The Argentinian government adopted, on 22 August, 2022, new Mercosur rules concerning the inland transport of dangerous goods, covering both road and rail transport. 

Currently, the transport of dangerous goods in and between Mercosur countries (Argentina, Brazil, Paraguay and Uruguay) is regulated by a series of agreements established starting in 1994 (Mercosur Decisions 2/94, 14/94, 32/07 and 19/09). While maintaining the overall system, new rules introduced by Decision 15/19 will adapt it to align with changes in other global and international regulatory frameworks. 

Mercosur rules must be adopted individually by Member States, and become applicable once they have been ratified by all of them. While the initial deadline for adoption by Member States was July 1, 2020, only Uruguay and Argentina have completed their domestic transposition process.
