What is IMDG training?

Training for shipping dangerous goods by sea. Ocean transport is governed by the IMDG Code (International Maritime Dangerous Goods Code), issued by the International Maritime Organization. This training prepares you to classify, pack, mark, label, document, and container-pack dangerous goods for marine transport in line with the Code.

Anyone involved in preparing, handling, or offering dangerous goods for shipment by sea — shippers, packers, freight forwarders, and staff completing dangerous goods declarations and container packing certificates. Shore-side personnel who classify, document, or pack dangerous goods for ocean transport all fall within scope.

No. Ground TDG training doesn’t cover the marine requirements, which follow the IMDG Code and have their own classification details, packing provisions, segregation rules, and documentation. Shipping by sea without IMDG-specific training is a common compliance gap.

The IMDG Code has requirements specific to the marine environment — most notably marine pollutant identification, stowage and segregation rules for how goods are positioned relative to one another aboard a vessel, and container packing requirements. Documentation includes the Dangerous Goods Declaration and, where applicable, the Container/Vehicle Packing Certificate.

Certain substances are classified as harmful to the marine environment and carry additional identification, marking, and documentation requirements under the IMDG Code — even when they may not be as tightly regulated in other modes. Recognizing and correctly handling marine pollutants is a key part of the training.

Core areas include shipper responsibilities, classification, the IMDG Code structure and how to use it, packing and packaging provisions, marking and labelling, marine pollutants, segregation and stowage, container packing, and completing the Dangerous Goods Declaration. Depth is matched to your role.

Only for the modes you actually use — IATA/ICAO for air, 49 CFR or TDG for U.S./Canadian ground. Each mode has its own rules. If your shipments move across modes, we can build the combinations you need into one tailored program.

Yes. We provide both initial and refresher IMDG training and can help you track renewals so your team stays current with the latest amendments to the Code.
