注册号码何时必须传达至供应链？

When does the registration number have to be communicated down the supply chain?

对于根据 REACH 法规第 31 条规定需要安全数据表 (SDS) 的物质或混合物，REACH 附件 II 要求在 SDS 可用时提供根据 REACH 法规第 20 条分配的注册号。REACH 法规第 31(9) 条规定了应立即提供更新版 SDS 的具体情况。收到注册号本身并未列为此类情况之一。然而，由于分配注册号对该物质的下游用户具有重大潜在利益，因此建议立即或在下次供应该物质或含有该物质的混合物时向现有客户发送更新版 SDS。对于首次收到该物质或混合物的客户，当然应该更新 SDS，以包含注册号。特别注意，第 31(9) 条的最后一句要求“注册后的任何更新都应包含注册号”。请注意，修订 REACH 法规附件二的 (EU) No 453/2010 法规中详细规定了联合提交中涉及个人注册人的部分（原始完整注册号的后四位数字），供应商（分销商或下游用户）何时可以省略。同样，REACH 第 32(1)(a) 条规定，当根据第 32 条（无需 SDS 的物质和混合物的告知义务）必须将注册号告知客户时，应提供注册号（如有）。REACH 第 32(3) 条规定了需要立即更新的情况。同样，收到注册号本身并未列为此类情况之一。出于类似原因，发送更新信息可能仍是可取的。再次注意，REACH 第 32(3) 条的最后一句也要求“注册后的任何更新都应包含注册号”。更多指南请参阅《注册指南》第6.1.2节“向客户提供其他信息”，该指南可在欧洲化学品管理局（ECHA）网站http://echa.europa.eu/guidance-documents/guidance-on-reach上获取。无论相关注册截止日期是否已过，REACH第31条和第32条的规定均适用。

For a substance or mixture requiring a Safety Data Sheet (SDS) according to Article 31 of the REACH Regulation, Annex II of REACH requires that the registration number assigned in accordance with Article 20 of REACH be given in the SDS when it is available. Article 31(9) of REACH gives specific occasions on which an updated SDS should be supplied without delay. Receipt of a registration number per se is not listed as one of these occasions. However as the assignment of a registration number is of major potential interest to downstream users of the substance it may be recommendable to send existing customers an updated SDS either immediately or on the next supply of the substance or of a mixture containing it. The SDS should of course be updated to incorporate the registration number(s) for customers who are going to receive the substance or mixture for the first time. Note in particular that the final sentence of Article 31(9) requires that "any updates following registration shall contain the registration number". Please note that there are detailed provisions in Regulation (EU) No 453/2010 amending Annex II to the REACH Regulation regarding when the part of the registration number referring to the individual registrant of a joint submission (the last four digits of the original full registration number) may be omitted by a supplier who is a distributor or a downstream user.    Similarly, Article 32(1)(a) of REACH indicates that when registration numbers have to be communicated to customers according to Article 32 (Communication duties for substances and mixtures not requiring an SDS) the registration number, if available, should be supplied. The occasions on which an update without delay is required are given in Article 32(3) of REACH. Again, receipt of a registration number per se is not listed as one of these occasions. For similar reasons it may be deemed to be desirable to nonetheless send updated information. Note again that the last sentence of Article 32(3) of REACH also requires that "any updates following registration shall contain the registration number". Further guidance can be found in section 6.1.2-'Provide other information to customers' in the Guidance on Registration available on the ECHA website at: http://echa.europa.eu/guidance-documents/guidance-on-reach. The provisions of Articles 31 and 32 of REACH apply irrespectively of whether the relevant registration deadline is still to come or has already elapsed.
