If a nanoform is introduced into a polymer during the polymerisation phase, do we have to register it, knowing that the nanoform is present in the final polymer without emission?

在聚合阶段将纳米形态引入聚合物之前，必须先制造或进口纳米形态。如果您每年制造或进口的引入聚合物的纳米形态物质超过 1 吨，则必须注册该纳米形态，即使它随后用于制造聚合物。但是，如果您从欧盟的供应商处购买纳米形态，则无需注册，但供应链中的制造商或进口商必须注册。在后一种情况下，您必须确保您对纳米形态的使用在制造商/进口商的注册范围内。最后，如果您进口聚合物，且供应链上游的参与者尚未注册该纳米形态，并且满足 REACH 第 6(3) 条规定的条件，则必须提交纳米形态的注册（参见问答 1674）。

Before being introduced into the polymer during the polymerisation phase, the nanoform has to be manufactured or imported. If you manufacture or import in a quantity above 1 tonne per year the substance of which nanoform is introduced in the polymer, you must register the nanoform, even if it is then used in the manufacturing of a polymer. However, if you buy a nanoform from a supplier in the EU, you do not have to register it, but the manufacturer or importer in the supply chain must do so. In the latter case, you have to ensure that your use of the nanoform is covered by the registration of the manufacturer/importer.  Finally, if you import the polymer you must submit a registration for the nanoform if it has not already been registered by an actor up the supply chain and if the conditions set out in Article 6(3) of REACH are met (see Q&A 1674).
