如果共同注册人声称不生产纳米形式但未提供任何证据，物质的其他注册人应如何处理？

How should the other registrants of a substance proceed if a co-registrant claims not to produce nanoforms but does not provide any proof for this?

每个注册人负责注册他们自己生产或进口的纳米形态。每个注册人必须单独提交附件 VI 所要求的信息，包括纳米形态或纳米形态组的特征。附件 VII-X 所要求的信息可以代表成员注册人在主注册人档案中联合提交。或者，每个注册人可以通过选择退出机制单独提交这些信息。如果共同注册人声称不生产纳米形态但未提供任何证据支持其主张，则该物质的其他注册人应按照 REACH 要求继续注册其纳米形态。在 2020 年 1 月 1 日之后生产/进口该物质纳米形态且未进行涵盖这些纳米形态的注册的注册人违反了 REACH 法规规定的义务，这可能导致国家执法机构采取执法措施。

Each registrant is responsible for registering the nanoforms that they themselves manufacture or import. The information required by Annex VI, including the characterisation of nanoforms or sets of nanoforms, must be submitted separately by each registrant.  The information required by Annexes VII-X can be submitted jointly in the lead registrant dossier on behalf of the member registrants. Alternatively, this information can be submitted separately by each registrant via the opt-out mechanism. If a co-registrant claims not to produce nanoforms but does not provide any proof to support their claim, the other registrants of the substance should proceed with the registration of their nanoforms following the REACH requirements.    Registrants that manufacture/import nanoforms of the substance after 1 January 2020 without a registration that covers these nanoforms are in breach with their duties under the REACH regulation, which may lead to enforcement measures by national enforcement authorities.
