IMDG - International Maritime Dangerous Goods Shipping

Our IMDG training course has been designed with specific exercises related to the transportation of dangerous goods by water from a shipper's perspective. This course covers the fundamentals of shipping dangerous goods by vessel according to the IMDG regulations. Our 10-step approach encompasses all of the activities which must be addressed when preparing dangerous goods for shipment by water. This course is based on the 2018 Edition of the IMDG Code (Amendment 39-18).

The course is designed to help employers meet the requirements for training as specified in Section 1.3 of the IMDG Regulations and 49 CFR 172 Subpart H, including testing of participants. The focus of this course is on the preparation and shipment of non-bulk packages, intermediate bulk containers and large packagings.

The course does not address the packing of cargo transport units, as well as the stowage (placement), and segregation of dangerous goods on board a vessel. In addition, this course does not cover the more detailed requirements for the shipment of radioactive materials under IMDG.

In order to follow along with the examples and exercises presented in this course, you must have access to a copy of the IMDG.

The IMO announced a five-month delay in enforcement of the coming Amendment 40-20 of the IMDG Code due to the ongoing pandemic. The new mandatory date is June 1st, 2022 instead of January 1st, 2022. Voluntary compliance remains unchanged at January 1st, 2021.

Training Requirement

Citation: IMDG Chapter 1.3 and 49 CFR 172.704

Section 1.3 of the IMDG Code requires that:

Initial training occur for all “shore-based personnel engaged in the transport of dangerous goods intended to be transported by sea. The training shall be periodically supplemented with refresher training to take account of changes in regulations.”

US DOT's training requirements for shipping hazardous materials is located in 49 CFR Part 172 Subpart H. In addition to initial training [49 CFR 172.704(c)(1)], DOT requires "recurrent training" every 3 three years. 

"A hazmat employee shall receive the training required by this subpart at least once every three years." [49 CFR 172.704(c)(2)]

The IMDG Code does NOT reference a time frame for recurrent training. As such, the 3-year recurrent period stated in 49 CFR 172, Subpart H, applies.

Refresher Training Required: Every 3 year(s).

The course fee entitles a single user to participate in the online course for at least six (6) months. Requests for additional time will be considered on a case-by-case basis, but are almost always honored. Hardcopy certificates are mailed (first class for domestic locations/standard airmail for international locations) and included in the course fee. Expedited shipping costs are additional.
