrants and, if appropriate, other inquirers (potential registrants).
Studies: a list of the submitters’ contact details for each endpoint and the UUIDs of the (robust) study summaries which have been submitted more than 12 years earlier. This information enables the potential registrant to request these robust study summaries directly from the previous registrants.
If you were assigned a list number and a list name, you will need to download the list number in “.i6z” file format (see Q&A 1258).
For cases where ECHA is not able to process your inquiry dossier due to missing and/or inconsistent substance identity information, you will receive a communication in REACH-IT describing the necessary changes. In this case you will need to address the described issues in the substance dataset and then submit a new inquiry dossier.
The REACH Regulation does not impose any timeframe on ECHA for processing an inquiry dossier. However, ECHA aims to provide the inquiry outcome in 20 working days.
