IMDG Code Amendment: Corrigenda to Amendment 39-18

imdg code amendment 39-18


The International Maritime Dangerous Goods (IMDG) Code is the mandatory framework for all aspects of handling dangerous goods for ocean transport which must be complied by entities such as manufacturers, packers, shippers, and in-transit shipments such as road and rail. The IMDG Code prescribes methods for classification, identification, packing, marking, labeling, stowage, and segregation to name a few. The most recent version incorporates amendment 39-18 and is authorized for use as of 1 January 2019 and mandatory as of 1 January 2020. Aside from this document, enrolling in an online hazmat training course is essential.

To kick off 2020 the International Maritime Organization has recently published a Corrigenda to Amendment 39-18. Many of the changes are minor text corrections and improvements. The new version include: 


  • Minor text corrections to the classification provisions in 2.4.2, 2.5.3, 2.8.3, and 2.9.2
  • Numerous revisions to the entries in the segregation groups so that the proper shipping names match their relevant dangerous goods list entry
  • UN1512 removed from segregation groups 2, 7 and 12
  • In the dangerous goods list (*) there have been numerous changes to UN Number entries to reflect:
  • Repositioning of SGG codes above SG codes to provide consistent ordering
  • Updates to many entries which contain reference to explosive limits in properties and observations to clarify that those references are made to ‘lower’ explosive limits
  • Many changes and additions to the dangerous goods list
  • Amendment and deletion of some special provisions
  • Several minor updates to the table of specimen labels in
  • Minor corrections to the text of and presentation of the SG codes in 7.2.8
  • SG29 and SG50 are now specifically referenced in the text in


It is extremely important that the most current regulations are applied when shipping dangerous goods in all modes for transportation, and this is why this corrigenda has been introduced. It is also worth noting that many of these changes apply to the printed IMDG Regulations and are either accurate in the digital copies or not applicable. 

But again, as we mentioned in the early onset, hazmat training online is essential to staying up to date and compliant with all of the latest dangerous goods shipping regulations and protocols.
