答案（中文）
GHS 是通过欧盟法规 (EC) No. 1272/2008（关于物质和混合物分类、标签和包装）（CLP 法规）的形式实施的，该法规具有法律约束力，可直接应用于欧盟成员国，而 GHS 则不具有法律约束力。GHS 和 CLP 并不相同，因为 CLP 也基于旧的欧盟分类和标签法规，即危险物质指令 67/548/EEC (DSD) 和危险制剂指令 1999/45/EC (DPD)。此外，基于所谓的联合国 GHS“构建模块方法”，CLP 并不包含某一危险类别中包含的所有危险类别，因为它们不属于 DSD，例如危险类别易燃液体中的第 4 类，或危险类别皮肤腐蚀/刺激中的第 3 类（轻度刺激物）。 CLP 包含特殊的标签和包装规则，这些规则不属于联合国 GHS，但源自 DSD 和 DPD，例如小包装规则（CLP 第 29 条）、某些混合物补充信息规则（CLP 附件 II 第 2 部分）以及儿童安全扣件或触觉警告规定。此外，CLP 还包含针对某种物质同时受 CLP 和运输法规管辖的情况的规则（CLP 第 33 条）。需要注意的是，与联合国 GHS 不同，CLP 不包含关于安全数据表的具体规则，因为安全数据表已通过 REACH 第 31 条和附件 II 受到监管。
Answer (EN)
The GHS was implemented through Community legislation in the form of Regulation (EC) No. 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP Regulation) which is legally binding and directly applicable in the Member States of the EU, whereas GHS is not legally binding.
GHS and CLP are not identical because CLP is also based on the old EU legislation on classification and labelling, i.e. the Dangerous Substances Directive 67/548/EEC (DSD) and the Dangerous Preparations Directive 1999/45/EC (DPD).
In addition, and based on the so-called UN GHS "building block approach", CLP does not include all the hazard categories included for a hazard class because they were not part of DSD, e.g. category 4 of the hazard class flammable liquids, or category 3 (mild irritant) of the hazard class skin corrosion/irritation. CLP includes special labelling and packaging rules that are not part of the UN GHS, but which were brought over from the DSD and DPD, e.g. the rules on small packaging (CLP Article 29), on supplemental information for certain mixtures (Part 2 of Annex II to CLP) and for the provision of child-resistant fastenings or tactile warnings. Also, it includes rules for the situation when a substance is both covered by CLP and by transport legislation (CLP Article 33).
It should be noted that in contrast to the UN GHS, CLP does not include specific rules on Safety Data Sheets as they are already regulated by REACH, through its Article 31 and Annex II.
