如果我的纳米形态/用途未被供应商覆盖，我该怎么办？

What do I need to do if my nanoform/uses are not covered by my supplier?

如果您认为您所创建的纳米形态或其用途未包含在供应商的安全数据表 (SDS) 中，则您有三种选择：停止使用和创建未包含的纳米形态。要求您的供应商在其化学安全报告中包括您所创建的纳米形态以及用途或使用条件，并为您提供其暴露场景（参见问答 1834）。在这种情况下，您必须向供应商提供足够的信息，以便他们进行评估。如果您要求涵盖新的纳米形态，则此信息通常应包括纳米形态的特征（附件 VI 特征），除非您的供应商同意为您生成此信息。如果需要生成新的危险数据，您可以与您的供应商商定谁来执行测试和/或承担费用。如果您的供应商拒绝涵盖您的用途/纳米形态，或者供应商不建议您使用/纳米形态，您可以尝试寻找其他涵盖您的用途/纳米形态的供应商。在寻找可以覆盖您的纳米形态的潜在供应商时，查阅 ECHA 传播网页以检查您的纳米形态是否在物质注册档案的覆盖范围内可能会有所帮助，从而了解找到覆盖您的纳米形态的供应商的可能性。或者，您可以自己覆盖纳米形态或用途。在这种情况下，您必须进行自己的化学品安全评估，并为您的用途和使用条件准备自己的下游用户化学品安全报告 (DU CSR)，除非适用豁免（第 37 条，(c) 用量 <1 吨/年或 (f) PPORD 用途）。当您执行 DU CSR 或依赖豁免时，必须将此情况通知 ECHA（参见问答 1837）。有关如何处理暴露情景的更多信息，请参阅：实用指南 13：“下游用户如何处理暴露情景”。

If you conclude that the nanoform you have created or its uses are not covered by the information in your supplier’s safety data sheet (SDS), there are three options available to you: Stop the uses and the creation of the nanoform that is not covered. Ask your supplier to include the nanoform you have created, as well as the use(s) or conditions of use in their chemical safety report and to provide you with an exposure scenario for it (see Q&A 1834). In this case, you must make sufficient information available to your supplier to enable them to make an assessment. In the case that you are requesting a new nanoform to be covered, this information should normally include the characterisation of the nanoform (Annex VI characterisers) unless your supplier agrees to generate this information for you. If new hazard data needs to be generated, you may agree with your supplier on who is performing the testing and/or covering the costs.  If your supplier refuses to cover your uses/ your nanoform or if the supplier advices against your use/ your nanoform, you can try to find another supplier that covers your uses/ nanoform. When looking for a possible supplier that can cover your nanoform, it may be useful to consult the ECHA dissemination web pages to check whether your nanoform is covered by the registration dossier of the substance to get an idea on how likely it is to find a supplier that covers your nanoform. Alternatively, you can cover the nanoform or uses yourself. In this case, you must carry out your own chemical safety assessment and prepare your own downstream user chemical safety report (DU CSR) for your uses and conditions of use, unless exemptions apply (Article 37, (c) use <1 tonne/year or (f) PPORD use). When you perform a DU CSR, or you are relying on exemptions, you must notify this to ECHA (see Q&A 1837).
