IMO / IMDG classes

Nine IMDG classes for dangerous goods - subclasses, examples, and reminders before you declare hazardous cargo.

Safety first

Classification, packaging, marking, and documentation must be validated by trained DG specialists - this guide is a reference, not legal advice.

Class 1

Explosives

Various goods based on their mass explosion hazard, projection hazard, or fire hazard.

Examples

Bombs, rockets, fuses, fireworks, ammunition, flares

Class 2

Gases

Gases can be compressed, or refrigerated from. Depending on their properties, these goods are separated into flammable, non-flammable, or toxic gases.

Examples

Propylene, ethane, butane, helium, chlorine

Class 3

Flammable Liquids

This classification includes flammable liquids and insensitive liquid explosives.

Examples

Turpentine, gasoline, paints, varnishes

Class 4

Flammable Solids

This class is divided into subcategories based on the properties of the solids.

Examples

Coal, ferrous metal shavings, wet cotton, sodium, potassium, calcium carbide

Class 5

Oxidizing Substances and Organic Peroxides

This class is divided into subcategories based on the properties of the substances.

Examples

Ammonium nitrate, hydrogen peroxide derivatives

Class 6

Toxic Substances

This class is divided into subcategories based on the properties of the substance.

Examples

Methanol, dichloromethane, diagnostic specimens, biological products

Class 7

Radioactive Material

Materials that contain radionuclides, such as uranium, plutonium, and thorium.

Examples

Uranium, plutonium, thorium

Class 8

Corrosive Substances

These substances have a corrosive effect when they come in contact with other substances, meaning that they can destroy living tissue.

Examples

Sulfuric acid, sodium hypochlorite

Class 9

Miscellaneous Dangerous Substances

This category includes substances not included in the other classes.

Examples

Dioxins, lithium batteries, dry ice

IMDG essentials

  • Classify, pack, mark, and declare DG before booking
  • Keep SDS and emergency contacts with the shipment file
  • Train warehouse and documentation staff on IMDG cycles
  • Use LogiFindex compliance tools for destination-specific checks

IMDG Code

Updated on a two-year cycle - always work from the amendment your carrier and port accept.

Training

Shore-side and ship personnel need role-based DG training aligned with IMDG Chapter 1.3.

Validate DG before dispatch

Use the AI Compliance Checker under Tools for destination rules, then confirm classification with your DG agent.

Never ship hazardous cargo on reference data alone.
