如果我在获取想要进口的 UVCB 物质的制造过程详细信息时遇到困难，该怎么办？

What should I do if I encounter difficulties getting hold of the manufacturing process details of the UVCB substance I intend to import?

首先，您需要确定哪些生产工艺信息与您的 UVCB 物质识别相关，如问答 1199 和《REACH 和 CLP 物质识别与命名指南》第 4.3 章所述。您对 UVCB 物质的成分了解得越多，就越不会依赖生产工艺来识别您的物质。例如，如果您可以根据成分信息确定反应产率和残留起始原料的含量，则可能无需指定用于生产该物质的反应物比例。但是，您仍然需要解释为什么某些预期提交的生产工艺要素未提供。ECHA 已准备了一个模板，可用于从非欧洲经济区制造商处收集必要的信息。如果缺少生产工艺信息导致您无法识别物质，且非欧洲经济区制造商未直接与您共享此信息，您可以建议 UVCB 物质的非欧洲经济区制造商根据 REACH 第 8 条指定唯一代表 (OR)。

You first need to define which information on the manufacturing process is relevant for the identification of your UVCB substance, as explained in Q&A 1199 and in Chapter 4.3 of the Guidance for identification and naming of substances under REACH and CLP. The more you know about the composition of the UVCB substance, the less you will be dependent on the manufacturing process to identify your substance. For instance, you may not need to specify the ratio of reactants used to manufacture the substance if you can define the reaction yield and the content of residual starting materials from the compositional information. Nonetheless, you will still need to explain why some elements of the manufacturing process expected to be submitted are not provided.ECHA has prepared a template that can be used to collect the necessary information from the non-EEA manufacturer. If the missing information on the manufacturing process prevents you from identifying the substance and the non-EEA manufacturer does not share this information directly with you, you may propose to the non-EEA manufacturer of the UVCB substance that they appoint an only representative (OR) in accordance with Article 8 of REACH.
