The precursors of explosives are commonly-used chemicals (many of these are commonly used as fertilisers) that can be used for the illegal manufacture of explosives.
For this reason, on 2 September 2014, in the European Union, Regulation (EU) no. 98/2013 came into force on the marketing and use of explosives precursors, in which possible precursors were identified that are subject to restrictions on their sale to individuals. These substances are divided into two groups according to the hazard and the precautionary measures to be taken.
In fact, for some of these precursors, there is a ban on their sale to the public. With regard to these identified products, Regulation no. 98/2013 establishes the obligation for all operators involved to ensure appropriate labelling, to check licences, to keep a register and to report suspicious transactions to the national point of contact identified by each Member State.
