How are the costs of data shared and can I receive support from ECHA if costs do not seem justified?

每种物质共享数据的成本可能存在显著差异，具体取决于所涉及的研究成本、共享数据的注册人数量以及其他因素。成本分摊协议通常要求各方就以下事项达成一致：• 数据的可靠性、相关性和充分性（“数据质量”）；• 数据的经济价值（“数据估值”）；以及• 各方如何分摊商定的价值（“成本分配和补偿”）。注册人需要尽一切努力以公平、透明和非歧视的方式就数据共享及其成本达成协议。注册人需要分担其为满足注册要求而必须提交的信息的成本。公司不应被迫为其不需要的研究付费。欧洲化学品管理局 (ECHA) 已发布关于数据共享谈判期间应考虑事项的通用建议。此外，还提供数据共享谈判的实用建议。ECHA 不会参与（潜在）注册人之间的讨论，也不负责监管或评估数据共享的成本。 ECHA 无法协助潜在注册人与先前注册人或数据所有者进行谈判。作为最后手段，ECHA 可以协助解决现有注册人和潜在注册人之间的数据共享纠纷。有关数据共享纠纷的更多详情，请参阅 ECHA 网站上的相应页面。

The costs of shared data for each substance may vary significantly, depending on the costs of the studies involved, the number of registrants sharing the data and other factors. An agreement on cost sharing usually requires parties to agree on:• Reliability, relevance and adequacy of the data ("data quality");• Economic value of the data ("data valuation"); and• How the agreed value is shared among parties ("cost allocation and compensation"). Registrants need to make every effort to reach an agreement on data sharing and its costs in a fair, transparent and non-discriminatory manner. Registrants need to share the costs of information that they are required to submit to satisfy their registration requirements. Companies cannot be forced to pay for studies that they do not need. ECHA has published generic advice on what to take into account during the data-sharing negotiations. Additionally, practical advice for data sharing negotiations is available.ECHA will not participate in the discussions between (potential) registrants and has no remit in regulating or assessing the costs of sharing data. ECHA cannot assist a potential registrant in its negotiations with previous registrants or data owners. As a last resort, ECHA can assist in resolving data sharing disputes between existing and potential registrants.
