答案（中文）
根据 NONS 指令，您可以对以下信息主张保密：吨位范围；（稳健）研究摘要；以及物质的 IUPAC 名称。根据 67/548/EEC 指令接受的保密性主张在 REACH 下仍然有效，前提是该信息在此期间尚未公开。ECHA 将评估保密性主张，如果发现该信息已公开，ECHA 将要求提供更多信息，然后再拒绝该主张。您无需为已根据 67/548/EEC 指令提出的主张付费。更多信息，请参阅如何更新您之前申报的物质 (NONS)。如果根据 67/548 指令请求对 IUPAC 名称保密，但与此同时 IUPAC 信息已在已发布的 EC 清单或任何其他公开来源中提供，则 ECHA 假定该请求已过期，除非注册人提供完整的理由，包括尽管信息已公开但仍然应保密的正当理由。根据 REACH 法规，除非声明为机密信息，否则以下信息也将在 ECHA 网站上发布：安全数据表中的信息（包括通知人名称、注册号、用途和建议禁止的用途）；物质的商品名；如果对分类和标签至关重要，则应包含物质的纯度以及已知危险的杂质和/或添加剂的成分。更多信息，请参阅《REACH 法规下的传播和保密手册》。ECHA 为非 ...更多信息可以在 NONS 问答中找到。
Answer (EN)
Under the NONS Directive you could claim confidentiality on:
Tonnage band;
(Robust) Study summary; and
IUPAC name of the substance.
Confidentiality claims accepted under Directive 67/548/EEC remain valid under REACH, in as far as the information has in the meantime not become available in the public domain. ECHA will assess the confidentiality claim and will – if the information is found to be publicly available – request further information before rejecting the claim.
You do not need to pay for claims that were already made under Directive 67/548/EEC. For more information, see How to update your previously notified substance (NONS)
For the case where confidentiality of the IUPAC name was requested under Directive 67/548, but the IUPAC information in the meantime is already available in the published EC Inventory or at any other publicly available source, ECHA assumes the request to be expired, unless the registrant provides a full justification that includes a valid reason why the information should still be kept confidential despite of the public availability.
Under REACH, it is foreseen that also the following information is published on the ECHA website, unless claimed confidential:
Information contained in the safety data sheet (including name of the notifier, registration number, uses and uses advised against);
Trade name of the substance;
If essential to classification and labelling, the degree of purity of the substance and the identity of impurities and/or additives which are known to be dangerous.
Further information is available in the manual on Dissemination and Confidentiality under the REACH Regulation.
ECHA gives the same possibilities to NONS notifiers as to other REACH registrants for claiming confidentiality. Therefore, if your company considers that this information should not be published on the ECHA website, you can introduce the relevant confidentiality claims. These confidentiality claims need to be justified and ECHA will charge a fee for each claim, in accordance with Article 119(2).
ECHA will assess the confidentiality claim and will – if the information is found to be publicly available or if the claim is not sufficiently justified – request further information before rejecting the claim.
