The above annexes and regulations, commonly known as ADR annexes and DNA regulations, regulate the international transport of dangerous goods by road and inland waterways between members of the UN Economic Commission for Europe (UNEA), who are also parties to ADR and DNA. The European agreement on the international transport of dangerous goods by inland waterways (DNA) was concluded on 26 May 2000 in Geneva at a diplomatic conference under the auspices of the United Nations Economic Commission for Europe (EEC-UN) and the Central Commission for the Navigation of the Rhine (CCNR). It came into force on February 29, 2008. 2. The EU is not a party to the European Agreement on the International Transport of Dangerous Goods by Road (`ADR`) and the European Agreement on the International Transport of Dangerous Goods by Inland Waterways (`DNA`). However, this circumstance does not prevent it from exercising its competence by defining, through its bodies, a position which must be defended on its behalf within the body established by this agreement, in particular by the Member States which are parties to this agreement and act together in their interest. The categories of dangerous goods according to the ADR are: The agreement itself is short and simple, and its most important article is Article 2. This article stipulates that hazardous substances, with the exception of certain exceptionally dangerous substances, can generally be transported internationally in wheeled vehicles, provided that two conditions are met: the draft proposal provides, in Article 1, a detailed list of proposed amendments which specify that they can be accepted by the Union. Given technological advances, the proposed changes are considered appropriate for the safe transportation of dangerous goods, given technological advances, and can therefore be supported. This structure is consistent with United Nations recommendations for the transport of dangerous goods, standard regulations, the International Code of Dangerous Shipping (the International Maritime Organization), technical instructions for the safe transport of dangerous goods by air (the International Civil Aviation Organization) and regulations relating to the international transport of dangerous goods by rail (the Intergovernmental Organization for International Rail Transport).
The development of the transport of dangerous goods by road and inland waterways, both within the Union and between the Union and neighbouring countries, is a key element of the common European transport policy and ensures the proper functioning of all industries that produce or use goods classified as aDR and DNA. Adapting to the technical and scientific progress of these agreements is therefore essential to enable the development of transport and related industries within the economic chain. The amendments are intended to adapt ADR and DNA to un standard rules, including new definitions, classification criteria and UN numbers, packaging and labelling requirements, updating applicable standards and technical provisions, and editorial corrections.
