纳米材料的注册是否仅涉及有意生产的纳米材料？

Does the registration of nanomaterials concern only those that are intentionally produced?

所有符合 REACH 定义的纳米形态，只要该物质的进口/生产量达到或超过 1 吨/年/注册人，均须注册该物质的纳米形态。无论该纳米形态是否为有意生产，均须履行此义务。每位制造商/进口商均有责任对其物质进行表征，从而确定该物质是否包含符合纳米形态要求的形态。对于每一种符合纳米形态要求的形态，制造商/进口商必须对其进行表征，并在注册档案中报告表征信息。此外，制造商/进口商还必须确保提交相应的危害数据集。

The obligation to register nanoform(s) of a substance applies to all nanoforms meeting the definition set out in REACH, as soon as the substance is imported/manufactured in quantities of 1 tonne or more/year/registrant. This obligation applies irrespective of whether the nanoform was intentionally produced. Each manufacturer/importer is responsible for characterising its substance, and thereby identifying if the substance contains forms that qualify as nanoforms. For each form that qualifies as a nanoform, the manufacturer/importer must characterise the nanoform and report the characterisers in the registration dossier. In addition, they must ensure that a corresponding hazard dataset is submitted.
