下游用户 (DU) 使用已注册物质本身或混合物进行产品和工艺导向研究与开发 (PPORD) 时有哪些义务？

What are the obligations of a Downstream User (DU) who uses a registered substance, as such or in a mixture, for the purpose of product and process orientated research and development (PPORD)?

根据 REACH 规定，将物质用于 PPORD 目的的 DU 的义务可能有所不同，具体取决于 PPORD 活动是否包含在该物质的制造商或进口商提交的 PPORD 通知中。如果 DU 在制造商或进口商提交的 PPORD 通知中被列为客户之一，则 DU 在其供应商的责任下运营，并且必须遵守根据 REACH 第 9(4) 条设定的和/或其供应商告知的任何条件。如果 DU 停止将物质用于 PPORD 目的，并因此终止与其供应商的合作，则 DU 需要通知其供应商，因为供应商需要更新其通知以将 DU 从客户列表中删除。或者，DU 可以自行负责并主动将物质用于 PPORD 目的。由于 DU 不承担 REACH 第 5 条和第 6 条规定的注册义务，因此 DU 无需根据 REACH 第 9 条提交通知即可免除注册义务。如果企业按照保护工人和环境的法规要求充分控制对人类健康和环境的风险，即使其使用条件未包含在其供应商的扩展安全数据表中，或不建议使用，企业也无需编制企业社会责任 (DU CSR)（第 37(4)(f) 条）。根据第 38(1)(b) 条，如果企业出于 PPORD 目的使用超过 1 吨的注册物质，并享受第 37(4)(f) 条中的豁免，则必须向欧洲化学品管理局 (ECHA) 报告。

The obligations under REACH for a DU using a substance for the purpose of PPORD may differ, depending on whether or not the PPORD activity is covered by a PPORD notification made by the manufacturer or importer of the substance. A DU, who is listed in a PPORD notification submitted by the manufacturer or importer as one of the customers, operates under the responsibility of his supplier and must respect any conditions set in accordance with Article 9(4) of REACH and/or communicated to him by his supplier. If the DU stops using the substance for the purpose of PPORD and, by this, ends the cooperation with his supplier, he needs to inform his supplier, as the supplier will need to update his notification to remove the DU from the list of customers. Alternatively, a DU can use a substance for the purpose of PPORD under his own responsibility and initiative. Since a DU does not have the registration obligation of Articles 5 and 6 of REACH, there is no need for the DU to submit a notification under Article 9 of REACH to be exempted from the registration obligation. If he adequately controls the risks to human health and the environment in accordance with the requirements of legislation for the protection of workers and the environment, the DU is not required to prepare a DU CSR, even if his conditions of use are not covered in the extended SDS of his supplier or  the use is advised against (Article 37 (4) (f)). According to Art 38(1)(b), the DU must report to ECHA if using a registered substance at greater than 1 tonne for the purposes of PPORD and availing of the exemption in Art. 37(4)(f).
