下游用户如何知道他们的物质是否已经注册？

How can a downstream user know, if their substance has been registered?

鼓励物质本身或混合物的制造商和进口商与该物质的下游用户或分销商沟通他们是否以及何时打算注册该物质，以便下游用户或分销商在必要时寻找替代供应源。物质注册后，供应商有义务根据 REACH 第 31 条在安全数据表中或（如果适用）根据第 32 条将注册号告知供应链下游。下游用户可以检查其投放市场的物质本身或混合物的注册状态（参见问答 399），以遵守 REACH 第 5 条规定的义务，即仅将符合 REACH 注册要求的物质投放市场。如果下游用户怀疑其供应商应该已经注册该物质，则应立即联系供应商。他们应确保对其业务至关重要的物质已注册并涵盖其用途。另请注意，您的供应商未注册该物质可能有正当理由，例如吨位低于每年1吨或该物质获得REACH法规豁免（附件五）。更多信息，请参阅我们影响下游用户的问题列表。

Manufacturers and importers of a substance on its own or in a mixture are encouraged to communicate with the downstream users or distributors of the substance with regard to whether and by when they intend to register the substance to enable the downstream user or distributor to seek alternative sources of supply if necessary. Once the substance has been registered, there is an obligation for the supplier to communicate the registration number down the supply chain either in the safety data sheet according to Article 31 or, if applicable, according to Article 32 of REACH. A downstream user can check the registration status (see Q&A 399) of the substances on their own or in a mixture they place on the market, in order to comply with the obligation imposed by Article 5 of REACH to place on the market only substances that comply with the registration requirements under REACH. If a downstream user suspects that their supplier should have already registered the substance, they should contact the supplier immediately. They should make sure that substances critical to their business are registered and that their uses are covered. Note also, that there may be a valid reason as to why your supplier has not registered the substance, e.g. the tonnage is below 1tpa or the substance is exempted (Annex V) from REACH.
