The Control of Explosives Precursors Regulations (Northern Ireland) 2014 came into force on 2 September 2014.

The Regulations were introduced to ensure that Northern Ireland complies with Regulation (EU) 98/2013 on the marketing and use of explosives precursors, while maintaining the existing explosives precursors controls that have been in place since the 1970s.

Some of the substances being controlled have legitimate uses and it is important that this legislation permits this while protecting against misuse.

In general terms, the legislation introduces a licensing scheme, requires additional labelling, and mandates reporting of suspicious activity with regards to certain named substances.

The Northern Ireland Office has provided detailed guidance on this legislation.
