IMDG CODE 国际海运危险货物规则第41-22版正在路上，根据IMO的最新建议，从2023年1月1日起就可选择使用《海运危规》第41-22号修正案的内容来指导相关的工作。
从2023年1月1日到2023年12月31日有一个为期12个月的过渡期，在此期间可以继续使用之前的修正案，即40-20版。
也就是说当前大家正在使用的40-20版可以使用到2023年底，到2024年初强制使用第41-22版。
声明：本文的目的是对正在提出的修改作一个简要概述，不应视为修正案的完整清单。所有修正案和适用规定的全部细节必须参阅第41-22号修正案的正文。
IMDG规则变更摘要41-22
- 与往常一样，这次没有重大的修改，与联合国第22版《Model regulations》也就是我们常说的桔皮书的更新保持一致。
- 第1.2章:定义: 对现有条目有很多变更，包括新的定义:IAEA规则、内部容器、压力容器外壳和服务设备。
- 第2部分:分类 在2.4和2.5章中列出了一种自反应物质和三种有机过氧化物的新技术名称。
- 第3部分:危险货物一览表 添加了一个新的编码，UN 3550 (二氢氧钴粉，含有不少于10%的可呼吸颗粒)，类别号6.1。
两个现有的编号，UN 1169(萃取物，芳香，液体)和UN 1197(萃取物，调味，液体)合并为UN 1197(萃取物，液体，用于风味或香气)。
UN 1891（乙基溴）由6.1类改为3类，次级危害6.1。LQ、EQ和EmS的值也随之改变。
UN 3527 (PGII和PGIII)，聚酯树脂套件，固体基材，将“E0”改为“见SP340”
强酸和弱酸之间的区别被删除了。所有带有SGG1a强酸性的条目现在都包含SGG1酸性。UN 1439（重铬酸铵）是唯一包含积载编码SG75的条目，之前要求是与SGG1a -强酸“分离”，现在包含SG35，需要与所有酸分离。
- 3.3章:特别规定:有新的条目，如un3538的SP396，含不易燃、无毒气体的物品，N.O.S, un1003的sp397，空气，压缩和un1012丁烯的SP398。特别条款188和225在措辞上有微小的改动。
- 第4.1章:包装说明——在一些包装说明中增加了各种注释，以实现4.1.3.3中增加的新句子，该句子澄清了在使用联合国包装以外的物品时，它们不受通常400公斤的限制。
P200对氟和惰性气体的混合物有新的规定。表2中更新了UN 1008、2196和2198的LC50值，对于后两者，这增加了可能使用的压力容器的类型。
P621部分(1)现在允许不可拆卸的头桶和盒子。
IBC07增加了新的特殊包装“B40”，为新的UN 3550提供了灵活的中型散货箱(13H3和13H4)
- 第5部分:托运程序-要求在锂电池标记上电话号码现在被取消，过渡时期到2026年底。
“熔融”物质现在必须作为补充危险货物描述PSN信息的一部分加以识别
有一个新的通用要求，以确保在特殊规定要求附加信息的所有情况下，在运输单据上注明这一点。
- 第6部分:包装的构造和测试——在第6部分中有许多关于包装、中型散货箱、储罐等的设计、构造和测试的变化。这些变化主要是为了澄清需求的含义和使用的术语。在第6.2章中有大量的修改，并增加了一个全新的第6.10章，涵盖了由纤维增强塑料(FRP)材料制成的外壳的便携式罐体的设计、建造、检验和测试。
- 第7.2章:隔离—为了删除“强酸”和“酸”之间的区别，隔离代码“SG75”被删除
以上为相关修改简要概述，以下附上相应的英文内容，供您对照阅读。
