IMDG code amendment 41-22

Dangerous Goods Code for Packaged Goods – Latest amendments enter into force on 1 January 2024

Published: 21 November 2023

The International Maritime Dangerous Goods (IMDG) Code, an important mandatory code for the shipment of dangerous packaged goods by sea, will be entering into its 41st amendment on 1 January 2024.  

The amendment, known as Amdt 41-22, will enter into mandatory force on 1 January 2024. It is currently running under voluntary application where member government states have the option to implement it earlier. This also means that Amdt 40-20 will cease to apply on 31 December 2023 when Amdt 41-22 takes over.  

One of the changes is the introduction of a new chapter on “Provisions for the design, construction, inspection and testing of portable tanks with shells made of fibre-reinforced plastics (FRP) materials”. It provides information on the application and general requirements, including the provision for the design, construction, inspection and testing of FRP portable tanks. 

We have provided a summary of the more significant amendments effected by Amdt 41-22 in our Cargo Section / IMDG Code

The hard copy of the Code, IMDG Code, 2022 edition (including Amendment 41-22), is available for purchase and this can be done through your local distributor provided by the IMO website
