In international transport, dangerous goods (DG) are classified into nine classes under the International Maritime Dangerous Goods (IMDG) Code. Each class carries strict compliance requirements in booking, declaration, packaging and container loading. Here is a quick overview of the nine classes and typical products in each.
Fireworks, detonators, ammunition, etc. Most ocean carriers decline this class; it requires special approval and dedicated channels.
Compressed gases, aerosols (spray cans), lighters, fire extinguishers, etc. Subdivided into flammable, non-flammable non-toxic, and toxic gases.
Paint, coatings, alcohol, perfume, nail polish, adhesives, etc. One of the most common classes in daily exports.
Sulfur, matches, metallic sodium, certain activated carbon, etc.
Hydrogen peroxide, potassium permanganate, bleaching powder, etc. Risk of decomposition and explosion under heat or impact.
Pesticides, certain chemical raw materials, medical waste, etc.
Certain testing instruments and isotope products; requires specially licensed carriers.
Batteries containing acid, hydrochloric acid, caustic soda, cleaning agents, etc.
The broadest class — and the one most relevant to cross-border e-commerce and the energy storage industry. Lithium batteries and products containing lithium batteries (UN3480 lithium-ion batteries, UN3481 lithium batteries contained in equipment), e-bikes, hoverboards, portable power stations and automotive airbags all fall into this class.
DG exports involve many steps and strict compliance — a single mismatch can lead to booking rejection or even penalties.
