对于回收物质以及 REACH 附件 IV 和 V 中所含物质，是否必须将注册号传达至整个供应链？

对于回收物质以及 REACH 附件 IV 和 V 中所含物质，是否必须将注册号传达至整个供应链？

Does the registration number have to be communicated down the supply chain for recovered substances and substances included in Annex IV and V of REACH?

附件四和附件五所列物质可免于注册（REACH法规第2条第7款a和b项）。附件四列出的物质，其信息足以表明对人类健康和环境的风险极小。附件五涵盖13类物质，如果满足附件五所述条件，则这些物质的注册被视为不适当或不必要。满足REACH法规第2条第7款d项条件的回收物质也可免于注册。回收经营者如果能够证明某种物质与已注册物质相同，并根据REACH法规第31或32条拥有所需信息，则可免于注册该物质。符合这些豁免条件的制造商或进口商无需提交注册档案。在这种情况下，制造商或进口商将无法获得注册号，因此也无法在供应链中传递此类注册号。为避免混淆，安全数据表中可能会解释该物质没有注册号的原因，如《安全数据表编制指南》第4.1节所述。希望享受此类豁免的公司必须评估其物质是否符合豁免条件。他们还必须（根据要求）向主管部门提供适当的信息，以证明其物质符合豁免条件。更多信息，请参阅为REACH第2(7)条所涵盖物质的接收者提供关键信息的情况说明书，其中涵盖了他们通常可以从供应商处获得的信息。您可以在此处找到该情况说明书：http://echa.europa.eu/documents/10162/13655/reach_factsheet_on_communication_obligation_en.pdf

Substances included in Annex IV and substances covered by Annex V are exempted from the registration requirement (Article 2 (7) (a) & (b) of REACH). Annex IV lists substances for which sufficient information is available to consider them as causing minimum risk to human health and the environment. Annex V covers 13 categories of substances for which registration is deemed to be inappropriate or unnecessary, if the conditions described therein are fulfilled. Recovered substances fulfilling the conditions of Article 2 (7) (d) of REACH are also exempted from the registration requirement. A recovery operator who establishes the sameness of a substance with one already registered and who possesses the required information according to Articles 31 or 32 of REACH is exempted from registration of that substance.   Manufacturers or importers that fall under any of these exemptions need not submit a registration dossier. In such a situation, the manufacturer or importer will not obtain a registration number and consequently will not be able to communicate such a registration number in the supply chain. In order to avoid confusion an explanation as to why there is no registration number for that substance may be given in the safety data sheet as explained in section 4.1 of the Guidance on the compilation of safety data sheets.   Companies that wish to benefit from such an exemption must assess whether their substances qualify for the exemption. They also have to provide the authorities (on request) with appropriate information to prove that their substances fulfil the exemption conditions.   Further information can be found in the factsheet providing key information for recipients of substances covered by Article 2(7) of REACH, covering what information they can generally expect from their supplier.
