What is ADR transport ?


What is ADR transport?

It turns out that not all products can be imported from China. This is due to the different criteria for the transport of dangerous goods. Due to differences between the laws in force in different parts of the world, some goods are not allowed for international transport.

What is ADR transport?

The commonly used ADR name is an abbreviation of the French name for the international convention L ‘Accord européen relatif au transport international des marchandises Dangereuses par Route.

The ADR agreement is based on the same fundamentals as other contracts for the transport of dangerous goods: by sea (IMDG), by air (ICAO) and by rail (RID).

We must remember that the rules for the transport of dangerous goods are not only determined by ADR convention but also by acts of the local law of individual countries.

According to international regulations, the transport of hazardous materials can take place by any technically prepared mode of transportation. Depending on the type of transported goods, there are guidelines on which mode of transport is the most appropriate. For example, products such as explosives,  flammable liquids, or radioactive materials are not allowed at all for sea transport. 

That is why in Europe is a legal division into a mode of transport by road ADR, rail RID, sea IMDG, air ICAO/IATA, and inland ADN. It is worth noting that changes to the regulations are updated every two years, except for air transport (IATA), which is updated every year.


ADR transport agreement

In addition to the applicable contract, specifying the main resolutions, the contract also contains annexes A and B.

Annex A contains a detailed classification of all materials considered dangerous in the world (classified by the UN in the TN catalog), i.e., being harmful to people, the environment, and material goods. It also determines the conditions of their transport. Each of these materials is given a four-digit number (the so-called “UN number”), and the agreement divides them into 13 hazard classes:

  • Class 1 Explosive substances and articles

  • Class 2 Gases, including compressed, liquified, and dissolved under pressure gases and vapors

  • Flammable gases (e.g., butane, propane, acetylene)

  • Non-flammable and non-toxic, likely to cause asphyxiation (e.g., nitrogen, CO2) or oxidizers (e.g., oxygen)

  • Toxic (e.g., Chlorine, Phosgene)vit

  • Class 3 Flammable liquids

  • Class 4.1 Flammable solids, self-reactive substances, and solid desensitized explosives

  • Class 4.2 Substances liable to spontaneous combustion

  • Class 4.3 Substances which, in contact with water, emit flammable gases

  • Class 5.1 Oxidizing substances

  • Class 5.2 Organic peroxides

  • Class 6.1 Toxic substances

  • Class 6.2 Infectious substances

  • Class 7 Radioactive material

  • Class 8 Corrosive substances

  • Class 9 Miscellaneous dangerous substances and articles

Annex B defines requirements for the vehicle crew and other persons involved in the transport, construction, and equipment of vehicles transporting hazardous materials (including trailers, cisterns, containers, etc.). It also contains information on the documentation required for transport and the rules for transporting this type of material through tunnels.

Other information about ADR transport

The vehicle transporting hazardous materials must be appropriately marked. Special warning stickers and boards in orange are used for this. In some cases, when the quantity of the product does not exceed the determined value, this rule does not apply.

The necessary equipment in which the driver must be equipped is the so-called “ADR box.” In any case, it must contain a wedge under the wheels and two standing warning signs, and in most cases, eyewash.

And ADR agreement also defines what the driver must fulfill requirements to transport hazardous materials. Drivers are required to have an ADR certificate, which can be purchased in progress of the appropriate course. Besides, the driver must be at least 21 years old.

As you can see, the requirements and regulations included in ADR are quite complicated and depend on many factors.


The ADR agreement is amended every two years in an odd year, so on January 1, 2019, its latest version entered into force. This version is obligatory from July 1, 2019.

Of all types of road transport, the transport of hazardous materials is undoubtedly one of the most complicated ones. Thanks to agreements such as ADR, we can be sure that these materials will be transported properly, without endangering the health and life of unauthorized persons and the environment.
