Summary of Significant Changes to the 2016 Edition of the IMDG Code

The international transportation of a dangerous good by vessel – over water – is subject to the dangerous goods code of the International Maritime Organization (IMO).

The IMDG Code is published by the IMO every two years.  In effect until the end of 2017 is the 2014 Edition which includes the 37-14 amendments.  It will be replaced on January 1, 2018 with the 2016 Edition which includes the 38-16 amendments (read: The IMDG Code Amendment Cycle – 2016 thru 2025).  The important thing to realize is this:  as of January 1, 2018, if you offer a dangerous good for international transportation by vessel you must comply with the 2016 Edition of the IMDG Code.  Therefore, as a shipper of dangerous goods you must be aware of any changes to the 2016 Edition from the 2014 Edition.  The purpose of this article is to summarize the significant changes to the 2016 Edition of the IMDG Code.

Remember, this only my summary of the significant changes to the 2016 Edition that have been identified by the IMO.  You can read the IMO’s more complete list here:  from the IMO website: Significant Changes to the 2016 Edition of the IMDG Code Also, you may refer to the reference marks which indicate changes to the IMDG Code from the previous edition.
