IMDG Code: What You Need to Know
IMDG Code Publication Schedule
Unlike the IATA DGR for air shippers, which is published annually, the IMDG Code is published once every 2 years. This unique publication schedule leads to "staggered" compliance requirements, which can cause confusion for vessel shippers.
The current edition of the IMDG Code is Amendment 37-14, also called the 2014 Edition. This edition was published in late 2014 for use in 2015 and throughout 2016. Any changes from the previous edition (2012) are indicated with symbols in the margins. Following is the explanation given in the current IMDG Code:
IMDG Code Voluntary Compliance Year
For the first year after a new edition of the IMDG Code is released, compliance with the new rules is voluntary. During a voluntary compliance year, hazmat shippers may use the current enforceable Code or the most recently published Code. In 2015, for example, shippers could have followed either the 2012 edition (still currently enforceable) or the new 2014 edition (published at the end of 2014).
IMDG Code Mandatory Compliance Year
The second year after a new edition is released, compliance with the new edition is mandatory. On January 1, 2016, for example, the 2012 edition of the IMDG Code becomes obsolete and you MUST comply with the 2014 edition. At the end of each mandatory compliance year, a new edition is published and the cycle begins again.
The one-year transition period between editions gives shippers time to prepare for changes that affect their operations, learn new regulations, and take the steps needed to comply. To ensure your shipping operations keep pace with updated packaging and shipping rules, a best management practice is to have a copy of the new edition of the IMDG Code well in advance of the mandatory compliance deadline. New and updated rules may require you to re-train personnel, change operating procedures, or possibly make adjustments to your hazmat shipping papers.
Significant Changes to the 2014 IMDG Code
Marine Pollutant Exclusions [IMDG 184.108.40.206]
In previous editions of the IMDG Code, marine pollutants packed in single or inner packagings with a capacity of not more than 5 L or 5 kg were excluded from marking requirements. Under the 2014 Code, marine pollutants packed in these amounts are not regulated as marine pollutants, which means they will not be described on shipping papers as marine pollutants either.
New and Revised Proper Shipping Names [IMDG 3.2]
The 2014 Edition of the IMDG Code made several additions and revisions to the Dangerous Goods List at IMDG 3.2, including:
- Amended Entries
- UN 3268: AIR BAG INFLATORS, AIR BAG MODULES, SEAT-BELT PRETENSIONERS are now called SAFETY DEVICES, electrically initiated
- UN 0503: AIR BAG INFLATORS, AIR BAG MODULES, SEAT-BELT PRETENSIONERS are now called SAFETY DEVICES, PYROTECHNIC
- UN 2212: BLUE ASBESTOS is now called ASBESTOS, AMPHIBOLE
- UN 2590: WHITE ASBESTOS is now called ASBESTOS, CHRYSOTILE
- New Entries
- UN3507, URANIUM HEXAFLUORUIDE RADIOACTIVE MATERIAL, EXCEPTED PACKAGE, 8, 7
- UN3508, CAPACITOR ASYMETRIC, 9
- UN3509, PACKAGING DISCARDED UNCLEANED, 9
- UN3510–3526 for various adsorbed gases in Class 2
The specifications (size, shape, color, etc.) for labels and placards in Chapter 5 of the IMDG Code have been rewritten to improve readability and reduce confusion. No substantive new requirements were created for the design of labels and placards. One new requirement filtering down from UN Model Regulations is that overpack markings must be at least 12mm high. [IMDG 220.127.116.11]
Portable Tanks With a Capacity of Not More Than 3,000 Liters
Various marking and placarding provisions for small portable tanks are relaxed in the new edition of the IMDG Code:
- Elevated-temperature and marine pollutant markings need only be 65 mm on each side, rather than 100 mm. [IMDG 18.104.22.168.1 and 22.214.171.124.2]
- Proper Shipping Name and ID number markings need only be 12 mm high, rather than 250 mm. [IMDG 126.96.36.199.2]
- Placards or labels are required only on two opposing sides instead of the usual four. [IMDG 188.8.131.52.4.1]
Column 16 of the Dangerous Goods List at Chapter 3.2, Stowage and Segregation, is now split into two columns. Column 16a is called Stowage and Handling, and Column 16b is called Segregation. Instead of appearing as text on the List, segregation and stowage instructions (e.g., "keep away from acids" or "stow apart from foodstuffs") now appear as alphanumeric codes. The meanings of the various codes are described in tables at the beginning of Chapter 7. [IMDG 7.1.5 and 7.2.8]
Revised Provisions for Class 7 Radioactives
In order to maintain harmonization with the International Atomic Energy Agency's regulations, packing instructions and other provisions for radioactive hazmat were extensively rewritten. [IMDG 1.5, 2.7, 4.1.9, 184.108.40.206.1, 220.127.116.11, 18.104.22.168.12, 22.214.171.124.7 and 6.4]

I think LION does an excellent job of any training they do. Materials provided are very useful to my day-to-day work activities.
Lion is at the top of the industry in compliance training. Course content and structure are updated frequently to make annual re-training enjoyable. I like that Lion has experts that I can contact for 1 year after the training.
The instructor's energy, enthusiasm, and knowledge of the subject make the class a great learning experience!
I was recently offered an opportunity to take my training through another company, but I politely declined. I only attend Lion Technology workshops.
Material Production/Logistics Manager
I attended training from another provider and learned absolutely nothing. Lion is much better. Hands down.
Lion was very responsive to my initial questions and the website was user friendly.
Supply Chain Director
The instructor had knowledge of regulations and understanding of real-world situations. The presentation style was engaging and fostered a positive atmosphere for information sharing.

Lion was very extensive. There was a lot of things that were covered that were actually pertaining to what I do and work with. Great Job. I will be coming back in three years!
