答案（中文）
您的注册信息由您自行负责，因此请始终保持最新状态。安全数据表 如果您需要向客户提供安全数据表，则需要在下次更新时在安全数据表中包含您的注册号。此外，如果您进行了化学品安全评估并需要开发暴露场景，则必须将其附加到安全数据表中，概述该物质安全使用的特定用途条件。这需要尽快完成。中小企业验证 如果您声称自己是中小企业并受益于降低的注册费，ECHA 可能会验证贵公司的规模。确保您的 REACH-IT 帐户包含所有必要的文件，以证明贵公司的规模。联合提交管理和数据共享 我们强烈建议您建立一个在联合提交中讨论的机制，并在必要时用于档案更新。例如，您还必须共享数据并向新来者开放联合提交的访问权限。您可以通过公平、透明和非歧视的方式分摊成本来收取数据访问费用。档案评估：ECHA 将对收到的至少 20% 的注册档案进行合规性检查，以验证所提交的信息是否符合法律要求。档案评估的结果可能是要求提供补充信息。此外，ECHA 将审查档案中包含的测试方案。对于在 2018 年 5 月 31 日截止日期前提交的注册，ECHA 将于 2022 年 6 月 1 日前完成审查，对于其他注册，ECHA 将于 180 天内完成审查。如果您的注册档案信息正在接受评估，ECHA 将通过 REACH-IT 与您沟通，因此我们建议您定期查看您的帐户。
Answer (EN)
Your registration remains your responsibility, so keep it always up-to-date.
Safety Data Sheet
If you need to give your customers safety data sheets, you will need to include your registration number in the safety data sheets the next time you update them. In addition, if you have conducted a chemical safety assessment and needed to develop exposure scenarios, you have to attach them to the safety data sheet, outlining the use-specific conditions of safe use of the substance. This needs to be done as soon as possible.
SME verification
If you have claimed you are an SME and have benefited from the reduced registration fees, ECHA may verify the size of your company. Make sure that your REACH-IT account includes all the necessary documentation to justify the size of your company.
Joint Submission management and Data sharing
We strongly recommended that you put in place a mechanism discuss within your joint submission and for dossier update, when necessary. For example, you must also share data and give access to the joint submission to newcomers. You can charge for access to the data by sharing the costs in a fair, transparent and non-discriminatory way.
Dossier evaluation
ECHA will check the compliance of at least 20% of the received registration dossiers to verify that the information submitted is compliant with the legal requirements. The outcome of this dossier evaluation may be a request for additional information. Additionally, ECHA will examine the testing proposals included in the dossiers. This will happen by 1 June 2022 for registrations submitted for the deadline of 31 May 2018, and within 180 days for other registrations.
ECHA will communicate with you via REACH-IT, if the information of your registration dossier is being assessed, so we invite you to check your account regularly.
