2018 年注册截止日期之后我还能继续使用 SIEF 吗？物质信息交换论坛 (SIEF) 和联盟之间有什么区别？

Can I continue using SIEFs after the registration deadline of 2018 and what is the difference between a substance information exchange forum (SIEF) and a consortium?

公司可以通过多种方式在 REACH 法规下组织合作。这些合作形式多种多样，从松散的合作方式（例如，使用 IT 工具在联合提交的所有成员之间进行沟通）到更结构化、更具约束力的模式（例如，通过合同创建的联盟）。在 2018 年 5 月 31 日的上一个 REACH 注册截止日期之前，分阶段物质必须参与 SIEF（物质信息交换论坛）。然而，在分阶段期结束后，2019 年 10 月 9 日的委员会实施条例 2019/1692 鼓励共同注册人使用类似的非正式沟通平台，以使他们能够履行 REACH 和委员会实施条例 2016/9 规定的持续注册和数据共享义务。另一方面，加入联盟则完全是自愿的。如果一个或多个非正式沟通平台的部分或全部参与者决定组建联盟，他们可以自由决定其范围、目的、期限、成员资格或退出条件等安排，只要这些安排不违反欧盟竞争规则。有关合作形式的更多信息，请参阅数据共享指南。

There are several possible ways in which companies can organise their cooperation under REACH. These forms of cooperation can vary from loose ways of cooperating (e.g. IT tools to communicate between all members of a joint submission) to more structured and binding models (e.g. consortia created by means of contracts).   Participation in a SIEF (substance information exchange forum) was mandatory for phase-in substances until the last REACH registration deadline of 31 May 2018. After the end of the phase-in period, however, the Commission Implementing Regulation 2019/1692 of 9 October 2019 encourages co-registrants to use similar informal communication platforms to enable them to meet their continuing registration and data sharing obligations under REACH and Commission Implementing Regulation 2016/9.  Membership of a consortium is, on the other hand,  entirely voluntary. If some or all participants of one or more informal communication platforms decide to form a consortium, they are free to decide the arrangements regarding scope, purpose, duration, conditions for membership or leaving etc., as long as these do not contravene EU competition rules.  Additional information on forms of cooperation can be found in the Guidance on data sharing.
