About the IMDG Certification

One misdeclared drum or missing marine pollutant mark can hold a container at the terminal, trigger a carrier rejection and leave the shipper holding the liability. Companies moving hazardous cargo by sea need people who read the rulebook as the carrier and port do.

Fundamentals of IMDG builds that shared reading: how the code is organized, how a substance is classified and named, what packaging it may travel in, how it is marked, declared, packed into a unit and segregated aboard, and what to do when it leaks.

What You Will Learn

  • Locate any substance in the Dangerous Goods List by UN number or proper shipping name
  • Assign class, division, subsidiary risk and packing group using the classification decision path
  • Write a complete dangerous goods description, including marine pollutant status and N.O.S. entries
  • Read a packing instruction and match UN certified packaging to the packing group
  • Apply the right marks, labels and placards to packages and cargo transport units
  • Prepare a shipper's declaration and container packing certificate that survive an audit
  • Plan stowage and segregation aboard ship and pack a cargo transport unit to the CTU Code
  • Respond to a fire, spill or leak using EmS schedules and run a compliant end-to-end workflow

Who Is This Course For?

Any company whose cargo includes paints, batteries, aerosols, chemicals or other regulated substances has several teams touching the same shipment. Booking and documentation staff at freight forwarders and shipping lines prepare the declaration. Warehouse and port personnel pack, mark and stow the units. Logistics practitioners choose the packaging and the route, and compliance teams audit the result.

When each group has studied the same rulebook, handoffs stop producing surprises. A single-function cohort of declarants works well for a forwarder, while a mixed cohort of warehouse, booking and compliance staff suits a shipper or terminal operator that wants one standard across sites.

Course Outline

18 Modules30 hoursSelf-paced

The 18 modules move from the law to the paperwork and then onto the ship. Modules 1 to 3 set the regulatory scene and the structure of the code. Modules 4 to 6 cover classification, marine pollutants and the full cargo description. Modules 7 to 10 handle packaging, performance packaging, marking and the declaration.

Modules 11 to 13 go operational: stowage and segregation aboard ship, packing units under the CTU Code, and emergency response. Modules 14 to 17 cover roles and compliance culture, training and enforcement, lessons from container fires, and emerging trends. Module 18 is a capstone that runs a consignment through the whole workflow.

Frequently Asked Questions

Does it go beyond paperwork into stowage, segregation and emergencies?

Yes. Module 11 covers stowage categories, on-deck versus under-deck placement, the segregation table and reactive cargo combinations, and module 12 applies the CTU Code to inspecting, packing, securing and segregating a mixed-load unit. Module 13 deals with recognizing fire, spill, leakage and exposure, the EmS emergency schedules, escalation and reporting, and first response, and module 16 draws lessons from container-ship fires and mis-declaration cases.

How much attention goes to marine pollutants?

A full module. Module five defines marine pollutants and environmentally hazardous substances, explains the UN 3077 and UN 3082 entries, and shows how MARPOL Annex III interfaces with the code. Participants then learn to indicate pollutant status in the cargo description and apply the marine pollutant mark, so the environmental hazard is visible on the package, the unit and the declaration.

Will warehouse staff learn how to choose and check packaging?

Modules seven and eight are written for exactly that. Participants learn to read a packing instruction, understand inner, intermediate and outer layers, check chemical and physical compatibility, and handle overpacks. They then decode the UN packaging mark, see what design-type tests sit behind it and match certified packaging to the packing group of the substance they are shipping.

Is the documentation module relevant to a freight forwarder's booking desk?

Directly. Module ten walks through the shipper's dangerous goods declaration and the container or vehicle packing certificate, including the sequence and wording of the description and the need for data to agree across every document. Booking staff who accept declarations from customers learn what to check before a shipment is confirmed, and what to retain so the file is traceable later.

Does completing it satisfy our dangerous goods training obligations?

No claim of that kind is made. The program builds a working understanding of the code and its application, and an organization can use it to raise the baseline across booking, warehouse and compliance staff. Module 15 explains what the code itself requires in terms of mandatory training, competency and records, which helps you plan that separately. Whatever function-specific or regulator-mandated training applies to your operation remains your responsibility to arrange and record.

How do we track a cohort spread across several depots?

Through the administrator dashboard on the Blue Ocean learning platform. Once a corporate license is in place, every enrolled participant appears with enrollment status, progress through the 18 modules and completion, whichever depot or country they work from. Because the 30 hours are self-paced and available on web and mobile, shift workers can study in short sessions and your L&D lead still sees one consolidated picture.
