如何收集供应链中的用途和吨位信息？注册人和下游用户的职责是什么？

How can I gather the information on uses and tonnages in the supply chain? What are the duties of registrants and downstream users?

筛选是在物质层面进行的，因此会考虑来自该物质所有注册档案的用途信息。因此，所有注册人的利益都在于确保注册档案中反映最新的用途。我们了解，从供应链下游用户收集有关用途和每种用途的吨位信息可能存在困难。但是，所有人都应该清楚，如果某些用途与进一步的监管行动相关，即使该物质可能仅出现在一个成员档案中，成员国也会考虑对其采取进一步行动。在手动筛选层面收集此类信息可能既困难又耗时，但是，如果该物质进入进一步行动阶段，那么与成员国进行交流的时间和可能性就会更多，而且这些信息仍然会影响该物质预期行动的结果。如果与下游用户沟通有困难，我们鼓励您尝试解释这些考虑因素。出于保密考虑，下游用户直接向负责物质评估或RMOA等的成员国提供此类信息可能会更容易。然而，应牢记，尽早澄清用途符合注册人、下游用户和主管部门的利益。此外，ECHA认为，如果下游用户将从供应商处收到的吨位细分为通用用途（可能参考IUCLID 6中的累积吨位字段：消费者用途；广泛的专业工人；工业用途；使用寿命），则无需披露机密商业信息（CBI）。主注册人和共同注册人均有责任更新其注册档案中的信息。

The screening is done at the level of the substance and therefore considers information on uses coming from all registration dossiers for that substance. As a consequence, it is in the interest of all registrants to have up to date uses reflected in the registration dossier. We are aware that it may be difficult to gather information on uses and tonnages per uses from downstream users in the supply chain. However, it should be clear to all that if some uses are relevant for further regulatory action, the Member State will consider the substance for further action even though it may only be present in one member dossier. It may be difficult and time consuming at the level of the manual screening to gather such information however if the substance is moved to further action then there will be more time and more possibilities for exchange with the Member States and this information can still influence the outcome of the action envisaged for that substance.   If it is difficult to communicate with your downstream users, we would encourage you to try to explain those considerations. For confidentiality, it will potentially be easier for the downstream user to provide such information directly to the Member State in charge, for instance, of substance evaluation or RMOA. However, it should be kept in mind that providing clarification on the uses as early as possible is in the interest of registrants, downstream users and authorities. In addition, in ECHA's view downstream users would not disclose confidential business information (CBI) if they break down the tonnage received from their supplier into generic type of use (possibly making reference to the cumulative tonnage fields in IUCLID 6: consumer uses; widespread professional workers; industrial use; service life. Both lead registrants and co-registrants are responsible for updating the information in their registration dossiers.
