答案（中文）
您需要报告物质中每种成分的浓度范围（即最小值和最大值）和典型浓度。这些浓度应代表该物质在生产/进口时的状态，且不应涵盖其他物质。例如，您可以从经认证的规格限值中获取这些信息，这些限值通常包含在物质的分析证书 (CoA) 中。有关在 IUCLID 6 中报告物质身份的技术说明，请参阅《如何准备注册和 PPORD 档案手册》第 8.3.1-8.3.2 节。
Answer (EN)
You need to report both concentration ranges (i.e. minimum and maximum values) and a typical concentration for each constituent of your substance. These should be representative of the substance as manufactured/imported and should not cover different substances. You can obtain this information, for example, from certified specification limits that often form part of a certificate of analysis (CoA) of substances. For technical instructions on reporting the substance identity in IUCLID 6, see section 8.3.1-8.3.2 in the Manual on how to prepare registration and PPORD dossiers.
