What is dangerous cargo and how to transport It safely? (using the example of batteries, flammable and toxic materials)

Modern logistics increasingly deals with goods that may pose potential risks during transportation — batteries, chemical reagents, pharmaceuticals, fuels, paints, solvents, and more. All of these belong to the category of Dangerous Goods. Such cargo requires special transport conditions, packaging, labeling, and accompanying documentation — particularly the MSDS (Material Safety Data Sheet).

What is dangerous cargo?

Dangerous cargo is any substance or product that, during transportation, can pose a risk to:

Human life and health,
The environment,
The integrity of the vehicle or other goods.

This definition is established by the ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road), as well as IMO (maritime) and IATA (air transport) regulations.

Main classes of dangerous goods

The international classification (UN / ADR) divides dangerous goods into nine classes, depending on the type of risk they pose during transportation:

Class 1 — Explosives.

This class includes items capable of exploding or causing an explosion when exposed to impact or heat. Examples: fireworks, ammunition.

Class 2 — Gases.

These may be compressed, liquefied, or dissolved gases. Examples: propane, butane, oxygen.

Class 3 — Flammable liquids.

Liquids that easily ignite when in contact with an open flame or heat. Examples: gasoline, solvents, alcohols.

Class 4 — Flammable solids.

Materials that can easily catch fire due to friction or heat. Examples: sulfur, sodium, magnesium.

Class 5 — Oxidizing substances.

Materials that release oxygen and can support the combustion of other substances. Examples: nitrates, peroxides.

Class 6 — Toxic and infectious materials.

Substances that are dangerous to human or animal health. Examples: poisons, chemicals, medical samples.

Class 7 — Radioactive materials.

Materials that emit ionizing radiation. Examples: isotopes, medical radiation sources.

Class 8 — Corrosive substances.

Substances that can damage metals, fabrics, skin, or other materials. Examples: acids, alkalis.

Class 9 — Miscellaneous dangerous substances.

This class includes materials that do not fit into previous categories but still pose a risk. Examples: lithium-ion batteries, electronics, environmentally hazardous substances.

Why batteries are considered dangerous cargo?

Batteries — especially lithium-ion ones — fall under Class 9 of dangerous goods. They can overheat, explode, or ignite when mechanically damaged or short-circuited.

Examples of goods considered dangerous due to batteries:

Smartphones, laptops, drones, e-scooters, power banks, electric vehicles;
Battery packs and charging stations;
Spare or replacement batteries.

What is an MSDS? (Material Safety Data Sheet)

An MSDS is a document containing detailed information about the composition, properties, risks, and handling instructions for a hazardous material. It is mandatory for every type of dangerous product — whether transported by sea, air, road, or rail.

Chemical composition;

Hazard level;

ADR class / UN code (e.g., UN3480 – lithium-ion batteries);

Storage and transport conditions;

Actions in case of fire or leakage;

Safety recommendations for personnel.

Without an MSDS, a logistics company or customs authority will not permit the transport of dangerous goods — it serves as the official confirmation of product safety compliance.

How dangerous goods are transported

1. Special packaging

Packaging must be sealed, impact- and moisture-resistant, and able to withstand drops.

For batteries — contact points must be insulated to prevent short circuits.

Each unit must display hazard labels, UN numbers, and warning symbols.

2. Documentation

In addition to the MSDS, the following documents are required:

Shipper’s declaration for dangerous goods;

Packing certificate;

Transport waybill indicating ADR class and UN number.

3. Transportation methods for dangerous goods

Dangerous goods can be transported in several ways, each with its own features, requirements, and advantages.

Road transport (ADR): The most common method in Europe. The driver must hold a special ADR certificate, and the vehicle must display a “Dangerous Goods” sign. This is a flexible and convenient option, but it is limited by distance and the quantity of cargo.

Rail transport: Used for transporting large quantities of hazardous materials. It requires special containers, wagons, and route approvals. This method is safer, but involves more formalities and longer preparation times for documentation.є спеціальної тари, вагонів та погодження маршруту. Такий спосіб є безпечнішим, проте вимагає більше формальностей і часу на підготовку документів.

Air transport: Regulated by IATA DGR (Dangerous Goods Regulations). Not all types of batteries and materials are allowed for air shipment. The main advantage is high delivery speed, but it is also the most expensive form of transportation.

Sea transport: Governed by the IMDG Code (International Maritime Dangerous Goods Code). This is the cheapest but also the slowest option. It is the best choice for transporting large volumes of goods over long distances.

How much does dangerous goods transport cost?

The cost depends on:

The hazard class (e.g., batteries = Class 9 — medium risk);

Transport mode;

Route distance;

Special packaging and certification needs.

Average surcharges:

Road (ADR): +15–30% to regular freight rates.

Air: +40–80%, sometimes double the cost.

Sea/Rail: +10–20% over base tariff.

Additional fees may apply:

For MSDS preparation ($30–$100);

ADR driver or freight surcharge;

UN-approved packaging.

Liability and fines

Violations of dangerous goods regulations may result in:

Fines up to ₴170,000 in Ukraine (for ADR violations);

Confiscation or delay of cargo at customs;

Denied insurance claims in case of incidents.

Dangerous cargo is not limited to chemicals or fuels — it also includes everyday electronics powered by batteries. To ensure legal and safe transportation, it is essential to: have a valid MSDS for each item; properly pack and label the cargo; use ADR / IATA / IMDG-certified transport; work with a logistics company experienced in handling dangerous goods. Only by following these steps can businesses avoid fines, delays, and risks to people and the environment.
